      details
    </module>

the code is...

use XML::DOM;

my $xml_file = “./sample.xml”; 
my $parser = new XML::DOM::Parser; 
my $doc = $parser->parsefile($xml_file); 

my $module_node = $doc->getElementsByTagName(“module”); 
my $module1 = $module_node->item(0); 
my $module1_node = $module1->getElementsByTagName(“moduleref”); 

for(my $i=0;$i<$module1_node->getLength;$i++){
  my $node = $module1_node->item($i); 
  my $node_name = $node->getAttribute(“name”); 
  my $new_node = &getModule($node_name); 
  if($new_node){ 
    replace($node,$new_node); 
  }
  else{
    do nothing…
  }
}

sub getModule{

  my $module_name = shift; 
  for(my $i=1;$i<$module_node->getLength;$i++){
    my $sub_node = $module_name->item($i); 
    my $sub_node_name = $sub_node->getAtrribute(“name”); 
    if($module_name eq $sub_node_name){ 
      return $sub_node; 
    }
  }
}
