This interface represents an XML processing instruction (or PI) which specifies an arbitrary string of data to a named target processor. The getTarget( ) and getdata( ) methods return the target and data portions of a PI, and these values can also be obtained using the getNodeName( ) and getNodeValue( ) methods of the Node interface. You can alter the data portion of a PI with setData( ) or with the setNodeValue( ) method of Node. ProcessingInstruction nodes never have children.
