Creating Xalan document from data stream

[Coker, Jonathan M]

Hello,
   I would like to be able to us Xalan/XPath  to extract data from a
chunk of XML that I will be receiving over a network.  My current plan
involves using Xerces, MemBufInputSource, and the
XercesDOMWrapperParsedSource to get a Xalan document.  Is there an
easier more direct way to do this?  I am trying to avoid SAX2 because I
would like to us XPath, and I saw no interoperability with that.  Thanks
for any help.
