xml格式的问题
XmlDocument myDoc = new XmlDocument();
  //加载XML文件
  myDoc.Load(FileName);
  XmlTextWriter xtw = new XmlTextWriter(System.Web.HttpContext.Current.Server.MapPath("bcastr.xml"), Encoding.UTF8);//xml的生成路径
  xtw.Formatting = Formatting.Indented;
  xtw.WriteStartDocument();
  xtw.WriteStartElement("pie"); //节点 == topStories
  //xtw.WriteAttributeString("autoPlayTime", "6");
  string strSql = "SELECT * from dbo.Table_12";
  DataSet ds = db.dataSet(strSql);
  int max = ds.Tables[0].Rows.Count;
  for (int i = 0; i < max; i++)
  {
  if (ds.Tables[0].Rows[i]["photo"].ToString().Trim() == string.Empty)
  {
  continue;
  }
  xtw.WriteStartElement("slice");//==story1
  xtw.WriteAttributeString("title",ds.Tables[0].Rows[i]["photo"].ToString());//== imageURL
  xtw.WriteEndElement();
  }
  xtw.WriteFullEndElement();
  xtw.Close(); 






生成的是
<?xml version="1.0" encoding="utf-8" ?> 
- <pie>
  <slice title="111" /> 
  <slice title="222" /> 
  <slice title="333" /> 
  <slice title="444" /> 
  </pie>
 
 
但是我想要
 
<?xml version="1.0" encoding="utf-8" ?>
-<pie> 
  <slice title="111">19544</slice>
  <slice title="222">154</slice>
</pie>

------解决方案--------------------
xtw.WriteAttributeString("title",ds.Tables[0].Rows[i]["photo"].ToString());//== imageURL
xtw.WriteString("xxxx");
xtw.WriteEndElement();
