Description Olivier Thereaux 2007-03-22 02:03:44 UTC 
Quite often users of the validator get puzzled at "there is no such attribute oNClick", because of case-sensitivity of XHTML, or other such typos.

A useful feature would be to append to the message
there is no attribute "onMouseover"
a fuzzy-match saying: 
did you mean "onmouseover?
Comment 1 Olivier Thereaux 2007-03-22 02:07:22 UTC 
What that would imply on the technical side is:
* a dictionary of all elements and attributes, from the DTD of the document type used
* a fuzzy-matching engine comparing the offending element/attribute with the dictionary

The former is relatively easy to build. Anyone knows of a good implementation of the latter, in CPAN if possible?

Maybe this or some of the other modules it mentions?

String::Approx is not bad. I got some confusing results at frist but after a bit of wrangling I find it reasonably effective.
