i'm starting with a string such as "Na**3C**6H**5O**7*2H**20"
im attempting to match all **\d+ ...once i can match all the double
asterix \d i intend to wrap the \d in "<sub>" tags for display
purposes.
i have been trying to write the correct pattern for 2 weeks now without
any success...i can get preg_replace() to work, with several simple
patterns but when i use preg_match_all, i either get unintended results
or incomplete matches.
any assistance in matching all "\*{2}\d+" from the above string would
be appreciated.
