perhaps I missed something, but the one thing i strongly discouraged was
manually trying to parse markup language like html, xml, and the gang. i
haven't seen anyone else make any suggestions at all in this thread.
besides, if you read the original post:
http://lists.freebsd.org/pipermail/freebsd-questions/2004-April/044899.html
what he really wants is to search for some values that just happen to be
in an html document, manipulate them then replace with new values. these
values he's searching for have little to do with the surrounding markup
best I can tell.
none of this is to say i have offered the best possible solution. i don't
claim to be wise, expert, or 1337 when it comes to perl.
