Subject: [xsd-users] Codesynthesis and XPATH
Message-ID: <CAECSimP8-cf8GXpXe3bc0LfFzaz-dE4Cm=dxEm1TukZpnXS7fg@mail.gmail.com>

Hi

I want to use Codesynthesis to parse my xml against xsd and use the created
object and a given xpath(or any unique string to identify each node)  to
fetch the required child element.

Some ideas i am having
  Before generation of class from xsd, have some instruction to the XSD
binary  to  put some identifier for each element in the xsd and have this
mapping information available to be passed to an API , which will fetch the
required field value.

Does anyone have any pointers to achieve this?

I have tried using XQilla,  it does the job by using the DomDocument object
from already created Codesynthesis object, but it's really really slow,
has slowed down the performance of our product by 10 times. So we won't be
using it.

Thanks

Thank you boris

I checked the performance example and cached some high usage objects and
did improve the performance.

Hello,

I'm searching for the solution since ours and still didn't get it, so I decided to write a mail.
I have following complex Type in my xsd:

    <xsd:complexType name="VehicleMonitoringDelivery_t">
        <xsd:sequence>
            <xsd:element name="ResponseTimestamp" type="xsd:dateTime" minOccurs="0"/>
            <xsd:element name="SubscriberRef" type="xsd:string" minOccurs="0"/>
            <xsd:element name="SubscriptionRef" type="xsd:string" minOccurs="0"/>
            <xsd:element name="Status" type="xsd:boolean" minOccurs="0"/>
            <xsd:element name="VehicleActivity" type="VehicleActivity_t" minOccurs="0" maxOccurs="unbounded"/>
            <xsd:element name="Extensions" type="xsd:anyType" minOccurs="0"/>
        </xsd:sequence>
        <xsd:attribute name="version" type="xsd:NMTOKEN" default="2.0"/>
    </xsd:complexType>

There is an element "Extensions" with type "xsd:anyType".  I have generated a C++ code and want to create an xml. So I create an object of the type
"VehicleMonitoringDelivery_t" (example: myVehicleMonitoringDelivery) and fill it with numbers. For example:

myVehicleMonitoringDelivery-> SubscriberRef("1234");
myVehicleMonitoringDelivery-> Status(true);

and so on.

Now I wont to fill the "Extensions" with some, let say, string. WHO CAN I DO THAT? The na?ve approach

myVehicleMonitoringDelivery->Extensions("myString")

doesn't work, in the generated xml a get an empty tag <Extensions/>, although there is no errors.
It would be great if you can help me.

To quote the C++/Tree Mapping Manual:

"anyType allows any attributes and any content in any order. In the
C++/Tree mapping this content can be represented as a DOM fragment."

See Section 2.5.2, "Mapping for anyType" for details:

Hi,

I am trying to get started with XSD and QtCreator (Qt 5.7, mingw32).

I followed instructions at:
http://wiki.codesynthesis.com/Using_XSD_with_Qt_Creator
I have my INCLUDEPATH and LIBS configured.

I am trying to build the tree hello example, which has two 'source' files:
driver.cxx and hello.xsd

My .pro file looks like:

SOURCES += hello.xsd \

           driver.cxx


If I attempt to build, I get error:

"hello.hxx: no such file or directory"

hello.hxx is included from driver.cxx, but obviously has to be
generated from xsd


I figure there must be some configuration needed for QtCreator, to tell it that

xsd generation must be invoked (i.e., xsd rule included in makefile)

How do I do that?


Thanks

James

Subject: [xsd-users] xs:double with xs:restriction
Message-ID: <240bb5187a86434894de1fe5acb0c8b8@ll.mit.edu>

Hello,

I have a schema containing a simple data type that has the restriction <xs:pattern value="[0-9]\.[0-9]"/> with xs:double as the base type. The problem is that the output doesn't always match the pattern. For instance if the field's value is 8.0 then an output file has "<Field>8</Field>" rather than "<Field>8.0</Field>". Validating parsers flag this as an error since it doesn't match the pattern so is there a way to make this work or are pattern restrictions not supported for this case (i.e. non-string base types).

Thanks

You can't generally serialize a value in a way that matches a regex pattern.
What you can do is customize this type and provide custom serialization that
produces the desired format. See examples/cxx/tree/custom/double/ for how to
do this.

I am no QtCreator expert but I doubt this will be easy or even possible.
I would suggest that you start with just manually compiling your schema
and then adding the generated source files to the project. Once you have
this working, you can look if there is a way to automate it with a pre-
build step or some such.

Thanks, I went with a small app that iterated through dirs and ran xsd on
relevant files.
This could be made a pre-build step if needed.
Problem solved.
