使用索引路徑查詢XMl

我有一個xml文件，我想查詢使用索引路徑。我不確定這是否可能，但非常感謝任何幫助！使用索引路徑查詢XMl

所以我在找的是能夠用這樣的路徑查詢XML文件。

ReturnState [0] \ ReturnDataState [0] \ Form6 [0] \車身[0] \會員[0] \ FormA1

應該給我的第一個成員元素下的FormA1。這種方法有很多原因，並且沒有深入細節，我想知道是否可以使用xpath或其他方式查詢這樣的內容。

<ReturnState> 
    <ReturnDataState> 
    <Form6>  
     <Body>  
     <Member> 
      <MemberName> 
      <BusinessNameLine1Txt>Mouser0</BusinessNameLine1Txt> 
      </MemberName> 
      <FormA1> 
      <PartI-SalesFactor> 
       <SalesDelOrShippedOutState>31754631</SalesDelOrShippedOutState> 
       <TotalSales> 
       <Wisconsin>31754631</Wisconsin>

你真的認爲你的標題說XMI（而不是XML）？ – DeanOC

我只問XMI是一個有效的標籤，如果它不是一個錯字，那麼你應該添加標籤到你的問題。 – DeanOC

的Xpath有它自己的規範，你需要遵循，這是不是從你目前擁有的路徑表達式太大的不同。這裏重要的一些差異是，XPath索引從1開始不是0，並且XPath中的路徑分隔符是/而不是\。更好地稍微調整你的路徑表達式符合XPath語法，除非你是快樂的實現自己的解析器：

var doc = XDocument.Load("path_to_your_file.xml"); 
var xpath = "ReturnState[1]/ReturnDataState[1]/Form6[1]/Body[1]/Member[1]/FormA1"; 
var result = doc.XPathSelectElement(xpath); 
Console.WriteLine(result.ToString());

Dotnetfiddle Demo

輸出：

<FormA1> 
    <PartI-SalesFactor> 
    <SalesDelOrShippedOutState>31754631</SalesDelOrShippedOutState> 
    <TotalSales> 
     <Wisconsin>31754631</Wisconsin> 
     <TotalCompany>1965873635</TotalCompany> 
    </TotalSales> 
    <SalesFactorTotal> 
     <Wisconsin>31754631</Wisconsin> 
     <TotalCompany>1965873635</TotalCompany> 
    </SalesFactorTotal> 
    <ApportionmentPercentage>0.000000</ApportionmentPercentage> 
    </PartI-SalesFactor> 
</FormA1>
