Hi, I have a numbered list marked up with <nl>...</nl>. All items inside it are marked as <item>...</item>. I want to number these items sequentially, i.e., change the item tag to <item num="1">, <item num="2"> and so on. My code to do this is:

$no++;
$_ =~ s/<item>/'<item num="'.$no.'">'/egs;

In the output file I get the desired numbering but from the start to the end of file, the <item> tags are sequentially numbered. I want the count to restart everytime a new list <nl> is encountered. Any help!!!

Here is my complete code:

if (!@ARGV)
{
   print "\t Usage: perl $0 <filename>\n\n";
   exit(0);
}
open (F1, "<$ARGV[0]") || die ("Can't open the file $ARGV[0]. $!\n");
$out = $ARGV[0];
$out =~ s/(.+)\.(.+)/$1/;
$out = $out.".xml";
open (F2, ">$out") || die ("Can't open the file $out. $!\n");
while(<F1>)
{
   $no++;
   $_ =~ s/<item>/'<item num="'.$no.'">'/egs;
   print F2 $_;
}
close F1;
close F2;
