用XmlTestWrite创建的XML中怎么创建兄弟节点？

Question

如题，比如：
- <HexStringInfo>
- <class name="类名">
- <aw name="aw名">
  <args name="参数名" type="类型名" protocol="<hexinfo protname="DataType" modulename="DATA-SRV-MSG" typename="STATUS-INFO-RECORD"/>" defaultvalue="001ff" /> 
  </aw>
  </class>
  </HexStringInfo>我想创建args节点的兄弟节点（下面红色部分），有没有直接的函数？或者用什么办法？
- <HexStringInfo>
- <class name="类名">
- <aw name="aw名">
  <args name="参数名" type="类型名" protocol="<hexinfo protname="DataType" modulename="DATA-SRV-MSG" typename="STATUS-INFO-RECORD"/>" defaultvalue="001ff" /> 
  <args name="参数名" type="类型名" protocol="<hexinfo protname="DataType" modulename="DATA-SRV-MSG" typename="STATUS-INFO-RECORD"/>" defaultvalue="001ff" /> 
  </aw>
  </class>
  </HexStringInfo>

fieldWriter.WriteStartElement("args");
            fieldWriter.WriteStartAttribute("name");
            fieldWriter.WriteString("参数名");            
            fieldWriter.WriteEndAttribute();            fieldWriter.WriteStartAttribute("type");
            fieldWriter.WriteString("类型名");
            fieldWriter.WriteEndAttribute();            fieldWriter.WriteStartAttribute("protocol");
            fieldWriter.WriteString("<hexinfo protname=\"DataType\" modulename=\"DATA-SRV-MSG\" typename=\"STATUS-INFO-RECORD\"/>\" defaultvalue=\"001ff");
            fieldWriter.WriteEndAttribute();            fieldWriter.WriteEndElement();            fieldWriter.WriteStartElement("args", "");
            fieldWriter.WriteStartAttribute("name", "");
            fieldWriter.WriteString("参数名");
            fieldWriter.WriteEndAttribute();            fieldWriter.WriteEndElement();
