Имея серьезные проблемы с xpath против мыла, пожалуйста

У меня большие трудности с получением значения определенных узлов в этом мыльном сообщении. Пожалуйста помоги.

Мне нужно получить узел SubTotal (значение = 68682):

"/child::soap:Envelope/child::soap:Body/child::def:ValuationOut/child::def:MMHValuation/child::def:CalculationResult/child::def:PrimaryStructureStandardizedCost/child:: def:Промежуточный итог"

По какой-то причине приведенное выше выражение xpath не работает. Пожалуйста помоги.
