Hi Lynn,
Use the following:
/foo/descendant::*[name() = 'a' or name() = 'b']/bar
Cheers,
Dimitre.

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
