Help keep track of iteration total

&windowNum0=1&style0=picture&frame0=zbar&&width0=34&&height0=34&loe0=1&temp0=0&argon0=0&obscure0=0&grids0=&&product00=CDI Royal&price00=191&&product01=CDI Comfort&price01=167&&product02=EPI 5200&price02=150&&product03=EPI 6200&price03=162&TotalProducts0=4&&windowNum1=1&style1=picture&frame1=block&&width1=33&&height1=33&loe1=1&temp1=0&argon1=0&obscure1=0&grids1=&&product10=CDI Royal&price10=191&&product11=CDI Comfort&price11=167&&product12=EPI 5200&price12=150&&product13=EPI 6200&price13=162&TotalProducts1=4&TotalWindows=2&

given the above set of data, how would i parse this to get seperate totals for each brand.
cdi comfort =
cdi royal=
…and so on.

im looking for a strategic answer perhaps?
any help is appreciated…
