The XPathNodeType of the descendant nodes.
- matchSelf
- Boolean
true to include the context node in the selection; otherwise, false.
Returns
An XPathNodeIterator that contains the selected nodes.

Selects all the descendant nodes of the current node with the local name and namespace URI specified.
public:

override this.SelectDescendants : string * string * bool -> System.Xml.XPath.XPathNodeIteratorPublic Overridable Function SelectDescendants (name As String, namespaceURI As String, matchSelf As Boolean) As XPathNodeIteratorParameters
- name
- String
The local name of the descendant nodes.
- namespaceURI
- String
The namespace URI of the descendant nodes.
- matchSelf
- Boolean
true to include the context node in the selection; otherwise, false.
Returns
An XPathNodeIterator that contains the selected nodes.
Exceptions
null cannot be passed as a parameter.
Examples
For an example of selecting ancestor, child, and descendant nodes, see SelectAncestors.
Remarks
If String.Empty is specified as the name parameter, all descendant nodes that belong to the specified namespace URI are selected. If String.Empty is specified as the namespaceURI parameter, all descendant nodes with the specified local name that belong to no namespace are selected. If both the local name and namespace URI parameters are String.Empty, all descendant nodes that belong to no namespace are selected.
A descendant is a child or a child of a child and so on; thus the selected nodes will never contain attribute or namespace nodes.
The SelectDescendants method has no effect on the state of the XPathNavigator.
