yes. these are not so big text file, with contents like this:

<some useless row>
<delimiter>
<some useful rows or empty lines (where empty lines contains only \n or spaces 
and/or tabs + \n>
<some useful rows>
<some useful rows or empty lines (where empty lines contains only \n or spaces 
and/or tabs + \n>
<some useful rows>
<some useful rows or empty lines (where empty lines contains only \n or spaces 
and/or tabs + \n>
<delimiter>
<useless rows>

AFAIK the first solution is to handle STDIN in a cycle and print process like 
you suggested, but I wanted to resolve this with regexp and without cycles.
So you are right, I wanted to match all the lines between --==--==--==--==--s 
except the above defined empty lines.
