RE: XPath for parent nodes, but excluding their childr
Thanks for clarifying Michael. That makes complete sense and was what I had assumed. I wanted to ensure I wasn't missing something obvious. -Joel -----Original Message----- From: Michael Kay [mailto:mike@xxxxxxxxxxxx] Sent: Thursday, June 30, 2011 5:25 PM To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: Re: XPath for parent nodes, but excluding their children There's a a lot of misunderstanding here. When you use an expression like //div, XPath selects the div elements only, it does not select their children or other descendants. It returns to the caller, in effect, pointers to these div elements. What happens next is up to the caller. It's quite common for the caller to process (e.g. display or copy) the whole subtree rooted at a selected element. Such behaviour can't be controlled using the XPath expression, because the XPath engine doesn't determine what the client does with the selected nodes. If you want to return to the client a node that doesn't have these children attached, you can't do this using XPath, because XPath can only select nodes as they exist in the input tree, it can't transform them into a different tree. That's XSLT territory.
