I am tried to remove one node with this code  below.

But it is removing all nodes with this tag

NodeList defectList = (NodeList) doc.getElementsByTagName("oslc_cm:tracksWorkItem");
   System.out.println("defectList.getLength() "+defectList.getLength());
   for(int i=defectList.getLength()-1;i>=0;i--){
    Element defect = (Element) defectList.item(i);
     String link=defect.getAttribute("rdf:resource");
     String id=link.substring(link.lastIndexOf("/")+1);
         if (id.equals(defectID))
     {
   
      defect.getParentNode().removeChild(defect); 
     
    //  doc.removeChild(defect);
   System.out.println("Removing defect "+ defectID);
   
     }
    
   
  }
