Examples of org.w3c.dom.Document.importNode()

org.w3c.dom.Document.importNode()
Imports a node from another document to this document. The returned node has no parent; (parentNode is null ). The source node is not altered or removed from the original document; this method creates a new copy of the source node.
For all nodes, importing a node creates a node object owned by the importing document, with attribute values identical to the source node's nodeName and nodeType , plus the attributes related to namespaces (prefix , localName , and namespaceURI ). As in the cloneNode operation on a Node , the source node is not altered.
Additional information is copied as appropriate to the nodeType , attempting to mirror the behavior expected if a fragment of XML or HTML source was copied from one document to another, recognizing that the two documents may have different DTDs in the XML case. The following list describes the specifics for every type of node.

ELEMENT_NODE

Specified attribute nodes of the source element are imported, and the generated Attr nodes are attached to the generated Element . Default attributes are not copied, though if the document being imported into defines default attributes for this element name, those are assigned. If the importNode deep parameter was set to true , the descendants of the source element will be recursively imported and the resulting nodes reassembled to form the corresponding subtree.

ATTRIBUTE_NODE

The specified flag is set to true on the generated Attr . The descendants of the source Attr are recursively imported and the resulting nodes reassembled to form the corresponding subtree. Note that the deep parameter does not apply to Attr nodes; they always carry their children with them when imported.

TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE

These three types of nodes inheriting from CharacterData copy their data and length attributes from those of the source node.

ENTITY_REFERENCE_NODE

Only the EntityReference itself is copied, even if a deep import is requested, since the source and destination documents might have defined the entity differently. If the document being imported into provides a definition for this entity name, its value is assigned.

ENTITY_NODE

Entity nodes can be imported, however in the current release of the DOM the DocumentType is readonly. Ability to add these imported nodes to a DocumentType will be considered for addition to a future release of the DOM. On import, the publicId , systemId , and notationName attributes are copied. If a deep import is requested, the descendants of the the source Entity is recursively imported and the resulting nodes reassembled to form the corresponding subtree.

PROCESSING_INSTRUCTION_NODE

The imported node copies its target and data values from those of the source node.

DOCUMENT_NODE

Document nodes cannot be imported.

DOCUMENT_TYPE_NODE

DocumentType nodes cannot be imported.

DOCUMENT_FRAGMENT_NODE

If the deep option was set true , the descendants of the source element will be recursively imported and the resulting nodes reassembled to form the corresponding subtree. Otherwise, this simply generates an empty DocumentFragment .

NOTATION_NODE

Notation nodes can be imported, however in the current release of the DOM the DocumentType is readonly. Ability to add these imported nodes to a DocumentType will be considered for addition to a future release of the DOM. On import, the publicId and systemId attributes are copied. Note that the deep parameter does not apply to Notation nodes since they never have any children.

@param importedNode The node to import. @param deep If true , recursively import the subtree under the specified node; if false , import only the node itself, as explained above. This does not apply to Attr , EntityReference , and Notation nodes. @return The imported node that belongs to this Document . @exception DOMException NOT_SUPPORTED_ERR: Raised if the type of node being imported is not supported. @since DOM Level 2
