Re: include and redefine with XML Schema API

[Franz-Josef Herpers]

I've isolated and worked around my problem now. In fact it's the way I 
instantiate the
XMLInputSource from which my XMLSchemaLoader loads the grammar:

XMLInputSource is = new XMLInputSource(
				null,
				null,
				"file:/C://server_repository/xsd/",
				schemaFileInputStream,
				null);
As you can see I pass the constructor a baseSystemId and a 
FileInputStream. But the XMLSchemaLoader is apparently not able to 
resolve the relative schemaLocation-Attributes in my includes and 
redefines in the XML schema. But shouldn't that be enough information if 
 there is a baseURI against which the relative URIs aren being resolved?

The workaround I found is to pass the constructor a random systemId in 
the base directory:

XMLInputSource is = new XMLInputSource(
                                null,                   
"file:/C://server_repository/xsd/mySchema.xsd",
                                "file:/C://server_repository/xsd/",
                                schemaFileInputStream,
                                null);
That works, even if there is no file mySchema.xsd and I pass no 
baseSystemId into the constructor. The XMLLoader just takes the 
FileInputStream.

Can someone possibly spread some light on my confusion?
Thanks in advance
Franz

Hi *,
I'm using the XML Schema API to generate a tree based structure of the 
allowed elements and attributes of a XML Schema. Everything works fine 
and as expected with a few lines of code.

My problem is that I have to deal with XML Schmemas that use <include> 
and <redefine> elements. This seems not to be supported by the XML 
Schema API. The schema components which are defined in a include are 
simply not included and hence not retrieved by the interface methods of 
the API. I didn't find any methods to retrieve included or redefined 
schemas explicitly either.

So my question is: How can I handle XML Schemas wich use the include or 
redefine feature of XML Schema with the XML Schema API of Xerces-J. I'm 
using Xerces 2.6.0?

Thank you in advance for any suggestions and hints.
Regards
Franz
