Gentlemen,
I have a web application that uses, on the browser-side, XSL transforms.
Alas, because of a little issue in WebKit (affecting Google Chrome,
Safari, ...), I cannot use composed XSLTs (i.e., XSLs that
<xsl:include>s other bits of XSL) in Chrome.
I thought I'd give xalan-java a try at solving my problem, by
"composing" the XSLT bits into one big XSL, on the server-side.
That composed XSL could then be used by all browsers.
Here's what I had in mind:
* get xalan-java to load the XSL.
* get xalan-java to load its children.
* dump the composed XSL as String, or byte [].
And here's my first attempt at this task:
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer
(new StreamSource("/path/to/xslt/common.xslt"));
TransformerImpl transformerImpl = (TransformerImpl) transformer;
StylesheetRoot stylesheetRoot = transformerImpl.getStylesheet();
stylesheetRoot.recompose();
Document stylesheetDoc = stylesheetRoot.getOwnerDocument();
W3CNodeHelper nodeHelper = new W3CNodeHelper();
String out =
nodeHelper.dumpAsString(stylesheetDoc.getChildNodes().item(0));
(Where the "W3CNodeHelper" thingy is just one of our tools I use to dump
the document.)
Unfortunately this fails, as:
java.lang.RuntimeException: ElemTemplateElement error: Function not
supported!

I guess this method is far from ideal. Would anyone have any information
on how I could achieve what I'm trying to?
Thanks a bunch for any info/pointer!

A.
