Each node has a parent that is specified by the Node.ParentNode property. A node does not have a parent node (ParentNode is null) when a node has just been created and not yet added to the tree, or if it has been removed from the tree. You can remove a node from its parent by calling Node.Remove.

The parent node of the root Document node is always null.

Example AccessParentNode

Shows how to access the parent node.

[C#]

 

// Create a new empty document. It has one section.

Document doc = new Document();

 

// The section is the first child node of the document.

Node section = doc.FirstChild;

 

// The section's parent node is the document.

Assert.AreEqual(doc, section.ParentNode);

 

 

[Visual Basic]

 

' Create a new empty document. It has one section.

Dim doc As Document = New Document()

 

' The section is the first child node of the document.

Dim section As Node = doc.FirstChild

 

' The section's parent node is the document.

Assert.AreEqual(doc, section.ParentNode)

 

 

[Java]

 

// Create a new empty document. It has one section.

Document doc = new Document();

 

// The section is the first child node of the document.

Node section = doc.getFirstChild();

 

// The section's parent node is the document.

Assert.assertEquals(doc, section.getParentNode());
