[RESOLVED] get XML IsValid rest response

jrough

I'm trying to get the response IsValid item. It seems like it should work but I'm getting no response and the code works before I added this line:
if ($parsed_xml->Items->Request->IsValid['True'])

$request = file_get_contents("http://free.apisigning.com/onca/xml?".$allparameter);
 $parsed_xml = simplexml_load_string($request);

if ($parsed_xml->Items->Request->IsValid['True']){		    

$result= $parsed_xml->Items->Item->ItemAttributes->ProductGroup;
var_dump($result);

$result= (string) $result;
var_dump($result);
}

here is the XML returned from the request. It should be something like ["Items"]["Request"]["IsValid"] See after the 13th object

If it's an object reference (object(SimpleXMLElement)#14) then would it not be ->IsValid? And since the top level of that structure is reported to be an array, would it not be ['Items']?

jrough

I tried this
if ($parsed_xml->IsValid['Items']{
.....
}
and it didn't work.
I was trying to understand the array.
Is it an associative array of 2?
The first array is the attributes of the request with 8 values.
The product number, the account number and so forth.
The second array (2) is attributes of the response . Since its an xML object I thought maybe you could transverse the nodes like
items->request->isValid someway? I guess you are trying to get it through the array but I'm not exactly sure how the array is structured to get the "true" value out of it?
I just did array_values($parsed_xml) and I got an error, it said "the argument should be an array" so I think the xml result is not an array? I think it is an xml object and so I might need Xpath but I was able to get the product group this way,
$result= $parsed_xml->Items->Item->ItemAttributes->ProductGroup;
so all I need is to check whether the response was valid or not in my script. Any other ideas?

The thing you dumped to produce the structure you posted was an array. It has two elements, named "OperationRequest" and "Items". The "Items" element is an object, with properties named "Request", "Item", and "ItemAttributes". The "Request" property is also an object, with its own properties: "IsValid" and "ItemLookupRequest". The former is a string, with the value "True".

Assuming that what you dumped was $parsed_xml->Items->Item->ItemAttributes->ProductGroup (because that's what appears in the code you posted), then to get that "True" value the full expression would be

$parsed_xml->Items->Item->ItemAttributes->ProductGroup['Items']->Request->IsValid

I never found much use for SimpleXML, myself; the standard [man]DOM[/man] interface is quite adequate (and doesn't feel as kludgy).

Either way, there is also the option of using XPath to traverse the XML structure - certainly DOM gives that option and I believe SimpleXML does as well.

Thanks, very much I got it through trial and error.
$parsed_xml->Items->IsValid ="True".
So it just had to point to the name of the 2nd array then the attribute I wanted.
