HI All I have a question to ask. I have already posted that question but no response yet. Can I ask here?

@Imran You ask, but probably you're less likely to get an answer. Unless the answer is short & easy. (Fewer people visit. Things scroll off the page, and no one goes looking for people's unanswered questions as they do on the main site.)

Does anyone here use Mathematica to process XML? What I'm struggling with is the lack of a feature to match something only if it is contained within something else. This is making the code messy and difficult to work with.

I'm trying to do some transformations on some Adobe lens profiles to get a different sort of distortion correction.

@Szabolcs I've done a Cases with the right side of the :> being another Cases before.

@Szabolcs You could try jSoupLink. Example:

ParseHTML[
 "http://www.bovalpo.com/cgi-local/xml_bcv.pl?URL=4500",
 "fila columna:first-child",
 "text"
 ]

Sorry, forget about that. I didn't see the "transform" part. jSoup can do transformations, but I only implemented retrieval.
