Hi David, Thanks for the reply. Reg question #2, I refer to stylesheet by XSLT.
I have the stylesheet which returns boolean at the end of the transformation. I want to capture the boolean value from Xalan interface. Is this possible? The return type of XalanTransformer::transform() API is "integer" which tells whether the transformation is successful or not. But it is not helping the to get the actual value returned by Stylesheet. Hope i clarified myself this time.

Xalan-C parses an XML file into its internal source tree model, so the representation of the entire XML document will be in memory. Xalan-C can also wrap the Xerces-C DOM, but it's not very efficient, and never recommended unless you really need to do that. > > Also, currently XSLT returns the actual transformation result. Does > Xalan provides interface the return value of XSLT? I'm not sure what you mean by XSLT. If you mean can Xalan-C generate an instance of its source tree, so you can chain transformations, then the answer is yes. This is more efficient in terms of processing power, since the resulting serialized XML document doesn't have to be parsed to process it, but uses more memory, because you will end up with two source trees in memory at the same time.
