動態地將XML讀取到Datatable

我有下面的xml字符串，我試圖根據動態的一組列來查詢數據表。我對xml沒有任何控制權，它正從外部源傳入。動態地將XML讀取到Datatable

XML：

動態輸出所需的字段列表（這是正在從數據庫讀取，並且可以更改）：

ParameterName ParameterPath 
AdjusterEmail //MasterCarrierInfo//AdjusterEmail 
EmpCode   //MasterCarrierInfo//EmployerCode 
SOJ    //MessageBody//SOJ 
DOI    //MessageBody//DOI 
GPI    //MessageBody//Details//Detail//GPI 
BlockCode  //MessageBody//Details//Detail//Blocks//Block//BlockCode

我需要讀入一個表，看起來這像這樣：

AdjusterEmail     EmpCode SOJ DOI  GPI    BlockCode 
[email protected] 00000016 OH 20131006 75100*ndc 
[email protected] 00000016 OH 20131006 75100*ndc 
[email protected] 00000016 OH 20131006 123456789*ndc

每個MessageBody可以有多個詳細記錄，每個D可以有多個Block記錄etail

我真的不知道從哪裏開始，我已經嘗試了一堆不同的東西，包括LINQ（我不知道），並不能算出這個...

嘗試在後續步驟來使用： HTTP：/ /stackoverflow.com/questions/3458566/how-do-i-find-a-xml-node-by-path-in-linq-to-xml – W92 2014-09-29 22:17:34

你可以通過它t他將整個XML blob作爲SQL Server中的XML字段，然後使用XQuery從傳入的XML變量中進行選擇，並使用該語句在表中插入相應的值：http://msdn.microsoft.com/en-us /library/ms189075.aspx – 2014-09-29 22:19:30

@Jonathan Fields你解決了嗎？ – 2014-09-30 12:49:30

你可以簡單地用以下方法並傳遞XML文件路徑作爲輸入

DataSet ds = new DataSet(); 
ds.ReadXml("Your File Path");

你將不得不數據集將包含相應的DataSet對象爲XML。

它的工作原理：

XDocument xd = null; 
     using (StreamReader oReader = new StreamReader(xmlFilePath, Encoding.GetEncoding("ISO-8859-1"))) 
     { 
      xd = XDocument.Load(oReader); 
     } 

var records = from root in xd.Descendants("MessageBody") 
         from details in root.Elements("Details").Elements("Detail") 
         select new 
         { 
          AdjusterEmail = root.Element("AdjusterEmail").Value, 
          EmpCode = root.Element("MasterCarrierInfo").Element("EmployerCode").Value, 
          SOJ = root.Element("SOJ").Value, 
          DOI = root.Element("DOI").Value, 
          GPI = details.Element("GPI").Value, 
          BlockCode = details.Element("Blocks").Element("Block").Element("BlockCode").Value 

         };

創建數據表來保存記錄：

 DataTable dt = new DataTable(); 
     dt.Columns.Add("AdjusterEmail", typeof(string)); 
     dt.Columns.Add("EmpCode", typeof(string)); 
     dt.Columns.Add("SOJ", typeof(string)); 
     dt.Columns.Add("DOI", typeof(string)); 
     dt.Columns.Add("GPI", typeof(string)); 
     dt.Columns.Add("BlockCode", typeof(string)); 

     DataRow dr = null; 
     foreach (var readValue in records) 
     { 
      dr = dt.NewRow(); 
      dr["AdjusterEmail"] = readValue.AdjusterEmail; 
      dr["EmpCode"] = readValue.EmpCode; 
      dr["SOJ"] = readValue.SOJ; 
      dr["DOI"] = readValue.DOI; 
      dr["GPI"] = readValue.GPI; 
      dr["BlockCode"] = readValue.BlockCode; 
      dt.Rows.Add(dr); 
     }

DT包含如下：

AdjusterEmail    EmpCode SOJ DOI  GPI    BlockCode 
[email protected] 00000016 OH 20131006 75100*ndc 
[email protected] 00000016 OH 20131006 75100*ndc 
[email protected] 00000016 OH 20131006 123456789*ndc

這仍然只能帶回一條記錄。每個消息體可以有多個細節，每個細節可以有多個塊。請參閱上面編輯的xml。 – 2014-10-07 18:13:49

此外，字段列表是動態的，我正在從數據庫中讀取它們，因此下次可能會有其他字段或更少的字段。 – 2014-10-07 20:20:05

@JonathanFields現在它讀取所有細節節點 – 2014-10-08 05:01:23
