Today I finally got round to uploading my latest changes to XML::RSS::Tools up to CPAN. By combining bits from Matt's rss-mirror script and HTML::Entities, I've been able to clean up most of the problems with dirty RSS, and deal with some of the defects inherent in XML::RSS.
Soon I shall see what I've done wrong this time...
Until the bug reports come in, it's once less thing on my list of to do list.....
UPDATE
I found a bug. On my Linux boxen you get slightly different output code - resulting in a failed test. I will have to investigate further, expect 0.06 soon.....!
