An iterator is created for all nodes of a parsed XML and used to iterate. To identify nodes that are not elements, down casts are performed from IF_IXML_NODE to IF_IXML_ELEMENT . Both the usual down casts with the casting operator CAST and a TRY control structure are demonstrated and down casts using the method QUERY_INTERFACE of the interface
IF_IXML_UNKNOWN .
