Highlight text diff on client?

Question

I want to compare 2 text values on a web page and highlight the differences. Can I do this client-side, preferably with jQuery or Prototype?

Answer 1

This diff-patch-match library appears to do a really good job:

The project has JavaScript, C#, C++, Python, and Java implementations that all do the same thing.
