I've got the regex doing what I want, but it's still open to the client
breaking it.
I need to try and extract all text, including html tags, between the first
opening <p> and the first closing </p>.
So from:
<p>I want this paragraph. <b>Including me</b></p><p>But not me</p>
I want:
I want this paragraph. <b>Including me</b>
I have gotten this far:
/<p>([^<]+)<\/p>/
but of course this will not work if any html tag is nested between the p
tags. I've tried adding extra char classes after the one already there, but
it doesn't work. Am I missing something simple here? Any help would be very
much appreciated.
Does anyone know of a site where they have solutions to common regex
problems, something other than the basic tutorials I keep finding?
Thanks
Ade

The assumption (note: assumption) would be that any href's you get would be
URL Encoded so you wouldn't have an issue with " or ' in the URL. Then you
could justifiably use either (typo) to close the string (although it's VERY
bad)
Remember, Regexes can only catch MOST of the cases and not all. Don't even
attempt to catch them all... If there is an error, you fix that one, and
move on. Trying to make a regex that's a be all and end all regex almost
never works.
