M-x flush-lines will prompt your for a regexp that defines the lines you wish
to delete.  There is also M-x keep-lines.

Hmm.  Well, that would take a little elisp, using re-search-forward or
re-search-backward, and working like M-x replace-regexp or M-x
query-replace-regexp on the selected line.

There is also isearch-forward-regexp...
