Overview

The XmlWhitespace class simply represents the white space within a given XML element. This class is useful for when you need to programmatically manipulate white space characters within XML documents. This class is one of the possible System.Xml.XmlCharacterData implementations.

Example (VB.NET): How to use the XMLDocument.CreateWhitespace method to create an XMLWhitespace object, and how to insert this object into an XML document.

In the sample below, we use an XMLWhitespace object to hold the carriage return/line feed character value, generated through the use of the XMLDocumentCreateWhitespace method. We then use the XMLNodeList object to hold the return value of the XMLDocument.GetElements methods. We finally navigate through this collection of elements to insert the XMLWhitespace value after the first node.

        Dim objDocument As New System.Xml.XmlDocument

        objDocument.LoadXml("<sampleElement1><sampleChild>Line 1</sampleChild><sampleChild>Line 2</sampleChild><sampleChild>Line 3</sampleChild></sampleElement1>")

        Dim objNodeList As System.Xml.XmlNodeList

        Dim objWhitespace As System.Xml.XmlWhitespace = objDocument.CreateWhitespace(CrLf)

        Dim strValues As String

        objNodeList = objDocument.GetElementsByTagName("sampleChild")

        If objNodeList.Count > 0 Then

            objNodeList(0).InsertAfter(objWhitespace, objNodeList(0).FirstChild)

        End If

        TextBox1.Text = objDocument.DocumentElement.InnerXml
