Dear community, I have an xml file which was converted into a hash variable via XML::Simple.
use XML::Simple qw(:strict); $config = XMLin('config.xml', KeyAttr => {item=>'filename'}, ForceArra +y => ['item']);
My xml file looks like:
<?xml version="1.0" encoding="UTF-8"?> <config> <item> <id>0</id> <filename>AMEX</filename> <destination_dir>test</destination_dir> </item> <item> <id>1</id> <filename>bla</filename> <destination_dir>test1</destination_dir> </item> <item> <id>2</id> <filename>alb</filename> <destination_dir>test2</destination_dir> </item> </config>

the problem is, that I must have 2 possibilities to access the information in the <item>

The first case is to access a single item by its filename like: print $config->{item}{"bla"}->{destination_dir};
It works fine!
The second case ist, to go through the whole config (item after item) and here I need to access each single item by an index like:
for (my $i = 0; $i < $theNumberOfItems; $i++) { print $config->{item}[$i]->{destination_dir}; }

But if I try this, I get an error: Not an ARRAY reference at test.pl line 18.

I try to make the <id> to another key: $config = XMLin('config.xml', KeyAttr => {item=>'filename', item=>'id'}, ForceArray => [ 'item']); and then to access like this:
for (my $i = 0; $i < $theNumberOfItems; $i++) { print $config->{item}{$i}->{destination_dir}; }

It workes fine, but now the access via filename is impossible. I suspect, that it is not allowed to have two of KeyAttr and the last one overwrites the filename...

Is there any possibility to access nevertheless on both ways?

Thanks a lot!
Dimitri
