The python guys (they can't be all bad, after all :) have created a DTD called [http://pyxml.sourceforge.net/topics/xbel/|XML Bookmark Exchange Language] which "<i>is a rich interchange
format for "bookmark" data as used by most Internet browsers.</i>"
As I wanted to play with the [cpan://XML::Writer] module and clean up my bookmark files, I ended up whipping up this code. Have fun!
<p><b>Update 2001-11-13</b>: Complete rewrite of the adr2xbel script. It follows a bit more closely the python script found in the PyXML library demos.</p>
