This seems to give the answers you want

/^\s+\d+\s+(.*?)\s+\d+\s+(.*?)$/;

It's worth looking at the $`, $& and $' variables to help you debug regular expressions.

    If he want match also leading space (" 4.393864E+00 .0" instead of "4.393864E+00 .0") I suggest

    /^\s+\d+\s(.*?)\s+\d+\s(.*?)$/

    It's relavant to note that the speed of the regexp code in Perl decreases when these variables are used.

      Absolutely. Use them for debugging, but don't use them in production code - unless you really need to :)
