Your regular expression has more than three capturing groups and
capturing groups inside other capturing groups are NOT ignored.  So
you're using incorrect references to groups.

It might be much simpler to tokenize your input on white space and test
the first two results for "is this a section num?" and "is this a
section name?" before putting everything after the first two back
together.
