Type: System.Xml.Schema.XmlSchemaComplexContent

System.Xml.Schema.XmlSchemaComplexContent Class

Assembly: System.Xml.dll
Namespace: System.Xml.Schema

Summary: Class that represents the complex content model for complex types. Contains extensions or restrictions on a complex type that has mixed content or elements only. Represents the World Wide Web Consortium (W3C) complexContent element.

C# Syntax:


        public class XmlSchemaComplexContent : XmlSchemaContentModel

Example

The following example creates a complexContent element.

using System;
using System.Xml;  
using System.Xml.Schema;

class XMLSchemaExamples {
    public static void Main() {
 
        XmlSchema schema = new XmlSchema();

        // <xs:complexType name="address">
        XmlSchemaComplexType address = new XmlSchemaComplexType();
        schema.Items.Add(address);
        address.Name = "address";
        
        // <xs:sequence>
        XmlSchemaSequence sequence = new XmlSchemaSequence();
        address.Particle = sequence;
        
        // <xs:element name="name"   type="xs:string"/>
        XmlSchemaElement elementName = new XmlSchemaElement();
        sequence.Items.Add(elementName);
        elementName.Name = "name";
        elementName.SchemaTypeName = new XmlQualifiedName("string", "http://www.w3.org/2001/XMLSchema");
        
        // <xs:element name="street"   type="xs:string"/>
        XmlSchemaElement elementStreet = new XmlSchemaElement();
        sequence.Items.Add(elementStreet);
        elementStreet.Name = "street";
        elementStreet.SchemaTypeName = new XmlQualifiedName("string", "http://www.w3.org/2001/XMLSchema");
        
        // <xs:element name="city"   type="xs:string"/>
        XmlSchemaElement elementCity = new XmlSchemaElement();
        sequence.Items.Add(elementCity);
        elementCity.Name = "city";
        elementCity.SchemaTypeName = new XmlQualifiedName("string", "http://www.w3.org/2001/XMLSchema");
        
        // <xs:complexType name="USAddress">
        XmlSchemaComplexType USAddress = new XmlSchemaComplexType();
        schema.Items.Add(USAddress);
        USAddress.Name = "USAddress";
        
        // <xs:complexContent>
        XmlSchemaComplexContent complexContent = new XmlSchemaComplexContent();
        USAddress.ContentModel = complexContent;
        
        // <xs:extension base="address">
        XmlSchemaComplexContentExtension extensionAddress = new XmlSchemaComplexContentExtension();
        complexContent.Content = extensionAddress;
        extensionAddress.BaseTypeName = new XmlQualifiedName("address");
        
        // <xs:sequence>
        XmlSchemaSequence sequence2 = new XmlSchemaSequence();
        extensionAddress.Particle = sequence2;
        
        // <xs:element name="state" type="xs:string"/>
        XmlSchemaElement elementUSState = new XmlSchemaElement();
        sequence2.Items.Add(elementUSState);
        elementUSState.Name = "state";
        elementUSState.SchemaTypeName = new XmlQualifiedName("string", "http://www.w3.org/2001/XMLSchema");

        
        // <xs:element name="zipcode" type="xs:positiveInteger"/>
        XmlSchemaElement elementZipcode = new XmlSchemaElement();
        sequence2.Items.Add(elementZipcode);
        elementZipcode.Name = "zipcode";
        elementZipcode.SchemaTypeName = new XmlQualifiedName("positiveInteger", "http://www.w3.org/2001/XMLSchema");
        
        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:complexType name="address">
        <xs:sequence>

            <xs:element name="street" type="xs:string"/>
            <xs:element name="city"   type="xs:string"/>
        </xs:sequence>
    </xs:complexType>
