Parsing HTML is a context-free parsing problem (since the tags can embed and you have to have a stack to track the things you want to match), not a regular expression parsing problem (there's no fixed bound of memory you need to do this job). So what you might want to do is to try to grab up a true HTML parser (I think there are perl modules for this), and then walk the resulting tree.... --------------------------------------------------------------------- To unsubscribe, e-mail: tclug-list-unsubscribe at mn-linux.org For additional commands, e-mail: tclug-list-help at mn-linux.org
