Hi all -
I have two questions regarding Ant, Xerces 2, and XInclude. I'm using Ant
1.6.5, and have upgraded its xercesImpl.jar and xml-apis.jar
to Xerces 2.8.0.
The first question is regarding XmlValidate. My understanding is that I
can turn on the XInclude feature with an <attribute> in the <xmlvalidate>
task:
<attribute name="http://apache.org/xml/features/xinclude"; value="true" />
When I try to validate, however, it fails on the <include> elements, as if
XInclude were not working.
My first guess was that I wasn't turning on the feature correctly, but I
noticed this in the Xerces 2 FAQ: "If the validation feature is turned on
then DTD validation will be performed on each source document (to the
XInclude processor) against their respective DTDs."
My Ant target for validation:
<target
name="validate-xerces"
>
<java classname="org.apache.xerces.impl.Version" />
<xmlvalidate
failonerror="yes"
warn="yes"
lenient="no">
<attribute name="http://apache.org/xml/features/xinclude";
value="true" />
<xmlcatalog>
<catalogpath>
<pathelement location="../schemas/docbook-4.4/catalog.xml"/>
</catalogpath>
</xmlcatalog>
<fileset
dir="${book.dir}"
includes="${book.file}" />
</xmlvalidate>
</target>
Is my task defined correctly to turn on XInclude? Is Xerces refusing to
do XInclude prior to DTD validation as a normal behavior? What is the
correct way for me to perform DTD validation with a document that uses
XInclude? (Must my DTD explicitly accommodate XInclude?)
My second question is regarding the Xslt task. I would like to turn on
the same Xerces feature for the purposes of XSLT processing (with Xalan).
I'm not clear on how to do this. I tried:
<target
name="xslt-xerces"
description="test XSLT with Xerces XInclude"
>
<java classname="org.apache.xerces.impl.Version" />
<xslt
in="${book.dir}/${book.file}"
out="${temp.dir}/test-xsl-out.txt"
style="test.xsl"
>
<factory>
<attribute name="http://apache.org/xml/features/xinclude";
value="true" />
</factory>
</xslt>
</target>
but got:
BUILD FAILED
/workplace/sandersd/Projects/NewAWSDocTools/AWSDocTools/tools/TEMP/build.xml:89:
java.lang.IllegalArgumentException: Not supported:
http://apache.org/xml/features/xinclude
What is the correct way to turn on XInclude with Xerces with the Xslt
task?
Thanks for any assistance you can provide! Let me know if I should post
more complete examples.
