如何获取curl响应以获取php中的特定标签？

Question

Here my code is,

$ch = curl_init();     
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$response = curl_exec($ch);
curl_close ($ch);
print_r($response);

I got response like this

<?xml version="1.0" encoding="UTF-8"?>
    <rsp stat="ok">
    <mediaid>af11zj</mediaid>
    <mediaurl>http://yfrog.com/af11zj</mediaurl>
    </rsp>

How to get that mediaurl ? Any one help me? Thanks.

Assume you have the response XML in $response :

<?php 
    $obj = simplexml_load_string($response);
    $mediaurl = (string) $obj->mediaurl;
?>
