A good tool to validate your files using w3c validator. Take care of one thing that you should get a local copy of w3c validator otherwise if you process multiple files using this module then your IP may get blocked by w3c. This has happened with me.
Nice module. I used it to clean out the style elements from 100+ HTML files and it worked like a charm, just add rules in %rules and you're done :)
Very nice module. Thanks for this :)
This is just too good. We use this in our company's product and it's very helpful for dealing with excel files. Thanks to the author :)
