Meanwhile i solved the inconsistency. Further investigation yields for the xpath expression //table[1]/tr/td[2]/a/div/h3[\@class='sect2']. The reason of the error was that i relied to heavily on the output of 'XPath Helper' (a chrome extension). Is there any linux based browser which could help to extract a xpath of an website element correctly?
