getting img src within a link - php

Question

I am having trouble with retrieving the src of an image that is part of a link. For example with this I would like to retrieve the src of the img between the tag.
<img src="http://example.com/picture1234.jpg" id="pic_1234" />
I will need to do this for a couple of the links on the page that are all laid out the same. So what I tried so far is this:
$dom = new DOMDocument;
#$dom->loadHTML($html);
$i = 0;
$links = $dom->getElementsByTagName('a');
//Get images
foreach ($links as $link){
$test = $link->getAttribute('href');
if (strpos($test,'/video') !== false) {
$XV_IMG[$i] = $link->nodeValue;
$i++;
}
}
If the link does not contain an img tag only, but instead it has plain text it will work just fine. Is there any way to get the src?

Answer 1

Just keep using getElementsByTagName on the node like this
foreach ($link->getElementsByTagName('img') as $img) {
$XV_IMG[] = $img->getAttribute('src');
}

Answer 2

try to use preg_match_all
$html= '<img src="http://example.com/picture1234.jpg" id="pic_1234" />
<img src="http://example.com/picture1224.jpg" id="pic_1224" />
<img src="http://example.com/picture1434.jpg" id="pic_1434" />
<img src="http://example.com/picture1554.jpg" id="pic_1554" />
<img src="http://example.com/picture1334.jpg" id="pic_1334" />';
preg_match_all('/<a href="(.*)"><img src="(.*)" id="pic_[0-9]{1,7}" \/><\/a>/i',$html,$out);
unset($out[0]);
unset($out[1]);
print_r($out);
