XmlSchemaWhiteSpaceFacet Class

Defines how the simpleType value's whitespace will be treated. Represents the World Wide Web Consortium (W3C) whiteSpace facet.

For a list of all members of this type, see XmlSchemaWhiteSpaceFacet Members.

System.Object
   System.Xml.Schema.XmlSchemaObject
      System.Xml.Schema.XmlSchemaAnnotated
         System.Xml.Schema.XmlSchemaFacet
            System.Xml.Schema.XmlSchemaWhiteSpaceFacet

[Visual Basic]
Public Class XmlSchemaWhiteSpaceFacet
   Inherits XmlSchemaFacet
[C#]
public class XmlSchemaWhiteSpaceFacet : XmlSchemaFacet
[C++]
public __gc class XmlSchemaWhiteSpaceFacet : public XmlSchemaFacet
[JScript]
public class XmlSchemaWhiteSpaceFacet extends XmlSchemaFacet

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

Remarks

The whiteSpace facet value can be one of preserve, replace, or collapse.

Example

[Visual Basic, C#, C++] The following example shows the use of the XmlSchemaWhiteSpaceFacet class.

Imports System
Imports System.Xml  
Imports System.Xml.Schema

Class XMLSchemaExamples 
    Public Shared Sub Main()

    Dim schema as New XmlSchema()

    Dim restriction as New XmlSchemaSimpleTypeRestriction()
    restriction.BaseTypeName = new XmlQualifiedName("string", "http://www.w3.org/2001/XMLSchema")

    ' <xs:whiteSpace value="collapse"/>
    Dim whiteSpace as New XmlSchemaWhiteSpaceFacet()
    whiteSpace.Value = "collapse"
