Accessing perl array

Hi all,

How do I access the 'Name' field of the array?
I am using Data::Dumper, this is the output when I use the following (read from XML):

print Data::Dumper($tree);

Code:

[
          {
            'desc' => {},
            'content' => [
                           {
                             'desc' => {
                                           'Name' => 'John',
                                           'Date' => 'September 2006',
                                           'Color' => 'Blue',
                                           'Success' => 'TRUE',
                                           'TimeStamp' => '02-SEP-06 07:30 PM',
                                           'Version' => '.25'
                                         },
                             'text' => [],
                             'name' => 'Application'
                           }
                        ]
           }
]

Thanks in advance,

I am just guessing a bit, but I would try with:

Code:

$tree[0]{'content'}[0]{'desc'}{'Name'}

I might be missing a -> because its late and I am tired hehehhe

Still, I hope this is useful!
Cheers!

Actually, the (2nd) 'desc' hash key is at the same level as 'Name', so drop that bit.

Hi chrism01... be aware that there is a 'name' key and a 'Name' key. I think that rjcrews wanted the second one (because he wrote it with an capitalized). So the 'desc' is necesary if rjcrews wants to access "John". And you would be right that it is superfluous if he wants to access "Application".
I think it is the first case, but thats not for me to say

Either way, I am glad that I didnt missed any -> heheheheh

Cheers!

Good call. If it was me I'd make an effort to have var/key names that differed more...
Maintaining that sort of stuff would be b*tch.

Thx for the reply...helped a ton. The [0] part was what I had wrong.
