Templates and hash arrays?

packetstormer has asked for the wisdom of the Perl Monks concerning the following question:

Hello,

I am really struggling to extract the correct information in perl templates. A Dumper file is below and I simply want to extract the value of the e2eventname key but I can't. The whole array of hashes thing is melting my brain!
I have tried the loop below (and many other variations) but no joy.

[% FOREACH element IN e2event %]
[% element.e2eventname %]
[% END %]

Would anyone know?

$VAR1 = {
'e2event' => [
{
'e2eventprovidername' => 'XYT',
'e2eventdescription' => 'All the latest football news.',
'e2eventstart' => '1315919400',
'e2eventservicename' => '103 - XYT',
'e2eventcurrenttime' => '1315922112.7',
'e2eventremaining' => '588',
'e2eventname' => 'The Football Show',
'e2eventtitle' => 'The Football Show',
'e2eventduration' => '3300',
'e2eventid' => '1237',
'e2eventservicereference' => '1:0:1:2585:7FB:2:11A0000:0:0:0::103 - XY
+T'
},
{
'e2eventprovidername' => 'XYT',
'e2eventdescription' => 'All the new shows.
'e2eventstart' => '1315922700',
'e2eventservicename' => '103 - XYT',
'e2eventcurrenttime' => '1315922112.99',
'e2eventremaining' => '1800',
'e2eventname' => 'News',
'e2eventtitle' => 'News',
'e2eventduration' => '1800',
'e2eventid' => '1657',
'e2eventservicereference' => '1:0:1:2585:7FB:2:11A0000:0:0:0::103 - XY
+T'
}
]
};

Think normal 'for' loop: `for my $element (@e2event) { print $element->{e2eventname}; }` [download] Note: NOT `$e2event->{e2eventname}`	[reply] [d/l] [select]

Hi, I actually had a type in my first post the I have fixed, I should have read exactly as you say - but that doesn't work!	[reply]

OK - I assumed that the e2event in your foreach was the e2event value from the $VAR1 dumped. `[% FOREACH element IN VAR1.e2event %] [% element.e2eventname %] [% END %]` [download] Replace VAR1 with the actual variable you dumped. To see how the template sees your variable: `[% USE Dumper indent=2 %] [% Dumper.dump(some_variable) %]` [download]	[reply] [d/l] [select]
