Windows IE7 will not accept bad XML in feeds
In a piece posted on Thursday, the RSS Team at Microsoft warns that the RSS function within the new version of Internet Explorer (IE7) will not accept badly-formed XML. “Our years of experience with HTML in Internet Explorer have taught us the long-term pain that results from being too liberal with what you accept from others. Hence, we’ve adopted the following overriding principle for IE 7 and [the] RSS platform in Windows Vista: We will only support feeds that are well-formed XML.”
When viewing a feed that doesn’t validate as correct XML, IE7 will flag it (and highlight the error, just like we do today for generically bad XML feeds ~ so feed publishers can see what’s going on). When the platform downloads a feed with errors during regular updates, it will discard that update, and will try again at the next scheduled download (so feeds with temporary errors won’t be permanently affected).
Niall Kennedy picks up this point on his blog : “I think it is a good move and saves a lot of development headaches. Feed publishers should periodically check their feeds using tools such as Feed Validator to discover any potential problems and evaluate some of problems revealed by warning messages. Errors in your feed might result in your message not being delivered to your readers.”
