SimpleXML: Working with XML containing namespaces

Question

I am trying to get to the geo information off the google-picasa API. This is the original XML:

  
    35         


        

Answer 1

This is how I did it without using xpath:

$georss = $photo->children('http://www.georss.org/georss');
$coords;
if($georss->count()>0) {
    $gml = $georss->children('http://www.opengis.net/gml');
    if($gml->count()>0) {
        if(isset($gml->Point->pos)) {
            $coords = $gml->Point->pos;
        }
    }
}
