Re: [xml-dev] Noob: XML validation capabilities beyond schemas

[George Cristian Bina <george@oxygenxml.com>]

Hi John,

Schematron would be my first choice.

If you need a little more than that then you may look also into NVDL, 
this allows to validate fragments of the document with different schema 
files - these fragments can overlap and the same fragment can be 
validated with multiple schemas. From NVDL you can trigger Schematron, 
Relax NG, XML Schema validations.

If you still need more power then look into XProc. From that you can 
invoke also any type of validation but you can also do a lot of other 
processing on the XML data.

Best Regards,
George

I use the XML schema datatypes, enumeration, lists, etc. to do most of the validation I want to do.  When I need to validate something that is beyond the capabilities of RELAX NG, I have been using GNU Awk to scan the XML and do further validation, but this is messy and error-prone.
