NAME

xsde - W3C XML Schema to C++ Compiler for Embedded Systems

SYNOPSIS

xsde command [options] file [file ...]

xsde help [command]

xsde version

DESCRIPTION

xsde generates vocabulary-specific, statically-typed C++ mapping from W3C XML Schema definitions. Particular mapping to produce is selected by a command. Each mapping has a number of mapping-specific options that should appear, if any, after the command. Input files should be W3C XML Schema definitions. The exact set of the generated files depends on the selected mapping and options.

COMMANDS

cxx-parser

Generate the Embedded C++/Parser mapping. For each input file in the form name.xsd the following C++ files are generated: name-pskel.hxx (parser skeleton header file), name-pskel.ixx (parser skeleton inline file, generated only if the --generate-inline option is specified), and name-pskel.cxx (parser skeleton source file). If the --generate-noop-impl or --generate-print-impl option is specified, the following additional sample implementation files are generated: name-pimpl.hxx (parser implementation header file) and name-pimpl.cxx (parser implementation source file). If the --generate-test-driver option is specified, the additional name-pdriver.cxx test driver file is generated.

cxx-serializer

Generate the Embedded C++/Serializer mapping. For each input file in the form name.xsd the following C++ files are generated: name-sskel.hxx (serializer skeleton header file), name-sskel.ixx (serializer skeleton inline file, generated only if the --generate-inline option is specified), and name-sskel.cxx (serializer skeleton source file). If the --generate-empty-impl option is specified, the following additional sample implementation files are generated: name-simpl.hxx (serializer implementation header file) and name-simpl.cxx (serializer implementation source file). If the --generate-test-driver option is specified, the additional name-sdriver.cxx test driver file is generated.

help

xsde help command

for command-specific help.

version

Print version and exit.

OPTIONS

Command-specific options, if any, should appear after the corresponding command.

common options

--output-dir dir

Write generated files to dir instead of the current directory.

--no-stl

Generate code that does not use the Standard Template Library (STL).

--no-iostream

Generate code that does not use the standard input/output stream library (iostream).

--no-exceptions

Generate code that does not use C++ exceptions.

--no-long-long

Generate code that does not use the long long and unsigned long long types. The 64 bit long and unsignedLong built-in XML Schema types are then mapped to long and unsigned long.

--generate-inline

Generate simple functions inline. This option triggers creation of the inline file.

--namespace-map xns=cns

Map XML Schema namespace xns to C++ namespace cns. Repeat this option to specify mapping for more than one XML Schema namespace. For example, the following option:

--namespace-map http://example.com/foo/bar=foo::bar

will map the http://example.com/foo/bar XML Schema namespace to the foo::bar C++ namespace.

--namespace-regex regex

Add regex to the list of regular expressions used to translate XML Schema namespace names to C++ namespace names. regex is a perl-like regular expression in the form /pattern/replacement/. Any character can be used as a delimiter instead of /. Escaping of the delimiter character in pattern or replacement is not supported.

All regular expressions are pushed into a stack with the last specified expression considered first. The first match that succeeds is used. Regular expressions are applied to a string in the form

filename namespace

For example,

XMLSchema.xsd http://www.w3.org/2001/XMLSchema

The filename for the current translation unit is empty. For example, if you have file hello.xsd with namespace http://example.com/hello and you run xsde on this file, then the string in question would be:

 http://example.com/hello

Note the leading space.

The following three steps are performed for each regular expression until the match is found:

1. The expression is applied and if the result is empty the next expression is considered.
2. All / are replaced with ::.
3. The result is verified to be a valid C++ scope name (e.g., foo::bar). If this test succeeds, the result is used as a C++ namespace name.

As an example, the following expression maps XML Schema namespaces in the form http://example.com/foo/bar to C++ namespaces in the form foo::bar:

%.* http://example.com/(.+)%$1%

See also the REGEX AND SHELL QUOTING section below.

--namespace-regex-trace

Trace the process of applying regular expressions specified with the --namespace-regex option. Use this option to find out why your regular expressions don't do what you expected them to do.

--reserved-name name[=rep]

Add name to the list of names that should not be used as identifiers. The name can optionally be followed by = and the replacement name that should be used instead. All C++ keywords are already in this list.

