[SR-Users] xmlops/xpath access of multiple nodes

[Daniel-Constantin Mierla]

Hello,

full xpath syntax should be exported, iirc, there is an xpath function 
named position() that can be used to build expression to select the 
desired note. perhaps googling this xpath function will reveal some 
examples/hints.

Cheers,
Daniel
