[PHP] Extracting images from HTML using PHP5

I was working on some template modification of this blog, when I dediced to make a php image extractor function. I don't love to use big class with thousend of code lines to parse html.

Looking on PHP5 core it seems to be some DOM function available really usefull to parse html document easly. Using DOMXPath class and DOMElement::getAttribute function you'll need just some beet line of code to extract the needed html string.

The easiest way to explain it, is write the code :-)

<?php
  $myVar = "Ciao <br /><img src=\"11.jpg\" alt=\"foto\" /><br /><img src=\"12.jpg\" alt=\"foto\" />";
 
  $doc = new DOMDocument;
  $doc->loadHTML($myVar);
 
  $xpath = new DOMXPath($doc);
 
  $nodo = $xpath->query('//img[@src]');
    foreach ($nodo as $nodo){
    $imgsrc = $nodo->getAttribute('src');
    echo "<img src=\"".$imgsrc."\" alt=\"myMagicImage\" />";
  }
?>

Short and sweety, isn't it? :-)
