Accessing data from XML

[abosaleh]

Right, so this is my first day using XML. I'm not creating the XML, someone is sending me a URL and I need to do something with it using PHP. This is what the XML structure looks like:\[code\]<response><query id="1"><results> <item> <id>GZ7w39jpqwo</id> <rank>1</rank> <explanation>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla a massa lectus, sed convallis sapien. Curabitur sem mauris, ullamcorper ut. </explanation> </item> <item> <id>hfMNRUAwLVM</id> <rank>2</rank> <explanation>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla a massa lectus, sed convallis sapien. Curabitur sem mauris, ullamcorper ut. </explanation> </item> <item> <id>I_cxElavpS8</id> <rank>3</rank> <explanation>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla a massa lectus, sed convallis sapien. Curabitur sem mauris, ullamcorper ut. </explanation> </item></results></query></response>\[/code\]So, yeah, this is what I've figured out so far...\[code\]$url = "http://www.MyURL.blah";$string = file_get_contents($url);$xml = simplexml_load_string($string);echo $xml->getName();\[/code\]This echoes the word 'response'. Yay, go me! So now how the hell do you get the id, rank, and explanation of each item? I only posted 3 items above. There'll actually be about 50.
