How to do strict parsing

[Raj]

I just want to know if my html is well formed or not.


s = '<p>ruby on rails</div>'
Nokogiri::HTML.parse(s,nil,nil,0)


I was expecting the parse method to blow up or to raise some kind of
exception.

What is the best way to find out if an html page is well formed ( all
the tags are closed) or not using nokogiri?

The problem is that it doesn't know what you mean by "strict". Is
that HTML 3, HTML 4, or HTML 4.01?

Your best bet is to check the "errors" array on the document. That
will tell you if it decided to correct anything:

doc = Nokogiri::HTML('<p>ruby on rails</div>')
raise "invalid html" unless doc.errors.empty?
