differences between URIResolver in Xalan and XSLTC 2003-01-02 - By zongaro@(protected)
Hi Christos,
It depends on the arguments to the document() function.
According to section 12.1 of XSLT 1.0 [1], if the document() function
has two arguments (in which case the second argument must be a node-set)
the base URI for the reference is the base URI of the first node in the
second argument in document order; if the document() function has one
argument, and that argument is a node set, the result is the union of a
number of references to document() with two arguments, as described in
12.1. In both of those cases, the base URI would likely be the base URI
of a node in the XML document.
If the reference to the document() function has no arguments or has
one argument, and that argument is not a node-set, the base URI for the
reference is, according to 12.1, the base URI of the node in the
stylesheet that contains the reference to document().
You might be encountering the same problem as Bug 15200.[2] If it
appears to be a distinct problem, please open a bug report in Bugzilla.
Thanks,
Henry

Subject: differences between URIResolver in Xalan and XSLTC
I am modifying an application to use XSLTC instead of Xalan. The
application uses a custom URIResolver to resolve document() refrences in
stylesheets, and when the resolver is called, it gets different values
for the "base" parameter depending on if I'm using Xalan or XSLTC:
- With Xalan, the base is the system id that was assigned to the
*stylesheet's* Source
- However, with XSLTC, the base is the system id that was assigned to
the *xml document's* Source
Which one, of Xalan or XSLTC, is calling my URIResolver the right way?
For exemple:
StreamSource srcXSL = new StreamSource(inXSL);
srcXSL.setSystemId("stylesheet.xsl");
Templates template = transformerFactory.newTemplates(srcXSL);
Transformer transformer = template.newTransformer();
transformer.setURIResolver(new TestURIResolver());
StreamSource srcXML = new StreamSource(inXML);
srcXML.setSystemId("document.xml");
transformer.transform(srcXML, out);
When I use XSLTC, TestURIResolver.resolve() is called with
"document.xml" as a base, and when I switch back to Xalan, it is called
with "stylesheet.xsl" as a base.
I'm using Xalan 2.4.1
Thanks
