( #3333=superdoc: print w/replies, xml ) Need Help??

i have a tab delimited column file as shown

np np n_nom 3 {RP} {RP} paNiyappeVttirunna VM_RP V_RP o o o np np n_nom -3 {/RP} {/RP} np np n_nom 3 {RP} {RP} nammal VM_RP V_RP o o o np np n_nom -3 {/RP}

and there are many such sections seperated by a new line.i want to count the no.of sentences that has {RP} {RP} and {/RP} {/RP} occuring together.If the string is missing from either the 4th or 5th column then it should not be counted.

$countC = 0; while(<>) { chomp; @array = split(/\t/,$_); if($array[4] eq $array[5]) { foreach $item(@array){ if(($item =~ /{RP}/) && ($item++ =~ /{\/RP}/)) { $countC++; } } } } print"CorrectRP=>$countC\n";

    [Corion]: Hi choroba!
    [Corion]: And Discipulus!
    Corion arrived back from London. Always nice to meet people again, even if it's just once per year.
    [Corion]: Also, dk contributed some cool stuff to App::ShaderToy, like menu settings and real fullscreen, eliminating many of my #TO-DO comments ;)
    [Corion]: I hope you spent the four days well without me online ;-D
    [Discipulus]: more or less Corion: the monastery was so calm, maybe too much! i feared you'v lost in VR
