20100615 学习记录：Empty Element

在用XmlTextReader遍历读取xml各个结点的时候，因为需要记录下来所有text值对应的结点顺序，所以要相应记录结点的进出栈。

初始测试一切正常，后来发现如果xml中间有自关自闭的空结点的话XmlTextReader只把它作为普通element读入，这样的话，因没有读到空结点的endElement而会导致后面所有存储的结点顺序错位。

检查了一下 XmlTextReader的方法和属性，发现里面有个IsEmptyElement。试了一下果然酱紫就ok了！！

うれしい！！！！ゲロゲロゲロ～～　XDDD~

 

while  (reader.Read())  // read node
            {
                 switch  (reader.NodeType)
                {
                     case  XmlNodeType.Element:

                         bool  endTagFlag  =   false ;
                         if  (reader. IsEmptyElement)
                        {
                            endTagFlag  =   true ;
                        }

                         string  tempNode  =  reader.Name;
                         while  (reader.MoveToNextAttribute())
                        {
                            attributePama.Length  =   0 ;

                            attributePama.Append(tempNode);
                            attributePama.Append( " ( " );
                            attributePama.Append(reader.Name);
                            attributePama.Append( " ) " );

                            PushValue( " ATTRIBUTE " , attributePama.ToString(), reader.Value);                            
                        }

                         if  ( ! endTagFlag)
                        {
                            alNode.Add(tempNode);
                        } 

                         break ;

                     case  XmlNodeType.Text:

                        PushValue( " TEXT " ,  "" , reader.Value); 

                         break ;

                     case  XmlNodeType.EndElement:
                        alNode.RemoveAt(alNode.Count  -   1 );
                         break ;
