Contains the parent node.

Script Syntax

var objXMLDOMNode = oXMLDOMNode.parentNode;

Example

The following script example sets a variable ('newNode') to reference the parent node of another IXMLDOMNode object ('currNode'). It then uses the reference to the new node to display the XML contents of its parent node.

var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.3.0");
var currNode;
var newNode;
xmlDoc.async = false;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode != 0) {
   var myErr = xmlDoc.parseError;
   WScript.Echo("You have error " + myErr.reason);
} else {
   currNode =    xmlDoc.documentElement.childNodes.item(1).childNodes.item(0);
   newNode = currNode.parentNode;
   WScript.Echo(newNode.xml);
}

Visual Basic Syntax

Set objXMLDOMNode = oXMLDOMNode.parentNode

C/C++ Syntax

HRESULT get_parentNode(  
    IXMLDOMNode **parent);

Parameters

parent[out, retval]
The parent of the given node instance.

C/C++ Return Values

S_FALSE
The value returned if there is no parent.

S_OK
The value returned if successful.

E_INVALIDARG
The value returned if the parent parameter is Null.

Remarks

The property is read-only. All nodes except Document, DocumentFragment, and Attribute nodes can have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, the parent is Null.

This value depends on the value of the nodeType property.

NODE_ATTRIBUTE NODE_DOCUMENT NODE_DOCUMENT_FRAGMENT	Returns Null; these nodes do not have parents.
NODE_CDATA_SECTION	Returns the element or entity reference containing the CDATA section.
NODE_COMMENT	Returns the element, entity reference, document type, or document containing the comment.
NODE_DOCUMENT_TYPE	Returns the document node.
NODE_ELEMENT	Returns the parent node of the element. If the element is the root node in the tree, the parent is the document node. If the node is the document node, `parentNode` is Null.
NODE_ENTITY	Returns the document type node.
NODE_ENTITY_REFERENCE	Returns the element, attribute, or entity reference containing the entity reference.
NODE_NOTATION	Returns the document type node.
NODE_PROCESSING_INSTRUCTION	Returns the document, element, document type, or entity reference containing the processing instruction.
NODE_TEXT	Returns the parent element, attribute, or entity reference.
