Script may work, but it may be worth seeing how far you can get without
scripting. 

The original questions were

which I think means that you want something like the following
for the example XMl you posted?

  bash-2.01$ xt p2.xml p.xsl

  ======================
  Project p1
  Employee: 1,  Hours: 10
  Employee: 2,  Hours: 14
  Total: 24
  ======================
  
  ======================
  Project p2
  Employee: 1,  Hours: 8
  Employee: 2,  Hours: 6
  Total: 14
  ======================
  
  ======================
  Project p3
  Employee: 2,  Hours: 12
  Total: 12
  ======================
  bash-2.01$ 


If so, you may want to play with the xml code at the end of this msg.
