Hi Andre,

I tested your xml and it worked fine but you are using the wrong number 
of parameters in your call to revXMLNumberOfChildren().

I get the required result (2) with both of these lines:
put revXMLNumberOfChildren(tTreeID, "methodCall/params", "param", 0)
put revXMLNumberOfChildren(tTreeID, "methodCall", "param", -1)

The first checks only for "param" in the first level of the "params" 
The second checks all levels from the root tag down and counts all 
instances of "param" in the document.

Note that although the docs indicate that the 4th parameter is 
optional, in my tests I got an error if I left it out.

BTW: if you want any more info, you might like to check out my XML 
tutorial :-)
