Python Selenium - NamespaceError incorrect namespaces

Ahoj,

používám Python + Selenium a jako indentifikaci HTML elementů Xpath. Moje definice jednoho elemenetu je:

positiveORVXPosition = "id('major_select__View_3')/x:div/x:div/x:div/x:div/x:table/x:tbody/x:tr/x:td"

Firefox s doplňkem Xpath checker tuto definici v pohodě uznává, avšak když pak spustím skript, tak dostanu tuto chybu NamespaceError: An attempt was made to create or change an object in a way which is incorrect with regard to namespaces, avšak já v Xpath žádný mezery nevidím, co s tím? děkuji předem
