You're still thinking procedurally.  "As the block chart is built, I need 
to account for arbitrary number of strings..."  Another way to say this is, 
"As the block chart is built, I need to know how many strings preceded a 
particular node."  That is, from within a template, you can do something 
like count(preceding::string).
