Can't parse XML response

I need help with the following xml response below:

1) Need code to assign each element as variable->$value (ie. returnCode = $returnCode)
2) Detect if element exists (ie. <olps>). I thought this would work for element detection but it does not.

                   if ( strstr($client->response, "<olps>" ) ) { echo "olps detected"; }

Running PHP 5.1.6 (cli)

Here is the response below in code section when I do:

echo '<h2>Response</h2>';
echo '<pre>' . htmlspecialchars($client->response, ENT_QUOTES) . '</pre>';

Are you using nusoap? If you do this:

$result = $client->call(...

... then the $result variable should contain what you need. Do this:

var_dump($result);

Post the result here if you need more help.

Yes, am using NUSOAP. I did var_dump($result) and it's a TON of data returned in arrays (2 pages). How can i access those elements now? and do my detection?

Output this first:

var_dump(array_keys($result));

Then you get the array keys on the first level only. Is 'returnCode' and 'olps' there? If not, which keys do you get? If 'olps' is there, you can access data within it like this:

$startDate = $result['olps']['startDate'];

Yes, they are there.

I'm gettting NULL for both of your examples.

Attached is the output of var_dump($result) which looks messy.

It looks like this is a dump of the entire client object, not the result... did you do this:

$return = $client->call(... your soap call here );
var_dump($return);

It looks like you did just:

$return = $client;
var_dump($return);

...or

var_dump($client);

I wrote "$return" when I meant "$result", sorry if that was confusing. The point is that you must fetch the result of the soap call.

Looks like that did the trick. Here is the output now:

array(4) { ["correlationData"]=>  string(15) "CD4A08261F24496" ["etailId"]=>  string(1) "0" ["returnCode"]=>  string(2) "01" ["olps"]=>  array(6) { ["prescreenId"]=>  string(12) "874800000000" ["prescreenInd"]=>  string(1) "O" ["startDate"]=>  string(8) "20090511" ["expirationDate"]=>  string(8) "20090908" ["purgeDate"]=>  string(8) "20090908" ["creditLimit"]=>  string(4) "2500" } }

returnCode = 01
olps = Array
OLPS detected!

Let me ask you, if I am calling the $client->call SOAP object earlier in the script then put $result = $client->call(...etc) does this mean I am calling the object twice, hence hitting their web-service twice...?
$result = $client->call('themethodhere', $data, $namespace);
var_dump($result);
 
 $returnCode = $result['returnCode'];
 echo "<br>returnCode = $returnCode";
 
 $olps = $result['olps'];
 echo "<br>olps = $olps";
 
 if ($olps) { echo "<br>OLPS detected!"; }

Yes. You should probably only do it once.