--include-with-brackets

Use angle brackets (<>) instead of quotes ("") in generated #include directives.

--include-prefix prefix

Add prefix to generated #include directive paths.

For example, if you had the following import element in your schema

<import namespace="..." schemaLocation="base.xsd"/>

and compiled this fragment with --include-prefix schemas/, then the include directive in the generated code would be:

#include "schemas/base.hxx"

--include-regex regex

Add regex to the list of regular expressions used to transform #include directive paths. regex is a perl-like regular expression in the form /pattern/replacement/. Any character can be used as a delimiter instead of /. Escaping of the delimiter character in pattern or replacement is not supported.

All regular expressions are pushed into a stack with the last specified expression considered first. The first match that succeeds is used.

As an example, the following expression transforms paths in the form schemas/foo/bar to paths in the form generated/foo/bar:

%schemas/(.+)%generated/$1%

See also the REGEX AND SHELL QUOTING section below.

--include-regex-trace

Trace the process of applying regular expressions specified with the --include-regex option. Use this option to find out why your regular expressions don't do what you expected them to do.

--guard-prefix prefix

Add prefix to generated header inclusion guards. The prefix is transformed to upper case and all characters that are illegal in a preprocessor macro name are replaced with underscores. If this option is not specified then the directory part of the input schema file is used as a prefix.

--hxx-suffix suffix

Use the provided suffix instead of the default .hxx to construct the name of the header file. Note that this suffix is also used to construct names for included/imported schemas.

--ixx-suffix suffix

Use the provided suffix instead of the default .ixx to construct the name of the inline file.

--cxx-suffix suffix

Use the provided suffix instead of the default .cxx to construct the name of the source file.

--hxx-regex regex

Use the provided expression to construct the name of the header file. regex is a perl-like regular expression in the form /pattern/replacement/. Note that this expression is also used to construct names for included/imported schemas. See also the REGEX AND SHELL QUOTING section below.

--ixx-regex regex

Use the provided expression to construct the name of the inline file. regex is a perl-like regular expression in the form /pattern/replacement/. See also the REGEX AND SHELL QUOTING section below.

--cxx-regex regex

Use the provided expression to construct the name of the source file. regex is a perl-like regular expression in the form /pattern/replacement/. See also the REGEX AND SHELL QUOTING section below.

--hxx-prologue text

Insert text at the beginning of the header file.

--ixx-prologue text

Insert text at the beginning of the inline file.

--cxx-prologue text

Insert text at the beginning of the source file.

--prologue text

Insert text at the beginning of each generated file for which there is no file-specific prologue.

--hxx-epilogue text

Insert text at the end of the header file.

--ixx-epilogue text

Insert text at the end of the inline file.

--cxx-epilogue text

Insert text at the end of the source file.

--epilogue text

Insert text at the end of each generated file for which there is no file-specific epilogue.

--hxx-prologue-file file

Insert the content of the file at the beginning of the header file.

--ixx-prologue-file file

Insert the content of the file at the beginning of the inline file.

--cxx-prologue-file file

Insert the content of the file at the beginning of the source file.

--prologue-file file

Insert the content of the file at the beginning of each generated file for which there is no file-specific prologue file.

--hxx-epilogue-file file

Insert the content of the file at the end of the header file.

--ixx-epilogue-file file

Insert the content of the file at the end of the inline file.

--cxx-epilogue-file file

Insert the content of the file at the end of the source file.

--epilogue-file file

Insert the content of the file at the end of each generated file for which there is no file-specific epilogue file.

--show-sloc

Show the number of generated physical source lines of code (SLOC).

--sloc-limit num

Check that the number of generated physical source lines of code (SLOC) does not exceed num.

--options-file file

Read additional options from file. Each option should appear on a separate line optionally followed by space and an argument. Empty lines and lines starting with # are ignored. The semantics of providing options in a file is equivalent to providing the same set of options in the same order in the command line at the point where the --options-file option is specified except that shell escaping and quoting is not required. Repeat this option to specify more than one options files.

--proprietary-license

Indicate that the generated code is licensed under a proprietary license instead of the GPL.

