I can not add a node in a XML file

Question

I have this code:

XmlDocument doc = new XmlDocument();
doc.Load(file_data);
XmlNamespaceManager namespace_xml = new XmlNamespaceManager(doc.NameTable);

//adicionar todos os namespaces necessarios
foreach (KeyValuePair namespace_elem in all_namespaces)
{
    namespace_xml.AddNamespace(namespace_elem.Key, namespace_elem.Value);
}

XmlNodeList node_list = doc.DocumentElement.SelectNodes("//w:tr//w:tc//w:p", namespace_xml);
Regex rgx = new Regex(@"^\{\{[a-zA-Z0-9_]+\}\}$");

for (int i = 0; i < node_list.Count; i++)
{
    XmlNode node_elem = node_list[i];
    Match mtch = rgx.Match(node_elem.InnerText);

    if (mtch.Success)
    {
        //caso seja uma linha que tenha de ser inserida
        XmlNode ancestor_node = null;
        XmlNode aux_node_elem = node_elem;

        while(aux_node_elem.ParentNode != null)
        {
            if (aux_node_elem.ParentNode.Name.Equals("w:tr"))
            {
                ancestor_node = aux_node_elem.ParentNode;
                break;
            }

            aux_node_elem = aux_node_elem.ParentNode;
        }

        ancestor_node.Clone();
        doc.Save(file_data);
        break;
    }
}

I want to find a node, in a XML file, whose text starts with "{{" and finishes with "}}" and duplicate his father. I can find that node but I can not duplicate his father. The following code is the XML that I want to use:



  
    
      
        
        
        
      
      
        
        
        
        
        
      
      
        
          
        
        
          
            
            
          
          
            
              Cabeçalho 1
            
          
        
        
          
            
          
          
            
              
            
            
              Cabeçalho 2

I try everything but I can not add a new node in the XML file. What did I make wrong?

You are ignoring the return value of ancestor_node.Clone();. It returns an XmlNode. Insert that one in the document again.
