exactly. use the non-greedy "?" with the perl regex's
to have perl match the least amount of characters it can.
preg_match('/<blah(.*?)>/', $text, $matches)
in the case of perl regexp's, you have to specifically
tell the regexp not to be greedy. the "?" regexp modifier
is how you do this. (otherwise, the regexp will try and
match the maximum amount of text that it can, which
usually isnt what you want, since it'll match *eveything*
between "blah" and the last occurance of ">" in the text)
so, in the case of this text:
<blah now>
sasfd asdf asdf
</html>
the greedy will match something like this:
now>
sasfd asdf asdf
</html>
and the non-greedy will match something like this:
now
