cmp 2 variables

Hi I have two variables contining a set of near identical lines, i'd like to list the lines that differ? Prefereably i'd like not to save the variables into a file first.

i.e
var1
tag:val1
tag:val2
tag:val3

var2
tag:val1
tag:val4
tag:val3

i'd like the result to print out something like tag:val2 <> tag:val4.

I was thinking of using cmp to get the line numbers and then sed/awk to get the output.

I ideas on the 'best' solution to this?

thanks in advance.
