Introduction

Daisy Diff is a Java library that diffs (compares) HTML files. It highlights added and removed words and annotates changes to the styling. (Examples)

This project was a Google Summer of Code project for DaisyCMS where it's actively used for diffing HTML content. Development of a stand-alone library is continued here.

Features

• Works with badly formed HTML that can be found "in the wild".
• The diffing is more specialized in HTML than XML tree differs. Changing part of a text node will not cause the entire node to be changed.
• In addition to the default visual diff, HTML source can be diffed coherently.
• Provides easy to understand descriptions of the changes.
• Allow easy browsing of the modifications through keyboard shortcuts.

Download

A stand-alone library is available in the download section. To embed Daisy Diff in your application you can checkout the SVN project.
