In this example, the validation errors were introduced after the XML document was loaded and were found using the Validate method of the Xml Document class.
As the XML document was loaded, any schema validation errors encountered would have been handled by the validation event handler method and written to the console.
It also specifies that the elements and data types that come from the " namespace should be prefixed with xs: This fragment: specifies the default namespace declaration.
This declaration tells the schema-validator that all the elements used in this XML document are declared in the "https:// namespace.
The first way to validate an XML document is to validate the document as it is loaded into an Xml Document object using a validating Xml Reader object. Create("contoso Books.xml", settings) Dim document As Xml Document = New Xml Document() document. The result is a previously untyped XML document in the Xml Document object replaced with a typed document. Load("contoso Books.xml") Dim navigator As XPath Navigator = document. Validate(validation) End Sub Shared Sub Schema Validation Handler(By Val sender As Object, By Val e As Validation Event Args) Select Case e. A plugin called xml tools is also free to download.One feature of the plugin is the ability to validate XML against an XSD. In the case of validation, you can create an XPath Document object just like you create an Xml Document object using a validating Xml Reader object as described earlier in this topic. Because the XPath Document class is a read-only class, XPath Navigator object's returned from XPath Document objects cannot edit the XML document contained in the XPath Document object.
