The Validate(xmlDoc) command validates an XML element xmlDoc (typically the root element of an XML document). If xmlDoc is determined to be valid according to the specified DTD/schema, then Validate returns true. Otherwise, Validate returns an error containing a description of problems found in the document.

The opts argument must be one of the following.

dtd=location

Specifies the location of the DTD to be used.

schema=location

Specifies the target no namespace XML Schema Location. If present, xmlDoc's own noNamespaceSchemaLocation attribute is effectively ignored.

Note: If neither the dtd option nor the schema option is present, then xmlDoc is checked for well-formedness only.
