Description

HasChildNodes is a Boolean function which indicates if the DOM node has child nodes. In general, the return value is True when a DOM node has been assigned to the FirstChild property.

HasChildNodes always returns False in TDOMNode. TDOMNode does not allocate storage for child nodes. The method must be overridden in a descendent class which allocates storage for child nodes in the DOM node specialization.
