Try doing this     Employees Employee  id 4    text

You need to remove the   before the    Predicates  the parts in      shouldn t have slashes immediately before them   Also  to select the Employee element itself  you should leave off the  text   at the end or otherwise you d just be selecting the whitespace text values immediately under the Employee element     Employee  id  4     Edit  As Jens points out in the comments     can be very slow because it searches the entire document for matching nodes  If the structure of the documents you re working with is going to be consistent  you are probably best off using a full path  for example    Employees Employee  id  4
