The Expat-based implementation (in tcldom/src, formerly known
as TclDOM-Pro) doesn't include XPath support, and probably
never will unless someone else takes the trouble to implement it.
I don't plan to -- IMO implementing XPath is more trouble than
it's worth.

(Personally, I use a homegrown XML query language built on top
of TclDOM; it has most of the power of XPath, but was significantly
easier to implement).
