A variation of alister's sed solution with awk (and with a more ugly sample data file) :
Code:
awk '/START/ { m=""; ok=1; next } /END/ && ok { if (m) printf "%s", m; ok=0  } ok { m=m $0 "\n" }' data.txt

Sample data file
Code:
no
END
no
START
yes1
yes2
END
no
START
END
START
no
START
yes3
yes4
yes5
END
no
no
START
no
no

Output:
Code:
yes1
yes2
yes3
yes4
yes5

Hi Friends,

Thanks to all of u for ur spontaneous replies....
A small requirement added in my query is that...

A file is undergoing changes phase by phase...so I will comment the changes of respective phase as below
Code:
..............
..............

/* Start: Phase1/001 */
Hi
Hello
Yes
No
/* End: Phase1/001 */
...........
...........
...........
/* Start: Phase1/002 */
Yes
No
World
/* End: Phase1/002 */
.........
.........
/* Start: Phase2/001*/
Boys
Girls
Parents
Child
/* End: Phase2/001 */
.......
......

Now If I input the values of phase no(1,2,3...) and the modification no.(001/002/003....) in the respective phase, I have to get the output for those respective phase changes...

For Eg: If I input Phase:1 and modification no:2, I have to get the output as
Code:
/* Start: Phase1/002 */
Yes
No
World
/* End: Phase1/002 */

Try something like that :
Code:
phase=1
mod=002
awk -v pm="$phase/$mod" '
BEGIN {
    Start = "^/\\* Start: Phase" pm;
    End   = "^/\\* End: Phase" pm;
}
$0 ~ Start,$0 ~ End
' inputfile
