XmlSchemaObject.Namespaces Property

Gets or sets the XmlSerializerNamespaces to use with this schema object.

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

public XmlSerializerNamespaces Namespaces { get; set; }
/** @property */
public XmlSerializerNamespaces get_Namespaces ()

/** @property */
public void set_Namespaces (XmlSerializerNamespaces value)

public function get Namespaces () : XmlSerializerNamespaces

public function set Namespaces (value : XmlSerializerNamespaces)

Property Value

The XmlSerializerNamespaces property for the schema object.

This gives the Schema Object Model (SOM) the ability to add xmlns declarations. This is useful when you want to declare a prefix to qualify declarations from an imported schema or use in the xpath attribute of the xs:selector element.

You can also use the Namespaces property to change namespace prefixes in a schema. For example, you can change the prefix used by a schema for the W3C XML Schema namespace from xs to xsd as illustrated in the following example.

XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces();
namespaces.Add("myChangedPrefix", "myImportNamespace");
s.Namespaces = namespaces;

In the following example, the prefix myImpPrefix is added at the schema element level. The prefix is then used to qualify definitions that are imported from myImportNamespace.

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

class XmlSchemaObject
{
    public static void Main()
    {
        XmlSchema s = new XmlSchema();
        s.TargetNamespace = "myNamespace";
        s.Namespaces.Add("myImpPrefix", "myImportNamespace");

        // Create the <xs:import> element.
        XmlSchemaImport import = new XmlSchemaImport();
        import.Namespace = "myImportNamespace";
        import.SchemaLocation = "http://www.example.com/myImportNamespace";
        s.Includes.Add(import);

        // Create an element and assign a type from imported schema.
        XmlSchemaElement elem = new XmlSchemaElement();
        elem.SchemaTypeName = new XmlQualifiedName("importType", "myImportNamespace");
        elem.Name = "element1";

        s.Items.Add(elem);
        s.Write(Console.Out);

    }
}

import System.*;
import System.Xml.*;
import System.Xml.Schema.*;

class XmlSchemaObject
{
    public static void main(String[] args)
    {
        XmlSchema s = new XmlSchema();
        s.set_TargetNamespace("myNamespace");
        s.get_Namespaces().Add("myImpPrefix","myImportNamespace");

        // Create the <xs:import> element.
        XmlSchemaImport importObj = new XmlSchemaImport();
        importObj.set_Namespace("myImportNamespace");
        importObj.set_SchemaLocation("http://www.example.com/myImportNamespace");
        s.get_Includes().Add(importObj);

        // Create an element and assign a type from imported schema.
        XmlSchemaElement elem = new XmlSchemaElement();
        elem.set_SchemaTypeName(new XmlQualifiedName("importType",
            "myImportNamespace"));
        elem.set_Name("element1");
        s.get_Items().Add(elem);
        s.Write(Console.get_Out());
    } //main 
} //XmlSchemaObject

The example produces the following XML.

<?xml version="1.0" encoding="IBM437"?>
<schema xmlns:myImpPrefix="myImportNamespace" targetNamespace="myNamespace" xmlns="http://www.w3.org/2001/XMLSchema">
  <import schemaLocation="http://www.microsoft.com/myImportNamespace" namespace="myImportNamespace" />
  <element name="element1" type="myImpPrefix:importType" />
</schema>
