I have to update the value of a node by based on the value of one of its attributes.

<ReferenceID referenceIDType="FXDD">FXDDILN233</ReferenceID> For the above Tag. i want to edit the value FXDDILN233 based on the attribute value referenceIDType="FXDD"

I tried the below code: 
my $nodeset = $doc->findnodes("//*[name()='ReferenceID']"); 
  foreach my $node ($nodeset->get_nodelist) {  
   if ($node->hasAttribute("referenceIDType") == XML::LibXML::Boolean-
+>True) { 

    $RetVal = $node->getAttributeNode("referenceIDType")->getValue(); 
 if ($RetVal eq "FDD") { 
 print "Attribute VAL=@@@@@@@@@@@@"."$RetVal \n"; 
  $node->setData("$NodeVal"); 
 } 
    
   } 
  }