--preserve-anonymous

Preserve anonymous types. By default anonymous types are automatically named with names derived from the enclosing elements/attributes. Because mappings implemented by this compiler require all types to be named, this option is only useful if you want to make sure your schemas don't have anonymous types.

--show-anonymous

Show elements and attributes that are of anonymous types. This option only makes sense together with the --preserve-anonymous option.

--anonymous-regex regex

Add regex to the list of regular expressions used to derive names for anonymous types from the enclosing attributes/elements. regex is a perl-like regular expression in the form /pattern/replacement/. Any character can be used as a delimiter instead of /. Escaping of the delimiter character in pattern or replacement is not supported.

All regular expressions are pushed into a stack with the last specified expression considered first. The first match that succeeds is used. Regular expressions are applied to a string in the form

filename namespace xpath

For example,

hello.xsd http://example.com/hello element

hello.xsd http://example.com/hello type/element

The filename for the current translation unit is empty. For example, if you have file hello.xsd with namespace http://example.com/hello and you run xsde on this file, then the string in question would be:

 http://example.com/hello element

Note the leading space.

As an example, the following expression makes all the derived names start with capital letters. This could be useful when your naming convention requires type names to start with capital letters:

%.* .* (.+/)*(.+)%\u$2%

See also the REGEX AND SHELL QUOTING section below.

--anonymous-regex-trace

Trace the process of applying regular expressions specified with the --anonymous-regex option. Use this option to find out why your regular expressions don't do what you expected them to do.

--location-map ol=nl

Map original schema location ol that is specified in the XML Schema include or import elements to new schema location nl. Repeat this option to map more that one schema location. For example, the following option maps the http://example.com/foo.xsd URL to the foo.xsd local file.

--location-map http://example.com/foo.xsd=foo.xsd

--location-regex regex

Add regex to the list of regular expressions used to map schema locations that are specified in the XML Schema include or import elements. regex is a perl-like regular expression in the form /pattern/replacement/. Any character can be used as a delimiter instead of /. Escaping of the delimiter character in pattern or replacement is not supported. All regular expressions are pushed into a stack with the last specified expression considered first. The first match that succeeds is used.

For example, the following expression maps URL locations in the form http://example.com/foo/bar.xsd to local files in the form bar.xsd:

%http://.+/(.+)%$1%

See also the REGEX AND SHELL QUOTING section below.

--location-regex-trace

Trace the process of applying regular expressions specified with the --location-regex option. Use this option to find out why your regular expressions don't do what you expected them to do.

--file-per-type

Generate a separate set of C++ files for each type defined in XML Schema. Note that in this mode you only need to compile the root schema(s) and the code will be generated for all included and imported schemas. This compilation mode is primarily useful when some of your schemas cannot be compiled separately or have cyclic dependencies which involve type inheritance.

--type-file-regex regex

Add regex to the list of regular expressions used to translate type names to file names when the --type-per-file option is specified. regex is a perl-like regular expression in the form /pattern/replacement/. Any character can be used as a delimiter instead of /. Escaping of the delimiter character in pattern or replacement is not supported. All regular expressions are pushed into a stack with the last specified expression considered first. The first match that succeeds is used. Regular expressions are applied to a string in the form

namespace type-name

For example, the following expression maps type foo that is defined in the http://example.com/bar namespace to file name bar-foo:

%http://example.com/(.+) (.+)%$1-$2%

See also the REGEX AND SHELL QUOTING section below.

--type-file-regex-trace

Trace the process of applying regular expressions specified with the --type-file-regex option. Use this option to find out why your regular expressions don't do what you expected them to do.

--file-list file

Write a list of generated C++ files to file. This option is primarily useful in the file-per-type compilation mode (--file-per-type) to create a list of generated C++ files, for example, as a makefile fragment.

--file-list-prologue text

Insert text at the beginning of the file list. As a convenience, all occurrences of the \n character sequence in text are replaced with new lines. This option can, for example, be used to assign the generated file list to a makefile variable.

--file-list-epilogue text

Insert text at the end of the file list. As a convenience, all occurrences of the \n character sequence in text are replaced with new lines.

--file-list-delim text

Delimit file names written to the file list with text instead of new lines. As a convenience, all occurrences of the \n character sequence in text are replaced with new lines.

cxx-parser command options

--type-map mapfile

Read XML Schema to C++ type mapping information from mapfile. Repeat this option to specify several type maps. Type maps are considered in order of appearance and the first match is used. By default all user-defined types are mapped to void. See the TYPE MAP section below for more information.

