I used this also...

x=`grep -n "Cluster Resource Groups ===" test123.txt | cut -d ":" -f1`
y=`grep -n "Cluster Resource ===" test123.txt | cut -d ":" -f1`
a=`echo ${x} + 1 | bc`
b=`echo ${y} -1 | bc`
echo $x $y $a $b
sed -ne "${a},${b}p" test123.txt

But its giving me this error -->
syntax error on line 1, -1
sed: Function syntax error on line 1, ,-1p cannot be parsed.

The sed command is your answer and you can use text to start and stop the print function.
Code:
sed -n '/Cluster Resource Groups ===/,/Cluster Resource ===/p' test123.txt
