Getting image with its link by DomDocument

[etrader]

It is easy to get image or link by DomDocument, but I did not find a way to get image with its target link. Imagine a html as

<div class=image>
<a href='http://site.com'><img src='imagelink.jpg'></a>
</div>

How to get both the image link and href?

$dom = new DOMDocument();
@$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
$hrefs = $xpath->evaluate("/html/body//div[@class='image']");
for ($i = 0; $i < $hrefs->length; $i++) {
$href = $hrefs->item($i);

Now to get the image and its href, we need first getElementsByTagName('a') and getElementsByTagName('img') but they do not work inside foreach.

 

What's your idea?

If I were you I would refrain from using DOMDocument it's very unreliable. Please consider using regex instead which is very precise and powerful for parsing documents for example.

 

This piece of code will return the URLs of all the links in the document that surround an image.

 

preg_match_all('#class="image".*?a href='([^']+).*?img src#s', $html, $imglinks);

foreach ($imglinks[1] as $imglink)
    echo $imglink;

Nice idea, but I got an error

PHP Parse error:  syntax error, unexpected '(' in the preg_match_all line

need to escape the single quotes:

 

preg_match_all('#class="image".*?a href=\'([^\']+).*?img src#s', $html, $imglinks);
