Parser crashes with SGMLParseError on valid feed #226

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
1. Try parsing this feed (feed content attached in case the feed changes):
 http://allastrology.blogspot.com/feeds/posts/default

2. I expect feedparser to parse it correctly. But I get an exception instead. 

3. FeedValidator says the feed is valid:
http://feedvalidator.org/check.cgi?url=http://allastrology.blogspot.com/feeds/po
sts/default

4. SimplePie parses it as well:

ault

5. Here is the stack trace I get from feedparser:

A few more feeds that break with the same exception, and all of them are 
considered valid by feedvalidator:

This error is being caused by a <!DOCTYPE> declaration in the content. I've 
attached a sample document that succinctly demonstrates the problem.
