Anyone ever done HTML validation of an arbitrary piece of HTML within  
their RoR app.? Any gems/plugins that would work? Would Hpricot do the  
trick?

Thanks,  
Wes

Are you perchance looking for something like  
[GitHub - wr0ngway/assert\_valid\_markup: Fork of assert\_valid\_markup, sped up by using xmllint locally rather than hitting w3c service](http://github.com/wr0ngway/assert_valid_markup/tree/master) ? I’ve  
never tried that, but I plan to experiment with putting it into my  
automated specs if it works well.

Here’s my old crack at it. Probably newer code bases that do a better  
job.

BTW, assert\_valid\_markup looks to be aimed at functional tests and is  
about  
the HTML being standards compliant.
