I am using MarkLogic 8.0-8 version.
Is it possible to validate an XML using schematron?
Please help me with an example.
Yes, as of MarkLogic 9.0.7, there is built-in support for Schematron.
http://docs.marklogic.com/schematron
To use the schematron XQuery library module as part of your own XQuery module, include the following lines in your XQuery prolog:
import module namespace schematron = "http://marklogic.com/xdmp/schematron"
at "/MarkLogic/schematron/schematron.xqy";
For more information and usage examples, see the Validating Schemas Using Schematron section in the Application Developers Guide.
