Elements

Nodes that represent elements are often the most common type of node to be found in a document tree structure. The DOM standard includes an Element interface that extends the Node interface to add element-specific functionality. Most of these methods are used to manage attributes, but the first three are more generalized in nature:

String   getTagName();
NodeList getElementsByTagName( String name );
void     normalize();

String   getAttribute( String name );
void     setAttribute( String name, String value )
                                  throws DOMException;
void     removeAttribute( String name )
                                  throws DOMException;

Attr     getAttributeNode( String name );
void     setAttributeNode( Attr newAttr )
                                  throws DOMException;
void     removeAttributeNode( Attr OldAttr )
                                  throws DOMException;
