Thanks Guys
I found out the solution, it may not be short but its working fine perfectly,
if you any other shorter one let me know

# get the line no of unique parameter ie Number
lineNo=`grep -n Number $fileName | awk -F":" '{print $1}'`
# Next line no
lineNo=`expr $lineNo + 1`

# get the current value in next value
curValue=`sed -n "${lineNo}p" $fileName | awk -F">" '{print $2}' | awk -F"<" '{print $1}'`
nextValue=`expr $curValue + 1`

rm -f temp.xml
# replace in that line only, and create a new file as sed does not change in original fiel
sed "$lineNo s/$curValue/$nextValue/" $fileName > temp.xml
rm -f $fileName
mv temp.xml $fileName

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION

OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
