jTidy cfc (stand alone and CFWheels plugin)
"JTidy is a Java port of HTML Tidy, a HTML syntax checker and pretty printer. Like its non-Java cousin, JTidy can be used as a tool for cleaning up malformed and faulty HTML." More information
I was looking for something to clean up some html for pdf generation using cfdocument and found a jtidy.cfc used by Farcry for returning valid xHTML.
If you weren't familiar, "FarCry Core is a web application framework based on the ColdFusion language. FarCry CMS is a popular content management solution built with FarCry Core."
I reviewed the license and from my understanding of "GNU GPL License v3 (GPL)" I can publish my modification. I added javaloader and did some slight modification of the code. My code changes are here for review and download: jTidy CFC
Implementation is really easy for this version of jTidy with ColdFusion.
Drop the jtidy_cfc folder in your webroot or add cfmapping to it, then invoke the jtidy.cfc and pass in the html you want to return as valid xHTML.
Here is the code for my samples, it take some not valid xhmtl examples and fixes them.

I also created a jTidy CFC plugin for CFWheels.
Very handy. Thanks! I haven't looked into this more but any chance with a little work this could be used as part of unit testing to check code to make sure the html is valid?
