Question

I have a DomDocument, which is impossible to var_dump (it really makes me angry) on which I do :

var_dump($dom->getElementsByTagName('url'));

on a response like this :

<?xml version="1.0" ?>
<rss version="2.0">
  <channel>
      <url>beaute-mode/cheveux/11460--choisir-un-headband</url>
      <title>get_url_article</title>
      <host>myhost</host>
  </channel>
</rss> 

But I got the var_dump echoing : object(DOMNodeList)[262] instead of my raw data (which is an URL).

So my question is pretty simple but how do I get my raw data without being encapsulated in an DomNodeList ?

thanks.

Answer 1

DOMNodeList::item() will give a DOMNode in the DOMNodeList by index. For example, to get the first node in the list:

$dom->getElementsByTagName('url')->item(0)

To get the actual data that the element contains, use code something like this:

if ($node = $dom->getElementsByTagName('url')->item(0)) {
  $url = $node->nodeValue;
} else {
  // Element does not exist, handle error here
}
