Re: [xsl] Passing side documents to stylesheet (in Java)

[Andrew Franz <afranz0@xxxxxxxxxxxxxxxx>]

Hi Matynas,
I'm going through a PHP-to-Java conversion myself.

Using JSP and JSTL, I've used the following method:
(illustrating passing of request parameters)

In the JSP page:
   <x:parse var="requestXml">
   <params>
      <param id="action">${param['action']}</param>
      ...
   </params>
   </x:parse>
...
   <x:translate doc="<uri of XML document>" xslt="URI of XSLT document">
      <x:param name="rx" value="${requestXml"} />
      ...
   </x:translate>

In the XSLT:
   ...
   <xsl:param name="rx" />

   <p>Action:<xsl:value-of select="$rx/params/param[@id='action']" /><br/>
   ...

If it complains about result tree fragments, you can use Xalan-Java 
extensions, and the above becomes:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
   xmlns:java="http://xml.apache.org/xalan/java";
   exclude-result-prefixes="java">

   <xsl:param name="rx" />
...
   <p>Action:<xsl:value-of 
select="xalan:nodeset($rx)/params/param[@id='action']" /><br/>

More info about Xalan-Java extensions here:
   http://xml.apache.org/xalan-j/extensions.html#ext-functions


The other method is to use the document() function, but that's not 
really suitable for run-time documents.
The above passes a DOM document and it works because XSLT and JSTL have 
the same parser (Xalan) under Tomcat.
