Single Column Parser

Looking for TSQL stored procedure code to parse a single column's value into pieces (each piece stored in a seperate variable) for a subsequent update of other columns on this row -- (generically):

1. Declare/Open cursor on TBLx where COOKIES like '%CLIENT1=' or like '%CLIENT2=%' or like '%CLIENT3=%'
2. Fetch row; initiate 3 Loops to locate the trailing values of CLIENT1=nn, CLIENT2=nn,CLIENT3=nn (eg. CLIENT1=3243, CLIENT2=11, CLIENT3=4451)
3. Save the 3 values in variables (eg @VARclient1=3245, @VARclient2=11, @VARclient3=4451)
4. UPDATE where current of cursor.. SET COL1=@VARclient1, COL2=@VARclient2, col3=@VARclient3)

Caveat.. in step 2 above, the various CLIENT strings can be listed in various orders in any various start positions w/in the COOKIEs column)
(eg. CLIENT3=732,CLIENT1=9,CLIENT2=32 ----- starting in a variable position)

I'm familiar w/ the CHARINDEX feature... Any smaple code would be greatly appreciated.. thx in advance!
