@ RudiC, in that case, why not either VLCV=$[ $VLCV + 1 ] or even just ((VLCV++))?

@ TiedCone:
Code:
C=0 # Counter
while [ $C -le $VLCV ]
do  echo "<vlc:item tid=\"$C\"/>"
    C=$(( $C + 1 ))
done

Hello Tiedcone,

Following may help you in same, not tested though.
Code:
 awk -vLINES=`cat Input_file | wc -l` 'BEGIN{B=0;C=0} /<vlc:id>/{A=$0;sub(/>.*/,">",$0);sub(/.*</,"<",A);S=S?S ORS $0 B A:$0 B A;print $0 B A;B++;next} /<extension application/{print $0 ORS S;next} 1' Input_file

Thanks,
R. Singh

So - it's in $VLCV, and you are echoing all the text? add
Code:
i=0
while [ "$i" -le "$VLCV" ]
  do echo "           <vlc:item tid=\"$i\"/>"
     i=$(expr $i + 1)
  done

to your script.

Thanks to all. Unfortuantelly I was not able to use above examples but I found another way to achieve my goal by using grep and sed. I just simply copied existing
Code:
<vlc:id>0</vlc:id>

strings and replaced what needs to be replaced. Smilie
