parsing xml of wikipedia api

[etrader]

I tried to parse wikipedia xml api by different methods, but I was unsuccessful  :'( Even the curl method did not work

    $url = "http://en.wikipedia.org/w/api.php?action=query&prop=revisions&titles=Wikipedia&rvprop=timestamp|content";
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_HTTPGET, TRUE);
    curl_setopt($ch, CURLOPT_POST, FALSE);
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_NOBODY, FALSE);
    curl_setopt($ch, CURLOPT_VERBOSE, FALSE);
    curl_setopt($ch, CURLOPT_REFERER, "");
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
    curl_setopt($ch, CURLOPT_MAXREDIRS, 4);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.1; he; rv:1.9.2. Gecko/20100722 Firefox/3.6.8");
    $page = curl_exec($ch);
    $xml = simplexml_load_string($page);
print_r($xml);

You need to add "format=xml" to your api query.  The wikipedia api default format is xmlfm which is actually just an html representation of the xml, rather than the xml itself.
