If you want to search *all* directories for html files, go for chromatics solution. If on the other hand you wish to search *some* directories for html files I suggest you put your dir/file names in a separate file that you read into an array. Otherwise you will need to put either the the "do's" or the "dont's" in your fetch sub.
I find a separete file more easy to maintain, but thats a matter of taste I guess...
