sed may not be the right tool. How about the following perl one liner-

perl -ne 'print unless /^
This will print all lines, except those between and

How about this ?

sed '//,/<\/Manifest>/d' input > output

Hi,

With awk you can:

awk '//,/<\/Manifest>/ {flag=1}
{if (!flag) print ; flag=0} ' file_in > f_out

Hi,
Maybe you still use "sed" but put a "\" before the "/".

In Korn Shell,

The best to use if there are such characters is ";",

i.e.

cat kapilraj |sed -e "s;BAD BOY;GOODBOY;g"

Your problem is the while loop, I guess.

STARTREL and ENDREL might both contain multiple entries. If not, you can replace the while with an if. You even should replace the test with something like:
[ "0$STARTREL" -le "0$ENDREL" ]

There are more problems in this script, btw. So I would recommend looking at the solutions given so far. perl and awk are languages that have this problem solved easily, for instance:
awk '//,/<\/Manifest>/ {print}' < $FILE
