preg_match_all problem

jcaudill

Good morning,

I'm trying to extract any text in between italic html tags on a web page. So, I've written an expression:

preg_match_all('/<i>([^"]*)<\/i>/is',$data,$bullets);

Problem is, if the text contains quotes then the regular expression gets busted. I've tried (.*) but that gives me all kinds of HTML garbage. Any ideas?

Thanks in advance.

Before sending $data to preg_match_all, pass it through addslashes() first, so that the quotes will be escaped.

No dice :-/

See, the " would still be there. So I just changed the code to:

preg_match_all('/<i>([^"]*)</i>/is',$data,$bullets);

Works like a champ. Now I'm having a problem figuring out how to isolate a pretty specific section of code, I need to find anything in between a font tag with the font tag being like:

I NEED THIS

I bet this ones easy, and I can get it to work up until the color attribute and it bombs. Here's what I have:

/<font face="[^"]" color="[^"]" size="3"*><b[^>]*>([^"]+)<\/b><\/font>/is

My question is: if you're trying to get text between italic tags, what do " characters have to do with it in the first place? Did I miss something?

preg_match_all('/<i>((?:(?!<\/i>).)*)<\/i>/is', $data, $bullets);

will return all the text between each pair of / tags. (PS: I recommend using

 instead of [php ] when regexps are at issue; vBulletin mangles them when it's syntax-highlighting the things. You'll notice how your two italic-stripping preg_match_all()s look exactly the same.)

The honest answer is nothing. It's me who doesn't understand regex like I'd like to.
