从HTTP套接字响应获取XML元素的值

Question

I have a controller that sends requests using an HTTP Socket, and gives responses in xml format. I am using cakephp 2.6.
Here is my code to get response body:

    $HttpSocket = new HttpSocket();            
    $response = $HttpSocket->request($request);
    $resulthit = $response->body;

When I try to print the response body, it returns this in my browser:

-2201502101153512eFXcByWLUHvQmYC0EHMn2JVxcpyzozBcek uid dan pwd

But when I look at the source of page, this is what I see:

<? xml version="1.0" ?>
  <PUSH>
   <STATUS>-2</STATUS>
   <SMSCMESSAGEID>20150210133953</SMSCMESSAGEID>
   <GUID>knDlIBuUZf6zixlhbbxxLoxhEUGZTWPD</GUID>
   <MSG>cek uid dan pwd</MSG>
  </PUSH>

How I can get value of XML element above?
I want the STATUS and GUID.

I've already tried:

$xml = new SimpleXMLElement($resulthit);

But I only get an error in return that says

 "String could not be parsed as XML"

Answer 1

You can use the CakePHP Xml class: CakePHP XML class

The reason the code cannot be parsed as XML is because you have < pre > tags surrounding it, Im guessing because you are trying to do debug($something).

At the top of the controller include the XML class:

//First Load the Utility Class
App::uses('Xml', 'Utility');

in the controller action do the following:

$this->autoRender = false;
pr(Xml::toArray(Xml::build($thexmlvariable)));

That way you can test it then you should use the ajax layout (A blank layout).

好吧，最后我得出结论，由于“处理指令目标之前存在空格”，我从Http响应获得的xml无效，我尝试使用有效XML的另一个“虚拟文件响应”，它给出了我想要的。
