Hello perl Monks, I need to check to see if an xml hash element exists so i can create an array to post to variables for "stuff".
It sounds complex, but really its not. I'm sure i'm over-looking something simple.
Here is the gist of it:

I have xml returned to me (using SOAP::Lite) that looks something like this: 

<xml version, encoding & SOAP Envelope header stuff...>
<account>
    <accountId>001</accountId>
    <accountName>Account 001</accountName>
    <asset>    
        <assetId>abcd</assetId>
        <assetName>Asset abcd</assetName>
    </asset>
    <asset>
        <assetId>wxyz</assetId>
        <assetName>Asset wxyz</assetName>
    </asset>
</account>
<account>
    <accountId>001</accountId>
    <accountName>Account 001</accountName>
</account>
</SOAP Envelope stuff...>

As you can see from the xml response, I am being returned account information that may have many or no "assets".
I am trying to perform actions (do stuff) with each 'account' + 'asset' sets.

Ultimately, I need to create an array like this:

for each (asset that exists) 
{
$array = (accountId, accountname, assetId, assetName);

(do stuff with the array);
}

note - the 'accountId' and 'accountName' need to be carried through to each relevant 'asset'.

my script seems to die when it hits the 'account' with no 'asset'.

my $data1 = $xml->XMLin($xmlResponse);
foreach my $account (@{$data1->{'account'}}) {
   
    my $acctName = $account->{'accountName'};
    my $acctId = $account->{'accountId'};
    
    if (defined $account->{'ns1:asset'}) {
        
        our $assetID = $account->{'asset'}->{'assetId'};
        our $assetName = $account->{'asset'}->{'assetName'};
        }
    else { 
        print "\nIt didn't process\n";
    }
}

The out put looks like this:

Bad index while coercing array into hash at c:/temp/parseit.pl line (e
+quivelant of 7 in this case).

Is the 'if (defined...' not doing what i think it should be doing?

Thanks
