I have two fields, say foo and bar. They both have the same format. An example of the fields could be
foo="{a=3, b=4, c=11}"
bar="{x=1, y=5, z=3}"
I want to parse and use these multivalued fields. That is, I want to be able to extract and use a, b,... and use them in calculations (using eval). Can anyone tell me whether this is even possible, and if it is, how I do it?
If you want to know all of it, what I wish to calculate is this: (a*x + b*y + c*z)/(x + y + z). In the above example, the result of this calculation would be 7.
Oh, and what makes this even more difficult (I think), is that I might actually have more fields, containing say a, b and c. So, there might as well be the field
baz="{a=23, b=1, c=6}"
I'll have to be sure I don't wind up using these values of a, b and c in the calculation.
