使用C#解析XML [英] Parsing XML with C#

问题描述

我有一个XML文件，如下所示:

I have an XML file as follows:

我上传了XML文件: http://dl.dropbox.com /u/10773282/2011/result.xml .它是机器生成的XML，因此您可能需要一些XML查看器/编辑器.

I uploaded the XML file : http://dl.dropbox.com/u/10773282/2011/result.xml . It's a machine generated XML, so you might need some XML viewer/editor.

我使用此C#代码获取CoverageDSPriv/Module/*中的元素.

I use this C# code to get the elements in CoverageDSPriv/Module/*.

using System;
using System.Xml;
using System.Xml.Linq;

namespace HIR {
  class Dummy {

    static void Main(String[] argv) {

      XDocument doc = XDocument.Load("result.xml");

      var coveragePriv = doc.Descendants("CoverageDSPriv"); //.First();
      var cons = coveragePriv.Elements("Module");

      foreach (var con in cons)
      {
        var id = con.Value;
        Console.WriteLine(id);
      }
    }
  }
}

运行代码，我得到这个结果.

Running the code, I get this result.

hello.exe6144008016161810hello.exehello.exehello.exe81061hello.exehello.exe!17main_main40030170170010180180011190190012200200013hello.exe!107testfunctiontestfunction(int)40131505001460600158080216120120017140140018AA

我希望得到

hello.exe
61440
...

但是，我只得到一行长字符串.

However, I get just one line of long string.

• Q1:有什么问题吗?
• Q2:如何获取缺点中的元素数?我尝试了cons.Count，但是没有用.

• Q3:如果需要获取<CoverageDSPriv><Module><ModuleNmae>的嵌套值，请使用以下代码:

• Q1 : What might be wrong?
• Q2 : How to get the # of elements in cons? I tried cons.Count, but it doesn't work.

• Q3 : If I need to get nested value of <CoverageDSPriv><Module><ModuleNmae> I use this code :

var coveragePriv = doc.Descendants("CoverageDSPriv"); //.第一的(); var cons = coveragePriv.Elements("Module").Elements("ModuleName");

var coveragePriv = doc.Descendants("CoverageDSPriv"); //.First(); var cons = coveragePriv.Elements("Module").Elements("ModuleName");

我可以接受这一点，但是如果元素是深层嵌套的，那么我可能想要直接获取元素的方法.还有其他方法吗?

I can live with this, but if the elements are deeply nested, I might be wanting to have direct way to get the elements. Are there any other ways to do that?

var cons = coveragePriv.Elements("Module").Elements();

解决了此问题，但是对于NamespaceTable，它再次将所有元素打印在一行中.

solves this issue, but for the NamespaceTable, it again prints out all the elements in one line.

hello.exe
61440

或者，Linq to XML可能是更好的解决方案，例如这篇文章.

Or, Linq to XML can be a better solution, as this post.

推荐答案

在我看来，您只有一个名为Module的元素-因此.Value只是向您返回整个元素的InnerText.您是要这样做吗?

It looks to me like you only have one element named Module -- so .Value is simply returning you the InnerText of that entire element. Were you intending this instead?

coveragePriv.Element("Module").Elements();

这将返回Module元素的所有子元素，这似乎就是您想要的.

This would return all the child elements of the Module element, which seems to be what your'e after.

更新:

<NamespaceTable>是<Module>的子元素，但是您似乎想像<Module>一样处理它，因为您要写出每个子元素.因此，一种蛮力的方法是为<NamespaceTable>添加另一个循环:

<NamespaceTable> is a child of <Module> but you appear to want to handle it similarly to <Module> in that you want to write out each child element. Thus, one brute-force approach would be to add another loop for <NamespaceTable>:

foreach (var con in cons)
{
    if (con.Name == "NamespaceTable") 
    {
        foreach (var nsElement in con.Elements()) 
        {
            var nsId = nsElement.Value;
            Console.WriteLine(nsId);
        }
    }
    else
    {
        var id = con.Value;
        Console.WriteLine(id);
    }
}

或者，您可能希望通过.Descendents()将它们完全归一化:

Alternatively, perhaps you'd rather just denormalize them altogether via .Descendents():

var cons = coveragePriv.Element("Module").Descendents();

foreach (var con in cons)
{
    var id = con.Value;
    Console.WriteLine(id);
}
