Question

我有一个xml文件，我想使用索引路径查询。我不确定它是否可能，但非常感谢任何帮助！

所以我要找的是能够用这样的路径查询xml文件。

ReturnState [0] \ ReturnDataState [0] \ Form6 [0] \体[0] \会员[0] \ FormA1

应该在第一个Member元素下给我FormA1。这种方法有很多原因而且没有太多细节，我想知道是否可以使用xpath或任何其他方式查询这样的东西。

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

Xpath拥有您需要遵循的自己的规范，它与您当前拥有的路径表达没有太大区别。这里重要的一些差异是，XPath索引从0开始而不是/，而XPath中的路径分隔符是\而不是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());。除非您乐意实现自己的解析器，否则最好稍微调整路径表达式以符合XPath语法：

<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>
