Hi,
I'm going to start work on another XML todo item:
"Add XML Schema validation and xmlvalidate function (SQL:2008)"
The standard identifies XMLVALIDATE as:
<XML validate> ::=
XMLVALIDATE <left paren>
<document or content or sequence>
<XML value expression>
[ <XML valid according to clause>]
<right paren>
so I've got something quite clear to work too. libxml has the required
support for schema validation so I'll just be wrapping it's
functionality much like I did for xpath_exists().
Anyone got any thoughts before I get busy?
Thanks,
