How to regex IMG where width >= 300?

Question

How can I get all of the <img>s with a width >= 300?

My markup/code:

$images = <<<END
<img src="/data/img/201108031_023" width="300" height="400" />
<img src="/data/img/201108031_026" width="250" height="300" />
<img src="/data/img/201108031_028" width="400" height="300" />
<img src="/data/img/201108031_032" width="500" height="400" />
...
END;

My attempt:

preg_match_all("/<img(.*?) \/>/",$images,$matches);
print_r($matches);

It's not a good idea to use regex for this.

This works for your specific example, but it has a number of problems because HTML can't be parsed correctly by a regular expression:

"/<img[^>]*width=\"([3-9][0-9]{2}|[1-9][0-9]{3,})\"[^>]*>/"

See it working online: ideone

I'd suggest you look for an HTML parser instead.

If this were literally the only html to scan, wouldn't a parser be a bit heavy? – Jared Farrish Nov 03 '11 at 23:21
Ok, thanks mark, this is the best way for regex, and I will try to use html parser. – yuli chika Nov 03 '11 at 23:41
