I see now, but I'm still thinking about alternatives that make you
not use "do". You say your script is recursively walking trough the
XML. But that would allow to only use a one dimensional array
assignment. I tried to look at your code, but it's too hard for me
to understand, oh and I also hate XML, so I made a directory walker
example instead :)
The XML code works without using do. Since it is recursive there is no
need for worrying about multi-dimensional keys. I actually chose the
recursive technique because I would have had to use 'do' in order to
use an iterative algorithm.
Basically the code returns an array, which is put into the parent
array, which is then put into the parent array, which is put into
it's parent array, etc. Would this be applicable to your XML code?
Also, I am not sure how to do the reverse, to make folders out of
the array (creating XML).
Your function is set up pretty much like the current XML converter.
The code where I currently use 'do' deals with converting SQL columns
and rows into a multi-dimensional array that mimics the parent/child
relationships of the tables in the SQL query. This is slightly more
complex then converting XML to an array since databases return flat
results and you have to manually determine the hierarchy.
I'm calling functions recursively but I am working on a reference to
the array that I am generating so there is no copying of data. Using
'do' came about because you can't pass array keys by reference. So
instead I pass a string representing the array element to act on
instead (i.e. [1][table][2]) and use that in conjunction with 'do'.
Once the engine allows variable references to be used with array keys
then out comes the 'do' and I get a speed bump.
