It can't.  It presumes everything are data, and quotes minimally.  You
then apply your commands on top of the prequoted sample string.

try it out. It can save you quite a bit of time going cross-eyed
proofreading.

The problem with regexes is all it takes is one char off an the whole
thing does not work.  You have no clue where the problem is.  You
rarely find errors with syntax checking. There is no trace.
The other problem is a regex will work 90% of the time.  It may be
quietly rejecting a small percentage of the strings, and you might not
notice.
