This question already has an answer here:

• RegEx match open tags except XHTML self-contained tags 34 answers

So I'm building a simple HTML scrapper, in the text there are some images for the symbols and what I need is to get the src of this img tags, but keep them in the same place as the img tags where in the text.

--question rewritten due to me being asking the wrong thing.

Since you're using DOM parser so you can extract image's src attribute in a variable. After that use following code:

$imgsrc = '/Handlers/Image.ashx?size=small&name=3&type=symbol';
$url = parse_url($imgsrc);
$query = htmlspecialchars_decode($url['query']);
parse_str($query, $arr);
echo $arr['name'] . "
"; // prints 3
