Imports System Imports System.Xml Imports System.Xml.Schema _ Class XMLSchemaExamples Public Shared Sub Main() Dim xtr As New XmlTextReader("example.xsd") Dim schema As XmlSchema = XmlSchema.Read(xtr, New ValidationEventHandler(AddressOf ValidationCallbackOne)) Dim schemaSet As New XmlSchemaSet() AddHandler schemaSet.ValidationEventHandler, AddressOf ValidationCallbackOne schemaSet.Add(schema) schemaSet.Compile() Dim compiledSchema As XmlSchema = Nothing For Each schema1 As XmlSchema In schemaSet.Schemas() compiledSchema = schema1 Next Dim schemaObject As XmlSchemaObject For Each schemaObject In compiledSchema.Items If schemaObject.GetType() Is GetType(XmlSchemaSimpleType) Then Dim simpleType As XmlSchemaSimpleType = CType(schemaObject, XmlSchemaSimpleType) Console.WriteLine("{0} {1}", simpleType.Name, simpleType.Datatype.ValueType) End If If schemaObject.GetType() Is GetType(XmlSchemaComplexType) Then Dim complexType As XmlSchemaComplexType = CType(schemaObject, XmlSchemaComplexType) Console.WriteLine("{0} {1}", complexType.Name, complexType.Datatype.ValueType) End If Next schemaObject xtr.Close() End Sub 'Main Public Shared Sub ValidationCallbackOne(ByVal sender As Object, ByVal args As ValidationEventArgs) Console.WriteLine(args.Message) End Sub 'ValidationCallbackOne End Class 'XMLSchemaExamples
