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...
