Monks, I'm struggling to find a solution to this seemingly simple problem. Please guide me towards salvation. There are two csv files of which I'm to convert File2 into nested XML. Handcoding the logic, as the library doesn't have the required modules.

File 1 -------
1,1234
3,2345


File 2 ---------
1234,ABC,10
2345,PQR,34
2345,XYZ,37
2345,LMN,14

I am to process File2 using File1 in iterative comparison, but I get the second line from File2 repeated 3 times in the XML result, unlike what I expect

Output as I want it:
<tag1>1234</tag1>
  <tag1_1>ABC</tag1_1>
   <tag1_2>10</tag1_2>
</tag1>
<tag1>2345</tag1>
  <tag1_1>PQR</tag1_1>
  <tag1_2>34</tag1_2>
  <tag1_1>XYZ</tag1_1>
  <tag1_2>37</tag1_2>
  <tag1_1>LMN</tag1_1>
  <tag1_2>14</tag1_2>
</tag1>

I see only the line with PQR from File2 repeating all 3 times in the output now

This is my code: 
while (($line1 = <FILE1>) & ($line2 = <FILE2>))  {
@inv1 = split (',',$line1);
chomp (@inv1);

@inv2 = split (',',$line2);
chomp (@inv2);

if ($inv1[1] == $inv2[0])
 { 
   for ($i = 1; $i <= $inv1[0]; $i++)
     {  ## xml printing from file2
        $line2;
     }
 }

} ##while

What am I doing wrong?
