in thread 'one-liner' help

Wouldn't <br><br><\sbody> match <br><br></body> since \s matches any non-whitespace? Granted it would also match any <?body> where ? is any non-whitespace character, but that should not happen often in a html file I write. So the question is why it does not want to match some tag/text cut it and replace?

Here is the script:
perl -pe 's#.*(<div class="Content.*)</div></div></body>#$1#sgi' -i.bak test.html

Here is the test html file:

    \s matches whitespace.
    \S matches non-whitespace.

    Better to quote the backslash, if necessary, to match it explicitly.

      My bad. i got my \s and \S mixed up. But the script still does not work as stated above.

      Any ideas?

      Thanks.

        Any ideas?

        As it happens, yes. Note that   m#</div></div># will not match 

          </div>
  </div>

        because there's (vertical) whitespace between the two tags. You need \s* in your regex at points where whitespace is expected to appear between tags. And you need to slurp the entire file into memory first, since doing this line-by-line won't work.

        I've not tried it, but perlrun notes that -00 will force Perl into "paragraph" mode. Given your HTML, that might be sufficient. Otherwise, investigate the other options in perlrun.
