XML in a Nutshell, 3rd Edition

Name

ownerDocument: Document

Synopsis

Returns a reference to the Document used to create this Node object. Since the Document object is the only mechanism exposed for creating new nodes, even these newly created, empty nodes have the ownerDocument property set. This attribute can be null only for Document nodes and DocumentType nodes that are not yet part of a document. You can’t move a node directly to another document; instead, you must import it. This property can be useful for checking where a node came from.

Java binding

public Document getOwnerDocument( );

Java example

// Add my two cents
Document doc = elem.getOwnerDocument( );
Text txtAdd = doc.createTextNode("My $.02");
elem.appendChild(txtAdd);
