Question

Answer 1

Without regard to implementation language, your regex might look something like this:

("[^"]*"|[^"]+)(\s+|$)

The first part "[^"]*" looks for a quoted string that doesn't contain embedded quotes, and the second part [^"]+ looks for a sequence of non-quote characters. The \s+ matches a separating sequence of spaces, and $ matches the end of the string.
