I am loading the content from an xml file using DOM. I am inserting some elements into the DOM. And now I am  writing the xml using perl XML::DOM::Node class's printToFile method. But i am not getting a properly structured  xml output. Can anyone suggest me about the options available in DOM parser perl module to write a structured xml?

I usually use XML::Twig to output the nice formatted XML.

Please see attached code for example
my $parser = new XML::DOM::Parser;
my $dom = $parser->parse($xml);
 
my $book = $dom->createElement("Book");
   $dom->getDocumentElement->appendChild($book);
my $twig = new XML::Twig;
   $twig->set_indent(" "x4);
   $twig->parse($dom->toString);
   $twig->set_pretty_print("indented");
#output
print $twig->sprint;

late to the party here, but you could use XML::LibXML too
use XML::LibXML;
 
# input is a file
my $input = 'some_file.xml';
# create the parser
my $parser = XML::LibXML->new();
 
# parse a file
my $doc = $parser->parse_file($xml);
# use parse_string() for a string of XML
 
my $filename = 'out.xml';
my $format = 1;
 
# print out the string of formatted XML
print $doc->toString(1);
 
# write to file a string of formatted XML
$doc->toFile($filename, $format);
