OK, I gotcha. So the "position" in the xml-tags block remains the same after 
the function moves the position to the tail UNLESS the xml-tags block is 
named again within the function. Therefore, it is better to name the xml-tags 
block within the function.

Unless I do this...

In order to be able to write another function within the object which can use 
the same xml-tags block instead of naming its own, I need to make each 
function return xml-tags to the head of the block at the end of the for loop. 
THEN I can have xml-tags outside the functions and useable by any functions 
within the object.

(the above understanding was written by a non-programmer. can you tell?)
