Are there any tools out there to compare the structure of 2 web pages?

Question

I receive HTML pages from our creative team, and then use those to build aspx pages. One challenge I frequently face is getting the HTML I spit out to match theirs exactly.

Answer 1

I was thinking on lines of XML Diff since HTML can be represented as an XML Document. The challenge with HTML is that it might not be always well formed. Found one more here showing how to use XMLDiff class.
