XmlSchemaAnyAttribute Class

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

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

public class XmlSchemaAnyAttribute : 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 System;
using System.Xml;
using System.Xml.Schema;

class XMLSchemaExamples
{
    public static void Main()
    {

        XmlSchema schema = new XmlSchema();

        // <element name="stringElementWithAnyAttribute">
        XmlSchemaElement element = new XmlSchemaElement();
        schema.Items.Add(element);
        element.Name = "stringElementWithAnyAttribute";

        // <complexType>
        XmlSchemaComplexType complexType = new XmlSchemaComplexType();
        element.SchemaType = complexType;

        // <simpleContent>
        XmlSchemaSimpleContent simpleContent = new XmlSchemaSimpleContent();
        complexType.ContentModel = simpleContent;

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

        // <anyAttribute namespace="##targetNamespace"/>
        XmlSchemaAnyAttribute anyAttribute = new XmlSchemaAnyAttribute();
        extension.AnyAttribute = anyAttribute;
        anyAttribute.Namespace = "##targetNamespace";

        XmlSchemaSet schemaSet = new XmlSchemaSet();
        schemaSet.ValidationEventHandler += new ValidationEventHandler(ValidationCallbackOne);
        schemaSet.Add(schema);
        schemaSet.Compile();

        XmlSchema compiledSchema = null;

        foreach (XmlSchema schema1 in schemaSet.Schemas())
        {
            compiledSchema = schema1;
        }

        XmlNamespaceManager nsmgr = new XmlNamespaceManager(new NameTable());
        nsmgr.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema");
        compiledSchema.Write(Console.Out, nsmgr);
    }
    public static void ValidationCallbackOne(object sender, ValidationEventArgs args)
    {

        Console.WriteLine(args.Message);
    }
}

The following XML file is generated for the preceding code example.


<?xml version="1.0" encoding="IBM437"?>

    <xs:element name="stringElementWithAnyAttribute">
