Assuming you have a loop like
while( <> ) {
}
you could say
while( <> ) {
next if /^\s*$/;
}
That will find a line that contains any number of whitespace characters, or
no characters at all. Note that you do need the ^$ characters to make sure
it matches the whole string; otherwise, you would match any string.

Subject: DELETE BLANK LINE
Hi all, I am sure someone has already asked this but I do not remeber
the answer. How can I delete or go to the next line if a blank line is
found. By a blank line I mean any line containing only white spaces,
return, tab characters etc.
Regards,
Pedro
