[for the list's benefit, a tarball has been mailed.]

Well, at some future date I would like to be able to read in arbitrary,
possibly large-ish, XML documents, have them parsed into an accessible
structure and then be able to perform xpath/xquery queries on them to
isolate node(s).

Oh, ordered dictionaries as well? That would be great. 

I was wondering, earlier, what the most appropriate data-structure would be
for storing such a set of XML nodes, facilitating rapid random access. I'll
have a look through those sections imminently.
