Code:
awk -F'"' '/x1/{a+=$(NF-1)}/x2/{b+=$(NF-1)}END{print "x1-> " a, " x2-> " b}' file

x1-> 497.3  x2-> 202.12

or with a new line in between

Code:
awk -F'"' '/x1/{a+=$(NF-1)}/x2/{b+=$(NF-1)}END{print "x1-> " a, "\nx2-> " b}' file

x1-> 497.3
x2-> 202.12

If the file has more than three fields, use ...

Code:
awk -F'","' '/x1/{a+=$3+0}/x2/{b+=$3+0}END{print "x1-> " a, "\nx2-> " b}' file

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk
