Hi !

I`m using xmllib 2.6.13 to parse xsd files. How to get the namespace of type t:mybase of this sample schema:

<?xml version="1.0" encoding="UTF-8"?>

<xs:schema targetNamespace="urn:bsp" xmlns:t="urn:bsp"

elementFormDefault="qualified" attributeFormDefault="unqualified"

xmlns:xs=""; >

        <xs:element name="baselem" type="t:mybase"/>

        <xs:complexType name="mybase">

                <xs:sequence id="baseseq">

                        <xs:element name="base1" type="xs:string"/>

                        <xs:element name="base2" type="xs:string"/>




I tried to get it from a pointer xmlSchemaTypePtr ptype – but couldn`t find it.

There is no targetNamespace field in the xmlSchemaType yet.

ptype->name=“mybase“, but there is no namespace field – the namespace should be urn:bsp.

Can anyone help me ?

Since AFAIK the targetNamespace of complex/simple types is not involved
in any schema construction or validation process, it was not exposed

Sorry, this might be misleading: "schema construction" was meant here in
the sence of applying constraints to the schema itself, i.e. derivation
constraints, etc. The only intent for the targetNamespace in a simple/
complex type is to distinguish them from other complex/simple type
components with the same name.

yet. It would only be usefull for display purposes, and for construction
of schemata using an API, which is not supported yet; construction from
XML Schema _documents_ is implemented only. A quick workaround would be
to take the targetNamespace of the schema itself, since it's always the
same. For a schema build from different schema documents by import this
workaround would obviously not work.
The spec declares the targetNamespace as part of the complex/simple type
component, so we will have to put it in anyway. I'll look into it.

It would be interesting if you could describe your use case here.
