Is there a sed variant of the one presented that would support multiple lines of this nature?

First, if your file is in Unix/Linux, then remove those "^M" characters by feeding it to the "dos2unix" command.

Code:

dos2unix your_file
od -bc your_file

The "od -bc" command prints an octal dump of the file contents; ensure that you do **not** see any "\r" characters after the dos2unix command has been run on your file.

Thereafter, for removing multi-line <script> tags plus their content, you could do something like so:

Code:

$
$
$ cat -n f36
     1  this is line 1
     2  this is line 2
     3  <script> the script tags
     4  and their contents span
     5  multiple lines
     6  in this case
     7  </script>
     8  this is line 8
     9  <script> begin and close tags on same line </script>
    10  this is line 10
    11  and this is <script> begin and close tags somewhere
    12  within the line, i.e. not at the
    13  beginning and end of
    14  the line </script> line 14
    15  final line number 15
$
$
$ perl -lne 'if (/^(.*?)<script>.*$/) {
               print $1;
               $in = 1;
             }
             if ($in and /^.*?<\/script>(.*?)$/) {
               print $1;
               $in = 0;
             } elsif (not $in) {print}
            ' f36
this is line 1
this is line 2

this is line 8

this is line 10
and this is
 line 14
final line number 15
$
$

If you could post a sample of your data file, then that should be helpful.
