XmlSchemaAnyAttribute Class

Represents the World Wide Web Consortium (W3C) anyAttribute element.

Namespace: System.Xml.Schema
Assembly: System.Xml (in system.xml.dll)

public ref class XmlSchemaAnyAttribute : public XmlSchemaAnnotated
public class XmlSchemaAnyAttribute extends XmlSchemaAnnotated
public class XmlSchemaAnyAttribute extends XmlSchemaAnnotated
Not applicable.

The anyAttribute element enables any attribute from the specified namespace or namespaces to appear in the containing complexType element.

The following example creates the anyAttribute element.

#using <mscorlib.dll>
#using <System.Xml.dll>

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

class XmlSchemaExamples

    static void Main()
        XmlSchema^ schema = gcnew XmlSchema();

        // <element name="stringElementWithAnyAttribute">
        XmlSchemaElement^ element = gcnew XmlSchemaElement();
        element->Name = "stringElementWithAnyAttribute";

        // <complexType>
        XmlSchemaComplexType^ complexType = gcnew XmlSchemaComplexType();
        element->SchemaType = complexType;

        // <simpleContent>
        XmlSchemaSimpleContent^ simpleContent = gcnew XmlSchemaSimpleContent();
        complexType->ContentModel = simpleContent;

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

        // <anyAttribute namespace="##targetNamespace"/>
        XmlSchemaAnyAttribute^ anyAttribute = gcnew XmlSchemaAnyAttribute();
        extension->AnyAttribute = anyAttribute;
        anyAttribute->Namespace = "##targetNamespace";

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

        XmlSchema^ compiledSchema;

        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);

    static void ValidationCallbackOne(Object^ sender, ValidationEventArgs^ args)

int 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:element name="stringElementWithAnyAttribute">
                <xs:extension base="xs:string">
                    <xs:anyAttribute namespace="##targetNamespace"/>
