I have a file with the following text:

INPUT:

{B001:B001}
{B002:B002}
{B003:B003}
{B00kr:B004}
{B00krup:B005}
{B00krupa:B006}
{B007:B007}
{B008:B008}

and my code is producing the following output:

OUTPUT:

1:1:1
2:2:2
3:3:3
kr:4:
krup:5:
krupa:6:
7:7:7
8:8:8

i.e., for 4,5 and 6 the third value is missing, pls review the code and suggest me what to do.

CODE:

   while(<IN>) {
       if(/\{B00(.+?):B00(.+?)\}/){
         $values{$2} = $1;
         print "$1:$2:$values{$2}\n";
      }
   }
[download]

I guess, $values{$2} takes only numeric argument

But I need this to search with the $2 argument only, because I need to replace the text of an another file as

from

<x-ref refid="B00kr,B00krup,B00krupa">

to

<x-ref refid="B004,B005,B005">

It works for me. Execute the following:

@lines = qw(
{B001:B001}
{B002:B002}
{B003:B003}
{B00kr:B004}
{B00krup:B005}
{B00krupa:B006}
{B007:B007}
{B008:B008}
);

for (@lines) {
      if(/\{B00(.+?):B00(.+?)\}/){
         $values{$2} = $1;
         print "$1:$2:$values{$2}\n";
      }
}
__END__
