Hi friends,
i am also facing some problem with schema validation, i have followed
all the steps
at http://developer.marklogic.com/howto/tutorials/2007-04-schema.xqy .
I tested it and it is working fine as per tutorial.
But i removed some of the required elements from xml and i did
schema validation on the new xml.
the validate function did not throw any exceptions. as per schema the
xml file is wrong, but i failed to get exception by using marklogic
function.
how to use validate lax {$node} , i want to chk a xml file with schema
before inserting .
Please help me out. What I need to do so that when I load a new xml file
into the database then MarkLogic should validate it before loading
and also
will it possible to check on collection level, with out providing
schema location in xml file.
Thanks and Regards,
Ashwini.
