Public Overrides Function InsertBefore (newChild As XmlNode, refChild As XmlNode) As XmlNode
Parameters
Returns
The XmlNode inserted.
Exceptions
The current node is of a type that does not allow child nodes of the type of the newChild
node.
The newChild
is an ancestor of this node.
The newChild
was created from a different document than the one that created this node.
The refChild
is not a child of this node.
This node is read-only.
Examples
For an example of the InsertBefore method, see the InsertBefore method.
Remarks
If refChild
is null
, insert newChild
at the end of the list of child nodes. If newChild
is an XmlDocumentFragment object, its child nodes are inserted, in the same order, before refChild
. If the newChild
is already in the tree, it is first removed.
If the node being inserted was created from another document, you can use XmlDocument.ImportNode to import the node to the current document. The imported node can then be inserted into the current document.
