Expected output:


/<script>/ {
        # Change the first <script> in the line to \n.
        # We can be certain that there will not be a newline in the
        # initial pattern space, so this is unambiguous.
        # If the closing </script> is on the same line, change it also
        # to \n and delete everything in between, newlines inclusive.
        # If the result in an empty line, print nothing.
        /<\/script>/ {
                b empty?

        # The </script> element is not on the same line as its <script>.
        # Before moving on in search of it, delete from the newline to the
        # end of line.  Print only if the line is not empty.

        # Discard lines until closing </script> is found.
        /<\/script>/! b next

        # Change </script> to \n and delete preceding text.

        # If the line has been left empty, do not print a blank line.

        # In case there's another <script> element later in the line.
        b top

Descriptinator Test run:
$ sed -f descriptinator.sed testdata

Thank you Alister. It is working great. Most importantly it works for most of the cases especially when the starting and the ending tag are in same line.

Thanks again.
