Validate the HTML itself

[msgilligan]

It would be nice if this tool could also validate the HTML.

You may be able to do this with JSoup directly, it looks like it can report parser errors.

I also found this Stack Overflow post that shows how to use JSoup to parse output from the w3c validator:

another option could be the (very old) jtidy: http://jtidy.sourceforge.net/howto.html

Doing a quick check I could not find a validation opportunity with JSoup. However, there seems to be a revived version of JTidy on GitHub: https://github.com/jtidy/jtidy which has released its latest version in 2023.
