Building an HTML Diff/Patch Algorithm

Question

A description of what I\'m going to accomplish:

• Input 2 (N is not essential) HTML documents.
• Standardize the HTML format
• Diff the two documents

Answer 1

You could start by using beautifulsoup to parse both documents.

Then you have a choice:

• use prettify to render both documents as more or less standardized HTML and diff those.
• compare the parse trees.

The latter allows you to e.g. discard elements that only affect the presentation, not the content. The former is probably easier.
