Re: [xsl] Daisy chaining XSLT and also how can I check whether the XSLT processor supports a specific extension (specifically, ext:node-set)?

["ohaya ohaya@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

 Martin,
I don't remember mentioning Xalan, and actually THAT (which XSLT processor was
being used) was a question I had.


Given what I just found and posted about the testing on the product (that it
worked, but with the exslt: prefix and NOT with msxsl: prefix) - can we
conclude that the XSLT processor/engine on the product is Xalan?
Thanks,Jim

 I just tried (this was before your response below came in:

 B B B B B B B  </xsl:otherwise>
 B B B  </xsl:choose>
  And when I test under xsltproc on centos, I get:
   Test for exl:node-set() function
 +++++++++ exslt:node-set IS available


  a) Shouldn't my test (vs. your suggested code) be sufficient?B 


Yes, you can use that to test for support of EXSLT node-set.




  b) Also, per above I ran that on xsltproc on centos...
  If the above is good, then I need to try to run the same test on the
product, but, sorry, I forgot to mention that the product is running on
Windows, so should I change the namespace prefix in the code to "msxsl:"
instead of "exslt"?





In your previous messages I think you said it is Xalan C++, so no, don't use
the msxsl prefix, it works with Microsoft XSLT 1 processors like the various
versions of MSXML or .NET's obsolete XslTransform.
