What is the result you're looking for? A list of the %count's keys, or a
list of %count's values (each of which is a hash)? If the former, I don't
believe you can do that with the built-in vmethods. If the latter, try
this:
[% popularshows = {
horror => {
count => {
'1' => {
name => 'scary movie 3',
cost => '10',
},
'2' => {
name => 'Knife Attack',
cost => '9',
},
'3' => {
name => 'Frankenstein',
cost => '10',
},
},
},
};
FOREACH val IN popularshows.horror.count.values.sort('name');
val.name _ "\n";
END %]
