A customizable diff tool that can produce report (in XML, HTML)

Question

I want to provide a diff report for a non regression test. My program is Java based but I did not found any API filling my needs.

So I'm using an external tool (CSDiff) that take 2 files as arguments and return an HTML report. That's nice and easy to setup.

Now the only problem I have is that the HTML report needs some tweaks to be used and I am messing around with the report, trying to transform it into something different (hidding some parts, changing the style, ...)

Does someone know a diff tools that has a powerful command line support, allowing custom report to be generated ? Nice report options would be 2 panes view, regexp filtering, easy styling options... something like the vim diff view in html would be great.

I've already read stuff about diff tools in stackoverflow but I don't find the stuff I'm looking for.

• Free diff tool that is configurable?
• Need a Java and Javascript diff tool written in Java

Many Thanks
