How big is too large? My largest xml file is about 20 mbs... I'm a little unclear on how to programatically save everything to the hash and then look it up... I haven't worked with hashes that much in Perl yet. So, the first time I loop through the xml to find the comments, I store each comment as a new entry in the %comments array, right? Something like this? 
...
my $commentText = $date . $author . $content;
my %comments = (
  $posturl => [$commentText]
)
...

[download]

I can see that working for one comment--would a second comment then overwrite the first in the array or would it add automatically? Would I need to use push or something?

Then, during the second pass, how exactly would I reference the keyed array?

Sorry for all the newbie questions... Thanks!
