I do not think that regex will work if you have trailling whitespace in your input data (which there appears to be in your example above). To deal with that, try something like

m/(\w+)\W*$/;

instead and see how you get on.

    Might just be style but I'd make the trailing whitespace removal a bit more specific ("\W" to "\s"):

    m/(\w+)\s*$/;
