Hi, I'm using xml::writer trying to output the xml file from the csv input file. I'm not sure how to print the name as a separate tag. 
#input file

name    subname        start size
CAL_M    reserved        0    13
CAL_M    o_check_out    13    7
CAL_M    o_ttr_first    20    4
CAL_M    o_cal_check_1  24    4
PSQN_0    reserved       0    8
PSQN_0    check_final    8    10
PSQN_0    o_check       18    10

#expected output file

<structure name="CAL_M">
<value type = "13"name = "reserved" start = "0" </value>
<value type = "7" name = "o_check_out" start = "13"</value>
<value type = "4" name = "o_ttr_first" start = "20"</value>
<value type = "4" name = "o_cal_check_1"start = "24"</value>
</structure>

<structure name="PSQN_0">
<value type = "8" name = "reserved" start = "0" </value>
<value type = "10" name = "check_final"start = "8"</value>
<value type = "10" name = "o_check" start = "18" </value>        
</structure>

#current output file

<value type = "13"name = "reserved" start = "0" </value>
<value type = "7" name = "o_check_out" start = "13"</value>

Here's my code 
#input file
open (FILE,"<in.csv") || die "cannot open file: $!";
my @array =<FILE>;
close (FILE);

#output file
my $output_file = "myfile.xml";
my $output = new IO::File(">$output_file");

my $writer = new XML::Writer(OUTPUT=>$output, DATA_MODE=>1, DATA_INDEN
+T => 2);

#structure                    
foreach my $item(@array)
{
    chomp($item);
    $item =~/(\w+),(\w+),(\d+),(\d+)/;
    my $name =$1;
    my $sname=$2;
    my $start=$3;
    my $size =$4;

    $writer->startTag("structure", "name"=>$name);  
    $writer->startTag("value", "type"=>$size, "name"=>$sname, "start"=
+>$start);  
    $writer->endTag(); 
    $writer->endTag();
 }
$writer->end();
$output->close();