--reuse-style-mixin

Generate code that supports the mixin base parser implementation reuse style. Note that this reuse style relies on virtual inheritance and may result in a substantial object code size increase for large vocabularies. By default support for the tiein style is generated.

--reuse-style-none

Do not generate any support for base parser implementation reuse. By default support for the tiein style is generated.

--suppress-validation

Suppress generation of validation code.

--generate-polymorphic

Generate polymorphism-aware code. Specify this option if you use substitution groups or xsi:type.

--runtime-polymorphic

Generate non-polymorphic code that uses the runtime library configured with polymorphism support.

--suppress-reset

Suppress generation of parser reset code. Reset support allows you to reuse parsers after an error.

--generate-noop-impl

Generate a sample parser implementation that does nothing (no operation). The sample implementation can then be filled with the application-specific code. For an input file in the form name.xsd this option triggers generation of the two additional C++ files in the form: name-pimpl.hxx (parser implementation header file) and name-pimpl.cxx (parser implementation source file).

--generate-print-impl

Generate a sample parser implementation that prints the XML data to STDOUT. For an input file in the form name.xsd this option triggers generation of the two additional C++ files in the form: name-pimpl.hxx (parser implementation header file) and name-pimpl.cxx (parser implementation source file).

--generate-test-driver

Generate a test driver for the sample parser implementation. For an input file in the form name.xsd this option triggers generation of an additional C++ file in the form name-pdriver.cxx.

--force-overwrite

Force overwriting of the existing implementation and test driver files. Use this option only if you do not mind loosing the changes you have made in the sample implementation or test driver files.

--root-element-first

Indicate that the first global element is the document root. This information is used to generate the test driver for the sample implementation.

--root-element-last

Indicate that the last global element is the document root. This information is used to generate the test driver for the sample implementation.

--root-element element

Indicate that element is the document root. This information is used to generate the test driver for the sample implementation.

--generate-xml-schema

Generate a C++ header file as if the schema being compiled defines the XML Schema namespace. In particular, the resulting file will have definitions for all parser skeletons and implementations corresponding to the XML Schema built-in types. The schema file provided to the compiler need not exist and is only used to derive the name of the resulting header file. Use the --extern-xml-schema option to include this file in the generated files for other schemas.

--extern-xml-schema file

Include a header file derived from file instead of generating the XML Schema namespace mapping inline. The provided file need not exist and is only used to derive the name of the included header file. Use the --generate-xml-schema option to generate this header file.

--skel-type-suffix suffix

Use the provided suffix instead of the default _pskel to construct the names of generated parser skeletons.

--skel-file-suffix suffix

Use the provided suffix instead of the default -pskel to construct the names of generated parser skeleton files.

--suppress-reset

Suppress generation of serializer reset code. Reset support allows you to reuse serializers after an error.

--generate-empty-impl

Generate a sample serializer implementation with empty function bodies which can then be filled with the application-specific code. For an input file in the form name.xsd this option triggers generation of the two additional C++ files in the form: name-simpl.hxx (serializer implementation header file) and name-simpl.cxx (serializer implementation source file).

--generate-test-driver

Generate a test driver for the sample serializer implementation. For an input file in the form name.xsd this option triggers generation of an additional C++ file in the form name-sdriver.cxx.

In particular, the resulting file will have definitions for all serializer skeletons and implementations corresponding to the XML Schema built-in types. The schema file provided to the compiler need not exist and is only used to derive the name of the resulting header file. Use the --extern-xml-schema option to include this file in the generated files for other schemas.

--extern-xml-schema file

Include a header file derived from file instead of generating the XML Schema namespace mapping inline. The provided file need not exist and is only used to derive the name of the included header file. Use the --generate-xml-schema option to generate this header file.

Use the provided suffix instead of the default _simpl to construct the names of serializer implementations for the built-in XML Schema types and sample serializer implementations.

--impl-file-suffix suffix

Use the provided suffix instead of the default -simpl to construct the names of generated sample serializer implementation files.

