It depends on for what you need such "size".

If it's just for information, then add some counter, reset it to zero
at the <array>, increment on the every <item/> and do what you want at
the </array>.

If "size" id needed for you for pre-allocating C-style array
(something like
   item_t array[size];
or
   item_t* array = calloc(size, sizeof(item_t));
), then just use dynamically-resizable arrays.
For example, C++ std::vector if you use C++, or GArray or GPtrArray
from Glib if your language is plain C...
