将外部wordpress页面作为XML对象返回

Question

I have a CakePHP site for a client, but with the sites blog run on Wordpress (I just redirect to the WP site for the blog). The client now wants a section of the homepage to pull in a snippet from the blog and I am wondering what is the best way to do this. I am currently trying this...

 function getPosts($feed_url) {

    $content = file_get_contents($feed_url); // get XML string
    $feed_object = new xml($content); // load XML string into object
    $x = new SimpleXmlElement($content); // load XML string into object
}

getPosts("example.com");

The 'file_get_content' is working great and actually pulling in the html but I cannot get that html into xml. My error message is 'String could not be parsed as XML'. Anyone know the best way to go about this?

You may want to use simplexml_load_string directly.

function getPosts($feed_url) {
    $content = file_get_contents($feed_url); // get XML string
    $xml = simplexml_load_string($content); 
    return $xml;
}
