Synopsis
XMLType.createSchemaBasedXML
(
|
in
schema_url
varchar
); |
Description
The function creates a new instance of XMLType by copying the given one and assigning a new schema URL to it.
Parameter schema_url
specifies a new URL; if it is omitted then a non-schema based instance is created like
the XMLType.createNonSchemaBasedXML()
function.
The returned copy has an internal "validated" flag set to 0, even if the new URL is equal to the URL of the original instance.
Parameters
schema_url
The location of a schema of a new instance.
Return Types
The member function returns a new instance of XMLType.

result_names (PROBE);
orig_instance := XMLType ('<sample-xml/>');
result (concat (
'"orig_instance" is declared as non schema-based, URI=',
cast (orig_instance.getSchemaURL() as varchar) ) );
schema_based_copy := orig_instance.createSchemaBasedXML (
'http://www.example.com/test.xsd' );
result (concat (
