Hello all. I have a problem that I have been bashing my head against the wall on. I have a computed hash with a very complex format (multiple layers deep). I want to be able to pick out a series of values from keys stored in this hash, and would like to be able to store the key names in an array.
For example, the array would contain
my @array = (
'{title}',
'{Rule}{Severity}',
'{Rule}{weight}',
'{Rule}{id}',
'{Rule}{version}',
'{Rule}{title}',
'{Rule}{detailedDescription}{VulnDiscussion}',
'{Rule}{detailedDescription}{Responsibility}',
'{Rule}{detailedDescription}{IAControls}',
'{Rule}{check}{check-content}',
'{Rule}{fixtext}{content}',
);
I would like to later process the array and pull individual results out of the parent hash on the fly, al la:
foreach my $firstKey (sort keys %hashData) {
foreach my $arrayKey (@array) {
print $hashData{$firstKey}$arrayKey;
}
}
With '$hashData{$firstKey}$arrayKey' being treated like '$hashData{$firstKey}{Rule}{detailedDescription}{VulnDiscussion}'.
The problem is that I don't know how deep the array key may get on the fly, and at a certain point can just write a block of code quicker for each item in the array rather than try and make it more malleable. However, I really want to make the configuration (order of items to extract, etc) more, well, configurable, and not have to add a block of code each time the group wants a new piece of data added.
Thanks in advance!
