[xml] parsing html with libxml2

[JASON JESSO <jesso1607 rogers com>]

I have saved an html page to a file from my browser. 
When I parse the html with libxml2 (python) a get a
lot of html parser errors.

I looked at the html document and there are a number
of mismatched tags and the sort.

I tried several web browsers and they all have no
problem with it.

Why is that?
