The XML type, which is the abstract data type for storing XML documents, can be used when HiRDB is used together with HiRDB XML Extension.
An XML type value is an XQuery sequence. For details about XQuery sequences, see 1.15 XQuery.
Using SQL (SQL/XML) to process XML type values facilitates tasks such as filtering XML documents that match certain criteria, or retrieving the value of a particular part of the structure within an XML document.
