Following are the steps to using Xml Reader Settings for validating an XML file: The code behaves the same in both the cases.
However, there is a small difference in how the exception message is displayed.
It also provides an event (Validation Event Handler) which is fired as soon as an exception occurs in validating the XMLDocument.
I have created some xml and used the visual studio to generate the schema. The problem I am having is that the validation event fires for each node in the xml. Compile(Address Of Validation Event Handler) col Schemas. Validation Event Handler, Address Of Validation Event Handler 'Add schema to the validating reader xml Validator. Read( Validator Reader, Address Of veh) Xml Schema:: Read( ) returns an Xml Schema. Read( _ Validator Reader, _ Address Of Validation Event Handler _ ) ' Validation Schema is no longer empty.
It seems to be completely ignoring the schema that I have used. Thanks Andy public sub Main() Dim s Schema As String = " target Namespace=' xmlns:mstns=' xmlns=' xmlns:xs=' xmlns:msdata='urn:schemas-microsoft-com:xml-msdata' attribute Form Default='qualified' element Form Default='qualified'" Dim Validator Reader As New Xml. Add(Validation Schema) 'XML to validate Dim s XML As String = "" Dim Input XMLReader As New Xml. There is no variable on the left-hand side to receive that Xml Schema that it's read, so it just gets thrown away.
Well, let's look carefully at how Validation Schema is being created. Add(Validation Schema) On the first line, Validation Schema is created as an empty schema.
I'm wondering if I need to do something extra to tell the xml which schema to use. Compile(Address Of Validation Event Handler) col Schemas.
