I'm trying to create a database of World of Warcraft gems. If I go to this page:

http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=purple&searchType=items

And go to View Source in Firefox, I see a tonne of XML data which is exactly what I want. I wrote up this quick script to try and parse some of it:

<?php

$gemUrls = array(
                 'Blue' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=blue&searchType=items',
                 'Red' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=red&searchType=items',
                 'Yellow' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=yellow&searchType=items',
                 'Meta' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=meta&searchType=items',
                 'Green' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=green&searchType=items',
                 'Orange' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=orange&searchType=items',
                 'Purple' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=purple&searchType=items',
                 'Prismatic' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=purple&searchType=items'
                 );


// Get blue gems

$blueGems = file_get_contents($gemUrls['Blue']);

$xml = new SimpleXMLElement($blueGems);

echo $xml->items[0]->item;

?>

But I get a load of errors like this:

Warning: SimpleXMLElement::__construct() [simplexmlelement.--construct]: Entity: line 20: parser error : xmlParseEntityRef: no name in C:\xampp\htdocs\WoW\index.php on line 19

Warning: SimpleXMLElement::__construct() [simplexmlelement.--construct]: if(Browser.iphone && Number(getcookie2("mobIntPageVisits")) < 3 && getcookie2( in C:\xampp\htdocs\WoW\index.php on line 19

I'm not sure what's wrong. I think file_get_contents() is bringing back data that isn't XML, maybe some Javascript files judging by the iPhone parts in the errors.

Is there any way to just get back the XML from that page? Without any HTML or anything?

Thanks :)
