Creates a new child node at the beginning of the list of child nodes of the current node using the XML string specified.
Prepending a child node adds the new node to the beginning of the list of child nodes for the current node. For example, when three child nodes exist for an element, the prepended node becomes the first child node. If no child nodes exist, then a new child node is created.
To create a new element node, include all XML syntax in the XML string parameter. The string for a new book node is PrependChild("<book/>"). The string for appending the text "book" to the current node's text node is PrependChild("book"). If the XML string contains multiple nodes, all nodes are added.
The following are important notes to consider when using the XPathNavigator.PrependChild(string) method.
The XPathNavigator.PrependChild(string) method is valid only when the System.Xml.XPath.XPathNavigator is positioned on an element node.
The XPathNavigator.PrependChild(string) method does not affect the position of the System.Xml.XPath.XPathNavigator.
