Re: Preg_replace question

I've been down the road of attempting to do this with regular expressions... i'm no expert, but i work with people who are, and it was a nightmare.... given that the following are common/valid href=something.php href = 'something.php' href='something.php' href = "something.php" href="something.php" AND you'll have potentially MANY tags with MANY allowed attributes, it turns into quite a complex regexp really quickly... i decided that I should probably do it all with a parser, or even a char-by-char analysis/state engine, but never got much further...
