Net xmlvalidatingreader example
The Xml Reader is not required to perform validation but it must expand any entity references.
Saxon uses the properties of the is discouraged, because it does not expand entity references.
Let's review some XML basics before diving into how the new features in XML can help you validate XML data more easily. An XML document contains elements, attributes, and values of primitive data types.
XML data can be considered as categorically correct if it is well-formed and valid. An XSD schema defines elements, attributes, and the relationship between them.
Use the Validation Event Handler event to define an event handler for receiving the notification about XSD schema validation errors.
The Validation Event Handler callback function reports the validation errors and warnings.
Fifth, add an XSD schema to the Xml Reader Settings class through its Schemas property.
Once you complete these steps, the Xml Reader class will validate the XML document automatically while parsing the XML using the Read method.
Fourth, set Xml Reader Settings' Xsd Validate property to True.
You specify the validation settings as well as a Validation Event Handler method using the Xml Reader Settings object. I won't explain how to validate XML data using DTDs because those are not typically used outside legacy applications.
You then perform the validation during the reading and parsing operations of the factory-created Xml Reader object. Validation is the process of enforcing rules on the XML content either through an XSD schema or a DTD or XDR schema.
Being well-formed requires the XML data to be syntactically correct; otherwise, the XML parser will raise an error. It conforms to the World Wide Web Consortium (W3C) XML schema standards and recommendations. NET Framework 2.0 classes support the W3C XML schema recommendation.
XML data is valid when the elements and the content of the individual elements in the XML data conform to the declared data types specified in the schema or DTD. NET is handled primarily by the classes present in a handful of namespaces: System. The classes that are commonly employed to validate the XML document are Xml Reader, Xml Reader Settings, Xml Schema Set, and Xml Node Reader.
