Php SimpleXML find specific child node in any level in the parent

Question

I'm using SimpleXML to parse my xml file. I'm looping through it and in each node I need to get value of one specific tag. Here is an example

<node>
    <child1></child1>
    <findme></findme>
    <child2></child2>
</node>
<node>
    <child1>
        <findme></findme>
    </child1>
    <child2></child2>
</node>
<node>
    <child1></child1>
    <child2>
      <another>
            <findme></findme>
      </another>
    </child2>
</node>

In each node I need to get findme tag. But I don't know in which level it can be, all I know is a tagname

Answer 1

The only decision I came up with was to use this recursive function

foreach($xml as $prod){
  ...
  $findme = getNode($prod, 'fabric');
  ...
}

function getNode($obj, $node) {
    if($obj->getName() == $node) { 
        return $obj;
    }
    foreach ($obj->children() as $child) {
        $findme = getNode($child, $node);
        if($findme) return $findme;
    }
}

Also as was suggested in comments we can use DOMDocument class like this:

 $dom = new DOMDocument();
 $dom->LoadXML($xmlStr);
 $nodes = $dom->getElementsByTagName('node');

 foreach($nodes as $node)
 { 
    $findme = $node->getElementsByTagName("findme")->item(0);
    echo $findme->textContent."\r";
 }
