php - How to parse xml output

I want to get the content text of an xml output. How do I parse this in php? Please see code below.

<xml>
  <ToUserName><![CDATA[toUser]]></ToUserName>
  <FromUserName><![CDATA[fromUser]]></FromUserName>
  <CreateTime>1348831860</CreateTime>
  <MsgType><![CDATA[text]]></MsgType>
  <Content><![CDATA[this is a test]]></Content>
  <MsgId>1234567890123456</MsgId>
</xml>

Solution:

Try this :

$x = '<xml>
         <ToUserName><![CDATA[toUser]]></ToUserName>
         <FromUserName><![CDATA[fromUser]]></FromUserName>
         <CreateTime>1348831860</CreateTime>
         <MsgType><![CDATA[text]]></MsgType>
         <Content><![CDATA[this is a test]]></Content>
         <MsgId>1234567890123456</MsgId>
    </xml>';

$xml = simplexml_load_string($x) or die("Error: Cannot create object");

print_r($xml);
