C++: How to ignore word in a certain position in lines being read?

My code first opens the file and gets each line from it, each line taking the form:

HEX_NUM CHAR HEX_NUM

The code I have is

stringstream s( line );
s >> std::hex >> addr >> letter >> std::hex >> target ; 

However, I would like to only get the CHAR section (without having the create the variables addr and target). How can I rewrite the 2nd line of my code to do so?
