How do I create variables from XML data in PHP?

Question

Been trying to figure this out for a short while now but having now luck, for example I have an external xml document like this:

&         


        

Answer 1

$dom = new DOMDocument;
    $dom->loadXML('a'); //your string here 
    //$dom->loadXML(file_get_contents($file_with_pxml)); - from file
    $position = $dom->getElementsByTagName('position');
    for ($i=0; $i<$position->length; $i++)
    {
      $item = $position->item($i);
      ${$item->nodeValue} = $item->nodeValue;//$$item->nodeValue = $item->nodeValue;
    }

But as I know - you can't create variable with dash in name in PHP
