Must be a way: escaping filter patterns

[David Bovill]

Still trying to figure this out - my hack ends up failing - I've returned a
list of child names from XML, and wish to filter out all the "<tr>" elements
which appear like tr[1], tr[2]. So I want to filter using "tr[*]", but as
"[" is a special char... andthe usual "\[" does not work for escaping? Any
ideas?
