System.Xml.Schema.XmlSchemaSimpleContent Class

Assembly: System.Xml.dll
Namespace: System.Xml.Schema
Summary
Class for simple types and complex types with a simple content model. Represents the World Wide Web Consortium (W3C) simpleContent element.
C# Syntax:
public class XmlSchemaSimpleContent : XmlSchemaContentModel
Remarks
XmlSchemaSimpleContent is used to indicate that the content model of the new type contains only character data and no elements. It does this through XmlSchemaSimpleContentExtension or XmlSchemaSimpleContentRestriction.
Example
The following example shows the XmlSchemaSimpleContent class.
using System;
using System.Xml;  
using System.Xml.Schema;

class XMLSchemaExamples {
    public static void Main() {
 
        XmlSchema schema = new XmlSchema();
   
        // <xs:element name="generalPrice">
        XmlSchemaElement generalPrice = new XmlSchemaElement();
        generalPrice.Name = "generalPrice";

        // <xs:complexType>
        XmlSchemaComplexType ct = new XmlSchemaComplexType();

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

        // <xs:attribute name="currency" type="xs:string" />
        XmlSchemaAttribute currency = new XmlSchemaAttribute();
        currency.Name = "currency";
        currency.SchemaTypeName = new XmlQualifiedName("string", "http://www.w3.org/2001/XMLSchema");
        simpleContent_extension.Attributes.Add(currency);

        simpleContent.Content = simpleContent_extension;
        ct.ContentModel = simpleContent;
        generalPrice.SchemaType = ct;

        schema.Items.Add(generalPrice);
           
        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="generalPrice">
      <xs:complexType>

          <xs:extension base="xs:decimal">
            <xs:attribute name="currency" type="xs:string" />
          </xs:extension>

ctor #1
Summary:
Default constructor. This constructor is called by derived class constructors to initialize state in this type.
C# Syntax:
public XmlSchemaSimpleContent();

Return to top


Property: Annotation (read-write)
Inherited
See base class member description: System.Xml.Schema.XmlSchemaAnnotated.Annotation

Summary
Gets or sets the annotation property.
C# Syntax:
public XmlSchemaAnnotation Annotation {get; set;}

Return to top


Overridden Property: Content (read-write)
Summary
Gets one of the XmlSchemaSimpleContentRestriction or XmlSchemaSimpleContentExtension.
C# Syntax:
public override XmlSchemaContent Content {get; set;}
Remarks
The simpleContent element enables you to specify an element as containing a simple type with no elements and restrict the value of the element's content or extend the content with attributes.
Example
Using the simpleContent element, the following element declaration contains a complexType that defines the content of the element as a decimal type with a single attribute (sizing):
              <xs:element name="shoeSize">
                <xs:complexType>
                  <xs:simpleContent>
                    <xs:extension base="xs:decimal">
                      <xs:attribute name="sizing">
                        <xs:restriction base="xs:string">
                          <xs:enumeration value="US"/>
                          <xs:enumeration value="European"/>
                          <xs:enumeration value="UK"/>
