XmlElement.AppendChildren (gb.xml)
Sub AppendChildren ( NewChildren As XmlNode[] )
Adds all the nodes contained in the 
NewChildren array to the end of the list of children of this element.
  This method is a faster way to do :
Dim tNode As XmlNode
Dim element As New XmlElement("foo")
For Each tNode in NewChildren
  element.AppendChild(tNode)
