Title: How to use Xpath from Xalan.

The document itself is a node. In your case the document is the context. Just pass the address to the document as context.   / Erik   -----Original Message----- From: Sami Islam [mailto:[EMAIL PROTECTED] Sent: den 19 maj 2004 10:16 To: Xalan User List Subject: How to use Xpath from Xalan.   Hello, I need some clarification on how to correctly use the XPathEvaluator in Xalan. In the sample programs from Xalan 1.7 the evaluator is first used : 1) to find the context node. 2) to find the list of nodes. 3) finally evaluate the result. My questions: 1) Do I have to get a context node? e.g. If I want the node at /doc/[EMAIL PROTECTED]'Tom']/@last do I have to first get the context node for "/" and then evaluate the _expression_ "doc/[EMAIL PROTECTED]'Tom']/@last? Isn't there a way I can just obtain the node directly without the 1) step. e.g. evaluator.selectSingleNode(..., ...,  XalanDOMString("/doc/[EMAIL PROTECTED]'tom')/@last").c_str( ), ...); instead of evaluator.selectSingleNode(..., ...,  XalanDOMString("/").c_str( ), ...); first. The only thing that is unclear to me is the evaluator.evaluate( ) member function that takes a "context_node" as its second parameter and "XpathString" as its third.  Regards, Sami
