How to select XMLType data in Oracle?

They provide a method for enforcing data integrity by limiting what can be placed on a field to a valid list or range of choices.
Can a CLOB be coerced into an xmltype?
Since we are not working with an explicit XMLType object (i.e. the column we are evaluating is a CLOB, not XMLType) we can use the XMLType function to coerce the CLOB into the XMLType (as long as the CLOB is valid XML, otherwise we will get error such ORA-31011: XML parsing failed and ORA-19202: Error occurred in XML processing).
How is xmltype.getclobval similar to XPath?
XMLType.getClobVal — This function returns the serialization of the current node like XPATH function ‘serialize ()’, i.e. a text in XML syntax. This function returns the serialization of the current node. This is similar to the XPATH function ‘serialize ()’, i.e. a text in XML syntax.
How to create an instance of the xmltype datatype?
