In your example you're opening a filehandle named XML, so I assume you want to convert your input stream to xml format. If this is right we would like to see how the xml output is produced. Probably you're using a memory intensive way.

    Ok Let me make it more clear..Im fetching those variables from a flat file and printing it in the XML file. The order of printing of the variable will differ from how we are getting the variable.


    open (my $INFO, "<", "$File") or die("Cannot open the flat file $!");

    open(my $LOG,">>LOG_file") or die("Cannot open $!");

    open(my $XML,">xml_file") or die("Cannot open $!");

    while (defined(my $line2 = $INFO)) {

        $line2 =~ s/&/&amp;/g;

        print "$line2\n";

        my $segment = substr($line2,0,2);

        if($segment eq "00")


        my $Var1 = trim(substr($line2,40,8));


        if($segment eq "A0")


        $Var2 = trim(substr($line2,2,9));

        $Var3 = trim(substr($line2,14,3));

        $Var4 = trim(substr($line2,20,42));

        $Var5 = trim(substr($line2,62,30));

    and so on


        print XML "<Header>\n";

        print XML "<AAA>VAR1<\/AAA>\n";

        print XML "<BBB>VAR2<\/BBB>\n";

        print XML "<CCC>VAR3<\/CCC>\n";

      print XML "<DDD>VAR4<\/DDD>\n";

      print XML "<EEE>VAR5<\/EEE>\n";

        print XML "<Header>\n";

    close $LOG;

    close $XML;

    close $INFO;

    sub trim($)


       my $string = shift;

        $string =~ s/^\s+//;

       $string =~ s/\s+$//;

       return $string;


      How much data do you have to collect to decide in which order you can generate the xml? Do you have to collect all records of the input file? Do you only have to collect a sequence of segments to create a - let's call it - xml record? Sorry, but your excerpt didn't help?

      How big is the input file?


        I have to collect data from all the lines in the input file and then print it to the XML file.

        Actually the input file is huge,..but now for testing we are using a input file with 30 lines for which we are getting the error.
