Hey Lee, what are the Twitter usernames (or RSS feeds?) Any clues in the XML of the feed?

Hi Lee, it's the URL for Google (source link) in the last tweet/item. It contains an unescaped ampersand &, which has invalided the XML document.

Either Google or Twitter should encode their XML entities properly.

For now, only thing I can think of is either reduce the number of tweets by 1 (so the last one drops off), or do some new tweets (so the last one drops off) ... after that, don't tweet from Google (until they've sorted this out).

OR ... write some RegEx-based RSS parser? (Which is a truly awful idea!) ;-P

Cheers, Lee.

Wow.
Only seen this thread in my RSS reader this morning and it looks like it has kinda been solved already.
Do I need to do any fixes to my codebase or not?

Warren :)

@Warren, no problem - happy to help. It's not your code, no need to worry.

@Lee, just want to confirm which package you are using... Warren's Twitter for Umbraco or your own Simple Tweets? As I believe Warren's code is using the Twitter API XML and yours is using the RSS feed ... and as far as I can tell, this entity name issue should only effect the RSS feed ... if that makes sense?

Cheers, Lee.
