I'm not sure how to "Split it on the &, put it into a suitably keyed
structure such as a Map" other than the way I'm doing it already, unless
I'm not understanding your suggestion. So I think I need to give a bit
more info about how this is used:
I can't control the data coming in; it's from a different application
which sends this string in an encrypted form over a WAN. After I
decrypt the data string, I'm left with the string I describe below. I
need to parse out the data from the fields in the string, and then write
them out to disk in a different format. There is no other processing
done with the data, so I don't need to reference any of them more than
once. Therefore I think loading them into an array probably adds more
overhead than splitting the string the way I do right now.
Is there a more efficient "split" method I could use? Or am I
completely missing the point of what you are suggesting?

Opinion: You're optimising the wrong piece of code.
You're calling this 5 times in quick succession. This means you're
parsing the same string the same way 5 times in quick succession. Split
it on the &, put it into a suitably keyed structure such as a Map (or
even an array if you want the speed and know exactly what your
parameters are) and pass the keyed structure around. That way you only
parse the string once.
