解析XElement

我是LINQ / XML的新手.我刚刚了解到语言集成查询可用于解析xml.我正在尝试解析以下XML结构,我需要帮助

=================================

<config>

<params>
  <tp name="abc">yes</tp>
  <tp name="aee">no</tp>
  <tp name="bbc">no</tp>
  <tp name="ccb">yes</tp>
</params>

<nits>
  <tn name="kjh">
    <min>44</min>
    <max>98</max> 
  </tn>

  <tn name="klm">
    <min>55</min>
    <max>88</max> 
  </tn>

  <tn name="hhh">
    <min>44</min>
    <max>98</max> 
  </tn>
</nits>

<params>
  <tp name="lml">no</tp>
  <tp name="rre">yes</tp>
  <tp name="rst">no</tp>
  <tp name="wee">yes</tp>
</params>

<nits>
  <tn name="adf">
    <min>44</min>
    <max>98</max> 
  </tn>

  <tn name="ddd">
    <min>42</min>
    <max>92</max> 
  </tn>

  <tn name="kjj">
    <min>92</min>
    <max>98</max> 
  </tn>
</nits>

</config>

=================================

需要的输出：

我的目标是通过文本文件或数据网格等中的类别将上述数据显示为键值对.

<Params>
abc : yes
aee : no
bbc : yes
...
...
...
...


<nits>

kjh: 44 , 98
klm: 55 , 88
...
...
kjj: 92 , 98
ddd: 42 , 92
...

到目前为止,我编写的代码是

static void QueryTheData(XDocument doc)
        {
            try
            {
                var a = doc.Descendants("config").Elements("params");
                var b = doc.Descendants("config").Elements("nits");

                var c = doc.Elements("tp");
                var d = doc.Elements("tn");

               /* to do :  parse the elements into key value pairs */
               /* Need hint or help to proceed to get key value pairs from xml data

            }
             catch(Exception e)
            {
                 ....
            }               
 }

还需要初学者的LINQ / XML C#的良好指针.

解决方法:

我想出了这个：

using System.Linq;
using System.Xml.Linq;
using System.Xml.XPath;
using System.IO;
using System;

public class Program
{
    public static void Main(string[] args)
    {
        using (var fs = new StreamReader("./test.xml"))
        {
            var doc = XDocument.Load(fs);

            var parms = doc.Root.XPathSelectElements("params/tp")
                .ToDictionary(el => el.Attribute("name").Value, el => el.Value);

            var nits = doc.Root.XPathSelectElements("nits/tn")
                .Select(el => new {
                        Name = el.Attribute("name").Value,
                        Min  = (int) el.Element("min"),
                        Max  = (int) el.Element("max")
                    }).ToList();

            foreach (var kvp in parms)
                Console.WriteLine("{0}: {1}", kvp.Key, kvp.Value);

            foreach (var nit in nits
                    .OrderBy(nit => nit.Name)
                    .ThenBy(nit => nit.Max))
            {
                Console.WriteLine("{0}: {1} {2}", nit.Name, nit.Min, nit.Max);
            }
        }
    }
}

这向您展示了一些成分,包括在集合类型中存储参数/尼特的不同方法.输出：

abc: yes
aee: no
bbc: no
ccb: yes
lml: no
rre: yes
rst: no
wee: yes
adf: 44 98
ddd: 42 92
hhh: 44 98
kjh: 44 98
kjj: 92 98
klm: 55 88
