Convert XML Into Usable Variables

[ideffect]

Hi,

I'm working on a purchase system integrated with PayPal's Website Payment Pro System (paypal's version of a merchant account). I've been able to verify payments and get a return response from their system but I am unsure how to extract the response into either an array or separate variables.

The return response is XML SOAP coding. Here is the response...

<?xml version="1.0" encoding="UTF-8"?>
	<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" xmlns:xsd="http://www.w3.org/1999/XMLSchema" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:cc="urn:ebay:apis:CoreComponentTypes" xmlns:wsu="http://schemas.xmlsoap.org/ws/2002/07/utility" xmlns:saml="urn:oasis:names:tc:SAML:1.0:assertion" xmlns:ds="http://www.w3.org/2000/09/xmldsig#" xmlns:wsse="http://schemas.xmlsoap.org/ws/2002/12/secext" xmlns:ebl="urn:ebay:apis:eBLBaseComponents" xmlns:ns="urn:ebay:api:PayPalAPI">

			</DoDirectPaymentResponse>
		</SOAP-ENV:Body>
	</SOAP-ENV:Envelope>

I've been able to display the results with the following code...

$xml = simplexml_load_string($xml);
echo "<pre>";
print_r ($xml);
echo "</pre>";

I am assuming I need a XML Parser but not being familiar with XML, I don't know how to continue. Any help is greatly appreciated!
Thank you.

SimpleXML is an XML parser, so you've already done that. How you use the PHP object that results is up to you (further study of the [man]SimpleXML[/man] sections of the manual should give you some indiciations about how to proceed from there).

Thanks for the reply. I forgot to mention I tried to use the code found in the PHP manual. This is what I am referring to since I no longer have what I used.

foreach ($xml->movie as $movie) {
   echo $movie->plot, '<br />';
}

I'm going to try to work with that again now that I have a clear head but if you can show me an example of how to manipulate the above data or give me an address of a tutorial, that would really help me . I'm only interested in the second half of the xml data from Timestamp and down.

Thanks.

I have no idea what to tell you about how to manipulate the data because I have no idea how you want to manipulate the data. Anything I said would have to be so generic it would be just repeating what is in the manual.

In other words: you have to know how you want to manipulate the data first. Once you get a plan clear in your mind (or on paper, or in a text editor, or whatever), then you can start putting it together out of the bits that are supplied.

And that's called programming.
