Short answer - It depends (doesn't it always :) )
Long answer,
If I assume there is no relationship between the 5th occurence of
"something" (A) and the 9th occurrence of "whatever" (B)
then the answer is no - you probably cannot do it in one rule. The reason
being is that you want parse to essentially go back and process the input a
second time in order to find B. So, need to call parse once to find (A),
again to find (B) and then just do a copy/part A B.
If however, there is a relationship, like all 9 occurrences of "whatever"
always follow A then yes you can probably do it in a single parse rule. So
what you need to do to use parse is to identify the rules that the page
structure follows - or at least a pattern that you can exploit.
If you have a concrete example, it might help.
Brett.
