[Cedarvalley] storing a hash in a list...

[Aaron Thompson]

Thanks Steve,

 I was just going to post a solution I came up with when I read
 this message... 

 ...
 my $count = 0;
 for $url (@rss){
   ... building %rss_data
   %{$web_data[$count]} = %rss_data;
   $count++
 }#rof
 ...

 Thanks for the idea - I tried it and it works well.
 
 I like your solution better ;) I'm going to re-write my loop and
 get rid of the iterator.