TYPE MAP

Type map files are used to define a mapping between XML Schema and C++ types. For C++/Parser, the compiler uses this information to determine the return types of post_* functions in parser skeletons corresponding to XML Schema types as well as argument types for callbacks corresponding to elements and attributes of these types. For C++/Serializer, type maps are used to determine the argument type of pre functions in serializer skeletons corresponding to XML Schema types as well as return types for callbacks corresponding to elements and attributes of these types.

The compiler has a set of predefined mapping rules that map the built-in XML Schema types to suitable C++ types (discussed in the following sub-sections) and all other types to void. By providing your own type maps you can override these predefined rules. The format of the type map file is presented below:

namespace <schema-namespace> [<cxx-namespace>]
{
  (include <file-name>;)*
  ([type] <schema-type> <cxx-ret-type> [<cxx-arg-type>];)*
}
  

Both <schema-namespace> and <schema-type> are regex patterns while <cxx-namespace>, <cxx-ret-type>, and <cxx-arg-type> are regex pattern substitutions. All names can be optionally enclosed in " ", for example, to include white-spaces.

<schema-namespace> determines XML Schema namespace. Optional <cxx-namespace> is prefixed to every C++ type name in this namespace declaration. <cxx-ret-type> is a C++ type name that is used as a return type for the post_* function in C++/Parser or for element/attribute callbacks in C++/Serializer. Optional <cxx-arg-type> is an argument type for element/attribute callbacks in C++/Parser or for the pre function in C++/Serializer. If <cxx-arg-type> is not specified, it defaults to <cxx-ret-type> if <cxx-ret-type> ends with * or & (that is, it is a pointer or a reference) and const <cxx-ret-type>& otherwise. <file-name> is a file name either in the " " or < > format and is added with the #include directive to the generated code.

The # character starts a comment that ends with a new line or end of file. To specify a name that contains # enclose it in " ". For example:

namespace http://www.example.com/xmlns/my my
{
  include "my.hxx";

  # Pass apples by value.
  #
  apple apple;

  # Pass oranges as pointers.
  #
  orange orange_t*;
}
  

In the example above, for the http://www.example.com/xmlns/my#orange XML Schema type, the my::orange_t* C++ type will be used as both return and argument types.

Several namespace declarations can be specified in a single file. The namespace declaration can also be completely omitted to map types in a schema without a namespace. For instance:

include "my.hxx";
apple apple;

namespace http://www.example.com/xmlns/my
{
  orange "const orange_t*";
}
  

The compiler has a number of predefined mapping rules for the built-in XML Schema types that vary depending on the mapping used. They are described in the following subsections. The last predefined rule for all mappings maps anything that wasn't mapped by previous rules to void:

namespace .*
{
  .* void void;
}
  

When you provide your own type maps with the --type-map option, they are evaluated first. This allows you to selectively override predefined rules.

Predefined C++/Parser Type Maps

The C++/Parser mapping provides a number of predefined type map rules for the built-in XML Schema types. They can be presented as the following map files:

namespace http://www.w3.org/2001/XMLSchema
{
  boolean bool bool;

  byte "signed char" "signed char";
  unsignedByte "unsigned char" "unsigned char";

  short short short;
  unsignedShort "unsigned short" "unsigned short";

  int int int;
  unsignedInt "unsigned int" "unsigned int";

  long "long long" "long long";
  unsignedLong "unsigned long long" "unsigned long long";

  integer long long;

  negativeInteger long long;
  nonPositiveInteger long long;

  positiveInteger "unsigned long" "unsigned long";
  nonNegativeInteger "unsigned long" "unsigned long";

  float float float;
  double double double;
  decimal double double;

  base64Binary xml_schema::buffer*;
  hexBinary xml_schema::buffer*;

  date xml_schema::date;
  dateTime xml_schema::date_time;
  duration xml_schema::duration;
  gDay xml_schema::gday;
  gMonth xml_schema::gmonth;
  gMonthDay xml_schema::gmonth_day;
  gYear xml_schema::gyear;
  gYearMonth xml_schema::gyear_month;
  time xml_schema::time;
}
  

