Validating xml schema in net love brasil dating
Note that when validating a document the target namespace of the document must match the target namespace of the schema in the schema set. In the code example that follows, the schema above is added to the Xml Schema Set Schemas property of the Xml Reader Settings object.
The Xml Reader Settings object is passed as a parameter to the Create method of the Xml Reader object, which validates the XML document above. Schema Class Xml Schema Set Example Shared Sub Main() Dim books Settings As Xml Reader Settings = New Xml Reader Settings() books Settings.
An XML document validated against an XML Schema is both "Well Formed" and "Valid".

A Validation Event Handler is added to the Xml Reader Settings object to handle any Warning or Error events raised by errors found during the validation process of both the XML document and the schema.
Tree patterns, defined as XPath expressions, are used to make assertions, and provide user-centred reports about XML documents.
Expressing validation rules using patterns is often easier than defining the same rule using a content model.
XML documents can be validated against an XML schema definition language (XSD) schema in an Xml Schema Set.
