isn't that bit just
n idiv 256 + 1
rather than a repeated 'if' test?
except that I'm confused as assuming a line position assumes that your
array is a dense format with all lines present, but I suspect it isn't,
so rather than a line number don't you just want to select a line with
the appropriate base child, something like:
line[base = (n idiv 256)]
presumably things would be more efficient if you pre-processed the input
array into some more amenable format, especially as xpath can't natively
deal with integers written in hex?
