RE: [xsl] RE: PLEASE HELP: SAX events and CDATA problem when using transformation chaining

["Andrew Welch" <AWelch@xxxxxxxxxxxxxxx>]

Yeah sorry about this one - it was a private email that I tried to take back on-list but sent to the xsl-list instead of the Xalan list!

Anyway, the crux of the matter was that the user had a cdata section on the source xml:

<RDF>
  <description><![CDATA[<<<<MY TEST>>>>]]></description>
</RDF>

And wanted to get identical output from an identity transform.  To achieve this, you need to set the cdata-section-elements attribute on <xsl:output> which they did, but still ended up with:  

<RDF>
  <description>&lt;&lt;&lt;&lt;MY TEST&gt;&gt;&gt;&gt;</description>
</RDF>

...as if the cdata-section-elements had been ignored.  I think they were using XML Spy, so I suggested that they may be using a custom processor instead of Xalan, but I have no experience of XML Spy so Im just guessing.  

cheers
