XmlSchemaFractionDigitsFacet Class
Specifies a restriction on the number of digits that can be entered for the fraction value of a simpleType element. The value of fractionDigits must be a positive integer. Represents the World Wide Web Consortium (W3C) fractionDigits facet.
Assembly: System.Xml (in System.Xml.dll)
The following example shows the use of the XmlSchemaFractionDigitsFacet class.
Imports System Imports System.Xml Imports System.Xml.Schema Class XMLSchemaExamples Public Shared Sub Main() Dim schema As New XmlSchema() '<xs:simpleType name="RatingType"> Dim RatingType As New XmlSchemaSimpleType() RatingType.Name = "RatingType" '<xs:restriction base="xs:number"> Dim restriction As New XmlSchemaSimpleTypeRestriction() restriction.BaseTypeName = New XmlQualifiedName("decimal", "http://www.w3.org/2001/XMLSchema") '<xs:totalDigits value="2"/> Dim totalDigits As New XmlSchemaTotalDigitsFacet() totalDigits.Value = "2" restriction.Facets.Add(totalDigits) '<xs:fractionDigits value="1"/> Dim fractionDigits As New XmlSchemaFractionDigitsFacet() fractionDigits.Value = "1" restriction.Facets.Add(fractionDigits) RatingType.Content = restriction schema.Items.Add(RatingType) '<xs:element name="movie"> Dim element As New XmlSchemaElement() element.Name = "movie" '<xs:complexType> Dim complexType As New XmlSchemaComplexType() '<xs:attribute name="rating" type="RatingType"/> Dim ratingAttribute As New XmlSchemaAttribute() ratingAttribute.Name = "rating" ratingAttribute.SchemaTypeName = New XmlQualifiedName("RatingType", "") complexType.Attributes.Add(ratingAttribute) element.SchemaType = complexType schema.Items.Add(element) 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 nsmgr As New XmlNamespaceManager(New NameTable()) nsmgr.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema") compiledSchema.Write(Console.Out, nsmgr) End Sub Public Shared Sub ValidationCallbackOne(ByVal sender As Object, ByVal args As ValidationEventArgs) Console.WriteLine(args.Message) End Sub End Class
The following XML file is generated for the preceding code example.
