我想閱讀下面的XML文件讀雙嵌套的XML

<Tabellen> 
<Header> 
    <Tables> 
     <Table>SW_RL</Table> 
      <Fields> 
       <Field>KeyVeld</Field> 
       <Type>Alpha</Type> 
       <Size>100</Size> 
       <SubType>st_none</SubType> 
      </Fields> 
      <Fields> 
       <Field>ErrorCode</Field> 
       <Type>Alpha</Type> 
       <Size>50</Size> 
       <SubType>st_none</SubType> 
      </Fields> 
      <Fields> 
       <Field>Description</Field> 
       <Type>Memo</Type> 
       <Size>100</Size> 
       <SubType>st_none</SubType> 
      </Fields> 
     </Tables> 
</Header> 
<Header> 
    <Tables> 
     <Table>SW_RH</Table> 
    <Fields>

    <Fields>

     <Type>Alpha</Type> 
     <Size>100</Size> 
     <SubType>st_none</SubType> 
    </Fields> 
    <Fields> 
     <Field>BillToAddress</Field> 
     <Type>Alpha</Type> 
     <Size>100</Size> 
     <SubType>st_none</SubType> 
    </Fields> 
    <Fields> 
     <Field>ShipToAddress</Field> 
     <Type>Alpha</Type> 
     <Size>100</Size> 
     <SubType>st_none</SubType> 
    </Fields> 
    <Fields>

     <Type>Alpha</Type> 
     <Size>100</Size> 
     <SubType>st_none</SubType> 
    </Fields> 
    <Fields>

     <Size>10</Size> 
     <SubType>st_none</SubType>  
    </Fields> 
    <Fields> 
     <Field>AdvanceBilling</Field> 
     <Type>Alpha</Type> 
     <Size>10</Size> 
     <SubType>st_none</SubType> 
    </Fields> 
    </Tables> 
</Header> 
</Tabellen> 

當前代碼

XmlDocument xmldoc = new XmlDocument(); 
xmldoc.Load(directory + "\\Server_Config.xml"); 
XmlNodeList xmlNodelist = null; 
XmlNodeList xmlNodelist2 = null; 

xmlNodelist = xmldoc.SelectNodes("Tabellen/Header/Tables"); 
foreach (XmlNode mnode in xmlNodelist) 
{ 
    MessageBox.Show(mnode["Table"].InnerText, "ok"); 
    //create table 

    xmlNodelist2 = xmldoc.SelectNodes("Tabellen/Header/Tables/Fields"); 
    foreach (XmlNode mnode2 in xmlNodelist2) 
    { 
     MessageBox.Show(mnode2["Field"].InnerText, "ok"); 
     // create fields 
    } 

} 

總的想法是創建2個表 表1:含3場 RL表2:包含12個區域的RH

但實際上結果是兩個表都包含15個區域

我在做什麼錯?

你是如何閱讀XML的? 'DataSet.ReadXML'? –

Linq2Xml更易於使用。

XDocument xDoc = XDocument.Load("myfile.xml"); 
var tables = xDoc.Descendants("Header") 
       .Select(h => new 
       { 
        Table = h.Descendants("Table").First().Value, 
        Fields = h.Descendants("Fields") 
           .Select(f=>new{ 
            Field = f.Element("Field").Value, 
            Type = f.Element("Type").Value, 
            Size = f.Element("Size").Value, 
            SubType = f.Element("SubType").Value 
           }) 
           .ToList() 
       }) 
       .ToList();

xmlNodelist2 = xmldoc.SelectNodes("Tabellen/Header/Tables/Fields"); 

應該

xmlNodelist2 = mnode.SelectNodes("Fields"); 

否則你在XML選擇所有字段,而不僅僅是當前桌子底下的人。

(但我沒有測試代碼)
