RE: Validating JSON Data in a Host Variable

Hi Jon

Is there a similar XML valuation check?

XMLPARSE will convert a "wellformed" XML Document into an internal
representation.
If the document is not wellformed, an error occurs (SQLCODE -20398 /
SQLSTATE 2200M.

Values(XMLPARSE(Document '<root><Name>xxx</Name><Company
Name="ABC"/></root>'));

Mit freundlichen Grüßen / Best regards

Is there a similar XML valuation check? Only thing I can find is the schema
validation option - <sacrasm> and of course _all_ XML documents _always_
have schema available! </sacrasm>
