Hi Nick
QCStructures that you can pass from path to patch in QC can either contain
complex objects with the {key: value, key: value,…} representation or more
straight forward arrays which have the [value, value, …] representation. With
the object model you need the right key to get the corresponding value. With
arrays you need the index number, typically starting at zero. In some languages
all Array elements are by definition of the same type, e.g. numbers or strings
or booleans only but not so in QC. Anyhow elements are referenced by their
place in the array, i.e. by there index number (which is shown in QC hints as
n: (n) = … where n is the index number)
Anyhow the song example you choose wasn’t ideal as you have too fields saying
AC/DC (ac/dc, ac_dc). It will be either of those and just use the index number
in the brackets , either 1 or 3 in this case.

Also if you want to use the iTunes XML file you can parse it in TextWranggler
(free app) or any decent coding editor to remove a bunch of the info you don’t
need. You will need to learn a tiny bit of GREP but Text Wrangler has an
excellent introduction and tuition in the manual for GREP. you can replace all
the extraneous info with nothing and get the file size down if it’s overloaded
with things you don’t need (especially if artwork is encoded into the XML that
will take up a lot of memory).
