System.Xml.Schema.XmlSchemaAnyAttribute Class

Assembly: System.Xml.dll
Namespace: System.Xml.Schema
Summary
Enables any attribute from the specified namespace or namespaces to appear in the containing complexType element. Represents the World Wide Web Consortium (W3C) anyAttribute element.
C# Syntax:
public class XmlSchemaAnyAttribute : XmlSchemaAnnotated
Example
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";
 
        schema.Compile(new ValidationEventHandler(ValidationCallbackOne));
 	XmlNamespaceManager nsmgr = new XmlNamespaceManager(new NameTable());
        nsmgr.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema");
        schema.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:schema  xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="stringElementWithAnyAttribute">
        <xs:complexType>
            <xs:simpleContent>
                <xs:extension base="xs:string">
                    <xs:anyAttribute namespace="##targetNamespace"/>
                </xs:extension>
            </xs:simpleContent>
        </xs:complexType>
    </xs:element>
</xs:schema>
