You can go for SimpleXML

Answer 2

As SaC said... SimpleXml is probably the easiest answer here.

// assume $xmlstring is the xml you posted

$xml = new SimpleXmlElement($xmlstring);
$urls = $xml->xpath('//PAD_URL');

foreach($urls as $url)
{
  // when used in a string contect $url will be the text value
  echo $url;

  // however its still really the object so for example if you needed te attributes
  $attributes = $url->attributes();

}
