Thanks, that makes sense but it's not 100% valid for me as I've more kind of 
valid "speps":

step1     = node_name
step2     = node_name L_BRACKET position R_BRACKET
step3     = node_name L_BRACKET attr R_BRACKET L_BRACKET position R_BRACKET
step      = step1 | step2 | step3

The separator after any step could be "/" or eof, so it wouldn't be very 
ellegant if I must inspect the remaining char (or chars as L_BRACKET) to 
decide where "node_name" ends.

However I already resolved it by adding a "sempaphore".

Thanks a lot.
