freshwebs Posted December 23, 2006 Share Posted December 23, 2006 How do I match all characters except for a certain word? I need to match text which may contain line breaks but stop when it comes to a </div> tag. I've just been using "<div>([[:print:][:space:]]*?)</div>" but I feel like there's a better way to do it.Thanks for any help!Aaron Quote Link to comment Share on other sites More sharing options...
c4onastick Posted December 24, 2006 Share Posted December 24, 2006 That's it right there, this is a great use of lazy quantifiers (the *? in this example). You could get fancy (read: crazy) and do something like:[code]preg_match_all('/<div>([^<]*(?:<(?!\/div)|[^<]*)*)<\/div>/is', $html, $matches);[/code]But at some point you're really just beating a dead horse. Which way is easier? To me, hands-down your way (I just cooked this one up as a "devil's advocate" counter example, plus regex is FUN!). When I scrape things, I do it the way you do:[code]preg_match_all(/'<start tag>.*?<\/end tag>/s', $html, $matches);[/code]As long as it matches the right stuff in polynomial time, I'd say that's a pretty good way to do it.
