This may or may not be what you're looking for, but the DOM included with Internet Explorer 5, MSXML, allows you to enter an XPath expression as a parameter to the selectNodes() and selectSingleNode() methods. (Actually, it's not *real* XPath. It's based on a note submitted to the W3C for XQL, as memory serves. [It usually doesn't.] But it's pretty durned close, and when the next MSXML is released which is slated to have full 100% compliant XSL support, I'm assuming it will have full 100% compliant XPath support as well.) -----Original Message----- From: Leigh Dodds [mailto:ldodds@i...] Sent: Tuesday, December 14, 1999 8:32 AM To: xml-dev Subject: Xpath and DOM At present the DOM spec only allows one to traverse the tree 'manually' using getChild, etc. Or jump into the tree at some point using getElementsByTagName. Theres nothing in there to allow me to do getElementsByExpression (accepting an XPath search expression), or similarly pull out sections of the DOM tree using XPath expressions. I've written basic utilities to do this, as have others I'm sure (XSLT engines must use something similar), but I'm curious as to when, or even whether, this type of feature is going to be added to the DOM API itself. It would seem to be pretty useful. In the applications I've built so far, I've not wanted to traverse or walk the tree, just pick out bits of it (and sure I could use SAX but I want the tree in memory because I'm manipulating it multiple times). Unless I'm asking the wrong question - is there a tool that will search a DOM tree for me, assuming I supply it with an XPath expression.
