XML validator

["Rodney Boyd" <rodney.neil.boyd@gmail.com>]

Hi,

Can anyone recommend an XML validator that validates against W3C
schemas and can be run in batch mode? It doesn't have to be free, but
that would be a bonus. I'm familiar with xsv and xmllint, but am
looking for other options.

Thanks!
