RE: Question on XSD validator

It's not so bad, considering that it's free. I've never had to look at the code. See http://xml.apache.org/xerces2-j/samples.html, particularly the DOM, SAX, and XNI samples, which explain all the command line tools and the command line options to use with them. I like xni.XMLGrammarBuilder, because in addition to validating documents against W3C schemas, it can check the schemas themselves for correctness without any document being specified, and I trust it more than XMLSpy. Like a lot of java programs, command line usage means specifying class names and command line switches, so a one-line batch file or shell script can make the name as intuitive as you want. I have one called checkSchema.bat that looks like this: java dom.ASBuilder -f -a %1 (I believe dom.AsBuilder is now deprecated in favor of xni.XMLGrammarBuilder.) I also use stdinparse from Xerces C++ (http://xml.apache.org/xerces-c/stdinparse.html) a lot.
