XmlSchemaLengthFacet Class

 

Represents the length facet from XML Schema as specified by the World Wide Web Consortium (W3C). This class can be used to specify a restriction on the length of a simpleType element on the data type.

public ref class XmlSchemaLengthFacet : XmlSchemaNumericFacet

NameDescription
System_CAPS_pubmethodXmlSchemaLengthFacet()

Initializes a new instance of the XmlSchemaLengthFacet class.

NameDescription
System_CAPS_pubpropertyAnnotation

Gets or sets the annotation property.(Inherited from XmlSchemaAnnotated.)

System_CAPS_pubpropertyId

Gets or sets the string id.(Inherited from XmlSchemaAnnotated.)

System_CAPS_pubpropertyIsFixed

Gets or sets information that indicates that this facet is fixed.(Inherited from XmlSchemaFacet.)

System_CAPS_pubpropertyLineNumber

Gets or sets the line number in the file to which the schema element refers.(Inherited from XmlSchemaObject.)

System_CAPS_pubpropertyLinePosition

Gets or sets the line position in the file to which the schema element refers.(Inherited from XmlSchemaObject.)

System_CAPS_pubpropertyNamespaces

System_CAPS_pubpropertyValue

Gets or sets the value attribute of the facet.(Inherited from XmlSchemaFacet.)

NameDescription
System_CAPS_pubmethodEquals(Object^)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

The following example shows the use of the XmlSchemaLengthFacet class.

#using <System.Xml.dll>

using namespace System;
using namespace System::Xml;
using namespace System::Xml::Schema;

ref class XMLSchemaExamples
{
private:
	static void ValidationCallbackOne(Object^ sender, ValidationEventArgs^ args)
    {
		Console::WriteLine(args->Message);
    }

public:
    static void Main()
    {
        XmlSchema^ schema = gcnew XmlSchema();

        // <xs:simpleType name="ZipCodeType">
        XmlSchemaSimpleType^ ZipCodeType = gcnew XmlSchemaSimpleType();
        ZipCodeType->Name = "ZipCodeType";

        // <xs:restriction base="xs:string">
        XmlSchemaSimpleTypeRestriction^ restriction = gcnew XmlSchemaSimpleTypeRestriction();
        restriction->BaseTypeName = gcnew XmlQualifiedName("string", "http://www.w3.org/2001/XMLSchema");

        // <xs:length value="5"/>
        XmlSchemaLengthFacet^ length = gcnew XmlSchemaLengthFacet();
        length->Value = "5";
        restriction->Facets->Add(length);

        ZipCodeType->Content = restriction;

        schema->Items->Add(ZipCodeType);

        // <xs:element name="Address">
        XmlSchemaElement^ element = gcnew XmlSchemaElement();
        element->Name = "Address";

        // <xs:complexType>
        XmlSchemaComplexType^ complexType = gcnew XmlSchemaComplexType();

        // <xs:attribute name="ZipCode" type="ZipCodeType"/>
        XmlSchemaAttribute^ ZipCodeAttribute = gcnew XmlSchemaAttribute();
        ZipCodeAttribute->Name = "ZipCode";
        ZipCodeAttribute->SchemaTypeName = gcnew XmlQualifiedName("ZipCodeType", "");
        complexType->Attributes->Add(ZipCodeAttribute);

        element->SchemaType = complexType;
        schema->Items->Add(element);

        XmlSchemaSet^ schemaSet = gcnew XmlSchemaSet();
        schemaSet->ValidationEventHandler += gcnew ValidationEventHandler(ValidationCallbackOne);
        schemaSet->Add(schema);
        schemaSet->Compile();

        XmlSchema^ compiledSchema = nullptr;

        for each (XmlSchema^ schema1 in schemaSet->Schemas())
        {
            compiledSchema = schema1;
        }

        XmlNamespaceManager^ nsmgr = gcnew XmlNamespaceManager(gcnew NameTable());
        nsmgr->AddNamespace("xs", "http://www.w3.org/2001/XMLSchema");
        compiledSchema->Write(Console::Out, nsmgr);
    }
};

int main()
{
	XMLSchemaExamples::Main();
	return 0;
}

The following XML file is generated for the preceding 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:length value="5"/>
		</xs:restriction>
	</xs:simpleType>

	<xs:element name="Address">
		<xs:complexType>
			<xs:attribute name="ZipCode" type="ZipCodeType"/>
		</xs:complexType>
	</xs:element>

</xs:schema>
