how to print the output in certain order?

I am trying to extracting the data from xml and print it certain order but i couldnt able to print in that order

Input Xml

 <xml>
 <service>
 <title>split xml</title>
 <main>
 <doc id="001">
 <title>doc1</title>
 <delt id="0001">
 <title>delt1</title>
  <text>num1</text>
 </delt>
 <delt id="0002-A">
 <title>delt2</title>
  <text>num1</text>
 </delt>
 </doc>
 <doc id="002">
 <title>doc2</title>
 <delt id="0003">
 <title>delt3</title>
  <text>num1</text>
 </delt>
 <delt id="0004">
 <title>delt4</title>
 <text>num1</text>
  </delt>
 </doc>
 </main>
 </service>
 </xml>

output printing in this order 0001 delt1 0002-A delt2 0003 delt3 0004 delt4

output needed

delt1   0001    
delt2   0002-A
delt3   0003    
delt4   0004

This is my Code

use File::Find;
use XML::LibXML;
use Data::Dumper;
my $path = "data.xml";
my $parser = XML::LibXML->new;
my $dom = $parser->parse_file($path) or die;
for my $sample ( $dom->findnodes('//delt/@id|//delt/title') ) {
print $sample->textContent(),"\t";  
print "\n";

}

Thanks in advance
