How to extract shared library version from SONAME field?

Question

There is a shared library say, libsample.so & libsample.so.abc.xy (a,b,c,x and y are 0-9), former having soft link to latter.

How to extract "abc.xy" field from SONAME section of libsample.so?

I have tried below command : $ objdump -p libsample.so | grep SONAME | awk {' print $2'} this prints : libsample.so.abc.xy

But how to further fetch "abc.xy"?
