How to use boost split to split a string and ignore empty values?

Question

I am using boost::split to parse a data file. The data file contains lines such as the following.

data.txt

1:1~15  ASTKGPSVFPLAPSS SVFPLAPSS   -12.6   98         


        

Answer 1

Leading and trailing whitespace is intentionally left alone by boost::split because it does not know if it is significant or not. The solution is to use boost::trim before calling boost::split.

#include 

....

boost::trim(buf);
