Regular Expression for preg_match

Question

I got following String:

ElFTkSuQmCC" alt="" width="auto" height="auto" /></td>
<td style="padding: 10px;">XX,X%</t

And want to have the "XX,X", so i build following regular expression:

/QmCC" alt="" width="auto" height="auto" \/><\/td>\n<td style="padding: 10px;">(.*?)%/

I tested it online and got a match for the XX,X but when i try to execute it in php with following code preg_match_all('/REGEX/',$string,$match);

It didn't match. Do you have any suggestions? The String is definitely in there. var_dump($match) gives me an empty array.

Thank you!

You should use a parser. Regex with HTML/XML will more than likely fail at some point. — chris85, Oct 22 '15 at 12:59

Problem is in the newline. In your regex, there is \n. Use \r\n instead and it will work.

Glad to hear that :) – Martin Heralecký Oct 22 '15 at 13:07

Just a word of caution: that may work in this specific case, but it's better to just make your regexp be newline-unaware by using a modifier to let whitespace or the dot span over any possible newlines. – klaar Oct 22 '15 at 13:10

Considering X as digit in your string:

$pattern = '/(\d{2},\d{1,2})/';

preg_match_all($pattern, $string, $match);

I should've said that the posted string is not the hole String i am really searching in. – PhilipB Oct 22 '15 at 13:27
