To add format to the XML documents you can use Extensible Stylesheet Language (XSL). It can map XML elements into other formatting or mark-up languages such as HTML.In Oracle XML DB, BEGIN -- Delete the schema, if it already exists; otherwise, this produces an error.

By default, the database checks to ensure that instances are well-formed.In addition, for schema-based XMLType instances, the database performs few basic validation checks.Because full XML schema validation (as specified by the W3C) is an expensive operation, when instances are constructed, stored, or retrieved, they are not also fully validated.To validate and manipulate the validation status of XML documents, the following functions and procedures are provided: checks if the input instance conforms to a specified XML schema.It does not change the validation status of the XML instance.If an XML schema URL is not specified and the XML document is schema-based, the conformance is checked against the own schema of the validates an XML instance against its XML schema if it has not already been done. If validation fails an error is raised otherwise, then the document status is changed to checks if the input instance conforms to a specified XML schema.

If an XML schema URL is not specified and the XML document is schema-based, then the conformance is checked against the own schema of the - Element of a specified schema, against which to validate.

This is useful when we have an XML schema which defines more than one top level element, and we want to check conformance against a specific one of these elements.

DECLARE xmldoc XMLType; BEGIN -- Populate xmldoc (for example, by fetching from table).

-- Validate against XML schema Schema Valid(' IF Schema Valid = 1 THEN -- ELSE -- END IF; END; DROP TABLE po_tab; CREATE TABLE po_tab OF XMLType XMLSCHEMA " ELEMENT "purchase Order"; CREATE TRIGGER emp_trig BEFORE INSERT OR UPDATE ON po_tab FOR EACH ROW DECLARE newxml XMLType; BEGIn newxml := :new.

XML Schema is an XML-based representation of the structure of an XML document.

Through its support for datatypes and namespaces, XML Schema has the potential to provide the standard structure for XML elements and attributes.
