in reply to regexp with Hash dout

See [untitled node, ID 1080191], and replies, posted under a different user name.

Questions containing the words "doesn't work" (or their moral equivalent) will usually get a downvote from me unless accompanied by:
  1. code
  2. verbatim error and/or warning messages
  3. a coherent explanation of what "doesn't work actually means.
