Hello I have script that returns XML...I tried to covert it into an array. It works mostly, but when I try to loop part of the array since the array can have multiple items it seems as though the array is broken up in to 4 parts...

So here is what I have..When I do a var_dump on the original data sent back I get this

object(SimpleXMLElement)#27 (3) {
  ["@attributes"]=>
  array(3) {
    ["timestamp"]=>
    string(25) "2014-03-19T15:31:55-05:00"
    ["payloadID"]=>
    string(81) "2014-03-19T15:31:55-05:00.WC@vOmAl/S8yzyHUc6egkAxb8Xi0co= .9123001443@42374153835"

        }
      }
    }
  }
}

Open in new window


After I get this code I convert it to an array using

$array = json_decode(json_encode((array) $xml), 1);
$array = array($xml->getName() => $array);

Open in new window



I can then pull out each variable...But the problem lines when I get to

foreach($array['cXML']['Message']['PunchOutOrderMessage']['ItemIn']  as $item)
{
}

Open in new window


if I do a print_r($item); inside the loop it returns 4 separate arrays..Any ideas why it is not one array and how I can fix this?

Thanks!

Please post the original XML document.  You can obscure passwords or any private information like that, but I would need the structure (and tag names) to be intact.  I'll show you how to parse it.  Thanks, ~Ray

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

This does work, but I already had this working..What I am trying to do is loop through the items...

I added
$array = json_decode(json_encode((array)$item), TRUE);
print_r($item);

Open in new window


to the end of your code to convert it into an array...But I still cant loop through 'ItemIn' I am trying to do a foreach loop but it errors out each time..

Thanks

it errors out each time
Exactly what output do you get?
loop through the items
But there is only one item!  It's an object - a data structure with stuff inside it.  Are you aiming to get the contents of the data structure?  Or is the test data missing some other items?  Please clarify and I'll try to get you a better code example, thanks.

Actually I was able to get it to work by

oreach($item as $itm)
{
echo $itm->ItemID[0]->SupplierPartID;
}

Open in new window


But in the xml there is a ['@attributes'] and I am not sure how to handle this?

I was trying

echo $itm->ItemDetail[0]->Extrinsic[5]->@attributes->name;

Open in new window


but i receive and error..

This turns into a mess when you get to the Extrinsic components.  Do you have any influence over the format of the XML document?  If so, it might make a lot of sense to wrap the Extrinsic elements in an <Extrinsics> tag.

Still working it, but I get the feeling that it's not a straightforward solution!

This seems to work.  Usually var_dump() is your friend, but it didn't produce what I expected here.  Moving parts to extract the Extrinsic components start at line 60.  

I reformatted the XML document a little bit so I could see what I was working with, since var_dump() was not as helpful as I hoped.  The reformatting has no effect on the execution of the script.
