Thanks to all for your commments / suggestions. I've learned a few things about XML during the process. Still much more to learn about it though in my spare time. As this is likely a one-time shot, I'm not sure of the value of getting very deeply involved in this process.

For now, using XML::Simple and Data::Dumper, I have parsed the six bookmark files into one large file filled with URL's. I then took this file, put it in a hash, thereby deleting the duplications, then wrote it out to a file of 'unique' URL's.

My plan now is to convert this file into HTML, then at my leisure, visit each of the sites (if they still exist) and bookmark them. Hmmm.... Maybe LWP::Simple can sort out the dead ones without me visiting each one. Another quest....

Thanks again to all,
Mike
