currently:
both the XQUF query and test query shall use employee[2] as the input 
works-mod.xml (see below), only the second employee has both element and text nodes

<?xml version="1.0"?>
 <works>
  <employee name="Jane Doe 1" gender="female">
   <empnum>E1</empnum>
   <pnum>P1</pnum>
   <hours>40</hours>
  </employee>
  <employee name = "John Doe 2" gender="male">
   <empnum>E1</empnum>
   <pnum>P2</pnum>
   <hours>70</hours>
   <hours>20</hours>Text data from Employee[2]
  </employee>
