[xsd-users] Help for User Defined Types

[Jones, Monte J CTR USAF AFSPC SLG/WML]

I am attempting to parse an XML with user defined data types.  I am
using these because some of these data types appear in multiple places
in the XML document.  For example one of the types I have is a location
which is defined as indicated below.  I use this for many assets, each
with different other parameters.

 

<xsd:complextType name="Location">

    <xsd:sequence>

        <xsd:element name="Latitude">

            <xsd:restriction base="xsd:float">

                <xsd:minInclusive value="-90.0" />

                <xsd:maxInclusive value="90.0" />

            </xsd:restriction>

        </xsd:element>

        <xsd:element name="Longitude">

            <xsd:restriction base="xsd:float">

                <xsd:minInclusive value="-180.0" />

                <xsd:maxInclusive value="180.0" />

            </xsd:restriction>

        </xsd:element>

        <xsd:element name="Altitude">

            <xsd:restriction base="xsd:float">

                <xsd:minInclusive value="-300.0" />

                <xsd:maxInclusive value="43000.0" />

            </xsd:restriction>

        </xsd:element>

    </xsd:sequence>

</xsd:complexType>

 

Here is the example of how I am using my type in the xsd.

    <xsd:element name="Site_Location" type ="lib:Location" />

 

 

The schema validates, and the parser code compiles but does not link.  I
think the problem comes in the Location contains no actual data, only
the definitions of data.  The auto generated -pskel and -pimpl files
have shells for parsing Location data, but then I am having trouble with
the use for different assets because I do not have a defined
implementation for the shell.

 

We have used Xerces-C and Code Synthesis XSD a lot, but none of the
previous implementations contained user defined types.  I really think
this is a misunderstanding on my part about what to do, not a product
problem.  Can anyone point me in the right direction for including,
using, and parsing user defined types?
