XmlAttribute.InsertBefore Method

Inserts the specified node immediately before the specified reference node.

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)

public override XmlNode InsertBefore(
	XmlNode newChild,
	XmlNode refChild
)

Parameters

newChild
Type: System.Xml.XmlNode

The XmlNode to insert.

refChild
Type: System.Xml.XmlNode

The XmlNode that is the reference node. The newChild is placed before this node.

Return Value

Type: System.Xml.XmlNode
The XmlNode inserted.

ExceptionCondition
InvalidOperationException

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.

ArgumentException

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.

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.

For an example of the InsertBefore method, see the InsertBefore method.
