You could, but it's probably just as easy (if not easier) to parse 
this as simple tab-separated data.

Of course, since this command is not required to generate stable 
or machine-parsable output, a better option would be to track down 
the APIs you need to call to obtain the equivalent information, 
rather than trying to parse the output of another command.