If the --no-stl option is not specified, the following mapping is used for the string-based XML Schema built-in types:

namespace http://www.w3.org/2001/XMLSchema
{
  include <string>;

  string std::string;
  normalizedString std::string;
  token std::string;
  Name std::string;
  NMTOKEN std::string;
  NCName std::string;
  ID std::string;
  IDREF std::string;
  language std::string;
  anyURI std::string;

  QName xml_schema::qname;

  NMTOKENS xml_schema::string_sequence;
  IDREFS xml_schema::string_sequence;
}
  

Otherwise, a C string-based mapping is used:

namespace http://www.w3.org/2001/XMLSchema
{
  string char*;
  normalizedString char*;
  token char*;
  Name char*;
  NMTOKEN char*;
  NCName char*;
  ID char*;
  IDREF char*;
  language char*;
  anyURI char*;

  QName xml_schema::qname*;

  NMTOKENS xml_schema::string_sequence*;
  IDREFS xml_schema::string_sequence*;
}
  

Predefined C++/Serializer Type Maps

The C++/Serializer mapping provides a number of predefined type map rules for the built-in XML Schema types. They can be presented as the following map files:

namespace http://www.w3.org/2001/XMLSchema
{
  boolean bool bool;

  byte "signed char" "signed char";
  unsignedByte "unsigned char" "unsigned char";

  short short short;
  unsignedShort "unsigned short" "unsigned short";

  int int int;
  unsignedInt "unsigned int" "unsigned int";

  long "long long" "long long";
  unsignedLong "unsigned long long" "unsigned long long";

  integer long long;

  negativeInteger long long;
  nonPositiveInteger long long;

  positiveInteger "unsigned long" "unsigned long";
  nonNegativeInteger "unsigned long" "unsigned long";

  float float float;
  double double double;
  decimal double double;

  base64Binary "const xml_schema::buffer*";
  hexBinary "const xml_schema::buffer*";

  date xml_schema::date;
  dateTime xml_schema::date_time;
  duration xml_schema::duration;
  gDay xml_schema::gday;
  gMonth xml_schema::gmonth;
  gMonthDay xml_schema::gmonth_day;
  gYear xml_schema::gyear;
  gYearMonth xml_schema::gyear_month;
  time xml_schema::time;
}
  

If the --no-stl option is not specified, the following mapping is used for the string-based XML Schema built-in types:

namespace http://www.w3.org/2001/XMLSchema
{
  include <string>;

  string std::string;
  normalizedString std::string;
  token std::string;
  Name std::string;
  NMTOKEN std::string;
  NCName std::string;
  ID std::string;
  IDREF std::string;
  language std::string;
  anyURI std::string;

  QName xml_schema::qname;

  NMTOKENS xml_schema::string_sequence;
  IDREFS xml_schema::string_sequence;
}
  

Otherwise, a C string-based mapping is used:

namespace http://www.w3.org/2001/XMLSchema
{
  string "const char*";
  normalizedString "const char*";
  token "const char*";
  Name "const char*";
  NMTOKEN "const char*";
  NCName "const char*";
  ID "const char*";
  IDREF "const char*";
  language "const char*";
  anyURI "const char*";

  QName "const xml_schema::qname*";

  NMTOKENS "const xml_schema::string_sequence*";
  IDREFS "const xml_schema::string_sequence*";
}
  

REGEX AND SHELL QUOTING

When entering a regular expression argument in the shell command line it is often necessary to use quoting (enclosing the argument in " " or ' ') in order to prevent the shell from interpreting certain characters, for example, spaces as argument separators and $ as variable expansions.

Unfortunately it is hard to achieve this in a manner that is portable across POSIX shells, such as those found on GNU/Linux and UNIX, and Windows shell. For example, if you use " " for quoting you will get a wrong result with POSIX shells if your expression contains $. The standard way of dealing with this on POSIX systems is to use ' ' instead. Unfortunately, Windows shell does not remove ' ' from arguments when they are passed to applications. As a result you may have to use ' ' for POSIX and " " for Windows ($ is not treated as a special character on Windows).

Alternatively, you can save regular expression options into a file, one option per line, and use this file with the --options-file option. With this approach you don't need to worry about shell quoting.

DIAGNOSTICS

If the input file is not a valid W3C XML Schema definition, xsde will issue diagnostic messages to STDERR and exit with non-zero exit code.
