Bietet Unterstützung für for each-Iterationen der Knoten im XmlNode.
Namespace: System.Xml
Assembly: System.Xml (in system.xml.dll)

Hinweise
Diese Methode ist eine Microsoft-Erweiterung des Dokumentobjektmodells (Document Object Model, DOM).
Beispiel
Im folgenden Beispiel werden alle Bücher im XML-Dokument angezeigt.

public shared sub Main()
Dim doc as XmlDocument = new XmlDocument()

Console.WriteLine("Display all the books...")
Dim root as XmlNode = doc.DocumentElement
Dim ienum as IEnumerator = root.GetEnumerator()
Dim book as XmlNode
while (ienum.MoveNext())
book = CType(ienum.Current, XmlNode)
Console.WriteLine(book.OuterXml)
Console.WriteLine()
