Question about return XML processing

[EK]

I have a form that I'm posting the contents to a 3rd party data management server via cURL. They return XML to let you know if the data was posted successfully or not. I'm trying to figure out how I can take that return XML and parse the data out of there.

 

<?php

extract($_POST);

 

$url = 'https://www.*domain*.com/DataReceiver';

 

$fields = array(  blah blah blah

);

 

foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }

rtrim($fields_string,'&');

 

$ch = curl_init();

 

curl_setopt($ch,CURLOPT_URL,$url);

curl_setopt($ch,CURLOPT_POST,count($fields));

curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string);

 

$result = curl_exec($ch);

 

 

Now my question is, when the data posts and the XML is returned, how do I capture that? When I don't use cURL and post directly using HTTP POST, I get the XML returned at the exact same address I post to.

 

So to process the XML returned, is this code correct?

 

$xml_feed_url = 'https://www.*domain*.com/DataReceiver';

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $xml_feed_url);

curl_setopt($ch, CURLOPT_HEADER, false);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$xml = curl_exec($ch);

curl_close($ch);

 

I'm kind of at a loss on what to do from this point...

 

Thanks to anyone who takes the time to read and can help!

SimpleXML is a good place to start looking.

Thanks for the suggestion, but I'm getting errors that I can't include files from external domains when I try to use simplexml_load_file. Any other suggestions?

[requinix]

You mean you're getting errors that mention allow_url_fopen? If so then you can't use SimpleXMLElement + a URL. Since cURL apparently works, use that to get the XML then feed it to SimpleXML.

 

If not then what error messages are you getting?

OK got it working now with simplexml_load_file

 

Not sure how to parse the resulting code though. I'm getting something like:

 

[Variable]  => Value [Variable]  => Value [Variable]  => Value [Variable]  => Value

 

Thanks for your help.

Have a look through the basic SimpleXML examples, and if you're having trouble post a sample of the XML itself for us to help you with.

This is in my PHP code:

 

$xml = simplexml_load_file('https://www.....com/...Receiver');

print_r($xml);

 

 

My output looks like this:

 

SimpleXMLElement Object ( [isValidPost] => false [ResponseType] => LeadType_ID_Missing [ResponseDetails] => Lead Type ID (LID) is required, please refer to the post documentation [LeadIdentifier] => 0 [VendorAccountAssigned] => 0 [PendingQCReview] => false [Price] => 0 )

 

My goal is to get variables that I can pass elsewhere. For example I want to get [ResponseType] out so I can pass it in a URL string for example.

 

 

Ex of how I'd like to use the code:

 

header ("Location: nextpage.php?[ResponseType]=$ResponseType")

The examples on the page that I linked to didn't help at all?
