I don't enjoy lengthy unfocused discussions/parallel monologues as much
as you (seem to) do, so I'm not going to try to address all of what you
write (sorry). This time I just somehow couldn't resist and replied to
the nonsense Drew wrote, which in hindsight was probably a mistake.

If you're interested in working with XML in Emacs Lisp, have a look at
the relevant Emacs Wiki page:

http://www.emacswiki.org/emacs/CategoryXML

Granted, the situation in Elisp is not nearly as good as in Scheme for
instance [1], but there is also an XPath implementation linked from
here:

http://www.emacswiki.org/emacs/XmlParser

[1] Which is quite understandable, given the relative quality of Elisp
the language (for me personally, having Scheme in Emacs/Emacs on Scheme
would be no less than a redemption), the related "policies", and how
some of (X)Emacs developers spend the limited amount of time available,
right?
