.NET Framework 3.0
Represents the minLength element from XML Schema as specified by the . This class can be used to specify a restriction on the minimum length of the data value of a simpleType element. The length must be greater than the value of the minLength element.
Namespace: System.Xml.Schema
Assembly: System.Xml (in system.xml.dll)
Assembly: System.Xml (in system.xml.dll)
The following example shows the use of the XmlSchemaMinLengthFacet class.
Imports System Imports System.Xml Imports System.Xml.Schema Class XMLSchemaExamples Public Shared Sub Main() Dim schema As New XmlSchema() ' <xs:simpleType name="ZipCodeType"> Dim ZipCodeType As New XmlSchemaSimpleType() ZipCodeType.Name = "ZipCodeType" ' <xs:restriction base="xs:string"> Dim restriction As New XmlSchemaSimpleTypeRestriction() restriction.BaseTypeName = New XmlQualifiedName("string", "http://www.w3.org/2001/XMLSchema") ' <xs:minLength value="5"/> Dim minLength As New XmlSchemaMinLengthFacet() minLength.Value = "5" restriction.Facets.Add(minLength) ZipCodeType.Content = restriction schema.Items.Add(ZipCodeType) ' <xs:element name="Address"> Dim element As New XmlSchemaElement() element.Name = "Address" ' <xs:complexType> Dim complexType As New XmlSchemaComplexType() ' <xs:attribute name="ZipCode" type="ZipCodeType"/> Dim ZipCodeAttribute As New XmlSchemaAttribute() ZipCodeAttribute.Name = "ZipCode" ZipCodeAttribute.SchemaTypeName = New XmlQualifiedName("ZipCodeType", "") complexType.Attributes.Add(ZipCodeAttribute) 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 this code example.
<?xml version="1.0" encoding="IBM437"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:simpleType name="ZipCodeType"> <xs:restriction base="xs:string"> <xs:minLength value="5"/> </xs:restriction> </xs:simpleType> <xs:element name="Address"> <xs:complexType> <xs:attribute name="ZipCode" type="ZipCodeType"/> </xs:complexType> </xs:element> </xs:schema>
