So all I want to find is an XML validator that will read the various documents I’ve written and check them against the various schemas and DTDs referred to by the namespaces within. I don’t want an editor or a tree browser or a schema builder or anything fancy, just a tool that I can use to check a bunch of files (find . -name *.xml | xargs validate). Something like that shouldn’t be that hard to find, should it?
Maybe there’s something inside Xerces2, but the README isn’t clear (or I’m just too dense to understand it).
As soon as I’ve finished writing one, of course, there will be twenty-seven better versions out there. So maybe that’s the solution to my predicament–if you build it, they will come, in an odd way.
Looks like James Clark’s NRL (and Jing) is it. Found via Caveat Lector.
