Parsing an HTTP response

subscribe77

Hi,

I'm new to PHP and I would like to get some help on parsing a response sent from a XLink server.

When the following script runs...
<b>$fp = fsockopen($remote_server, 80);

if ($fp)
{
	// Send HTTP request
	fputs($fp, $header . $request);</b>

a response is sent back and stored in a variable called response. The response looks like this:

<b>HTTP/1.0 200 OK
Content-Type: text/xml
Date: Tue, 27 Jan 2004 21:21:23 GMT
Server: Apache Tomcat/4.0.6 (HTTP/1.1 Connector)

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE response SYSTEM "http://xlink-server.com/dtd/response.dtd" >
<response requestid="">
<header>
<sender>
....etc...</b>

My goal is to parse the XML portion of the response but the "HTTP response" header is causing me problem. What kind of parse or response manipulation functions in PHP could I use to remove the first 4-5 lines of the response? Or how can I remove that header portion and leave out just the xml portion of the response?

I tried the following while-loop script to search for "<?xml" in the response but got an error:

                          <b>$found = false ;
	 while (!feof($fp)) {
	  $data = fgets($fp, 128);
	  if (!$found) {
		$x = $data.substr($data,0,4) ;
	  	echo $data.substr($data,2,4);
		if ($x == '<?xml')
			$found = true ;
		echo $found ;
	 }</b>

Also, I'm using "xml_paser_free" to parse the xml repsonse. I know that the xml parser works if I don't have the HTTP response header.

Thanks in advance for any tip or help.
