XPathAPI setting variables

[Philip Dodds <Ph...@unity-systems.com>]

   I have been trying to set variables for use on an XPathAPI.execute(...), 
   I realize that I can get the XPathContext and from there get the
   VariableStack,  however I'm not exactly sure how to use this?

   

   I was hoping to be able to place a variable on the stack though looking
   through the code this seems to be handled though use of the StylesheetRoot
   returning a vector then updating the VariableStack?  I'm a little lost on
   why methods don't exist in the VariableStack for adding a variable.

   

   Is there a way to set up the VariableStack to add a variable
   programmatically based on the result of an XPath?  In other words creating
   an XObject and then giving it a QName and placing it on the stack so I can
   re-use this on the XPathAPI?

   

   Cheers

   Philip

     The XPath API of JAXP 1.3 includes an XPathVariableResolver interface 
that allows one to supply the value of a variable for XPath expression 
evaluation.  Once there is a release of Xalan-Java that includes support 
for JAXP 1.3, that should solve your problem.  Do you need a solution in 
the interim?

Thanks,
