You have to change the syntax a bit to try this /foo[descendent::*[name()='a' or name()='b']]/bar But, this does not work to exclude the foo/a/b/a/x/a/bar type of elements. -Ramesh Pendakur -----Original Message----- From: Dimitre Novatchev [mailto:dnovatchev@xxxxxxxxx] Sent: Monday, December 04, 2000 11:45 AM To: lmonson@xxxxxxxxxxx; XSL-LIST Subject: Re: XPath optional node question Hi Lynn, Use the following: /foo/descendant::*[name() = 'a' or name() = 'b']/bar Cheers, Dimitre. Lynn Monson wrote: Hello all, I'm trying to write an XPath expression that matches optional elements in an element path. For example, suppose I have the following XPath expression: foo//bar But I want to allow any number (even zero) of "a" and "b" elements to exist where the "//" is. So my general expression would match the same nodes as, say, these xpaths: foo/a/bar foo/a/a/a/a/bar foo/a/b/bar foo/b/bar foo/bar But would not match nodes matched by: foo/x/bar I've been unable to construct a proper xpath. Any help would be greatly appreciated. Thanks __________________________________________________ Do You Yahoo!? Yahoo! Shopping - Thousands of Stores.
