Question

我有以下XML

<entry_list version="1.0">
<entry id="sweet tooth">
  <ew>sweet tooth</ew>
  <hw>sweet tooth</hw>
  <fl>noun</fl>
  <def>
    <date>14th century</date>
    <dt>:a craving or fondness for sweet food</dt>
  </def>
</entry>
</entry_list>

我如何只展示“对甜食的渴望或喜爱”部分？ XML放在文本框中，但我希望文本框只显示渴望的行。

此外，如果我搜索不太具体的内容，例如“计算机”，则有许多定义。我如何选择最早的定义？这是计算机的XML

Answer 1

一步一步

如何首先编写一个c＃应用程序来读取xml？
选择所需的xml标记
显示出来。

在C＃中读取xml可以在http://www.c-sharpcorner.com/article/reading-and-writing-xml-in-C-Sharp/找到（流式）对于小型xml，更喜欢DOM（一次性全部读取），这样，它有点简单：http://csharp.net-tutorials.com/xml/reading-xml-with-the-xmldocument-class/

选择xml标签，在第一种情况下可以是for循环中的switch语句;或者就像在DOM情况下选择节点和属性一样简单。

在WPF中显示应该是最简单的。只需将此值传递给WPF。

希望有所帮助，

我应该在上面写评论，但随着公司合并，域名更改，我丢失了我的电子邮件地址。我没有足够的意见在SO中发表评论。所以回答这里。希望帮助你，也帮助我建立积分。

Answer 2

尝试像这样的xml linq：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;

namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XDocument doc = XDocument.Load(FILENAME);

            string word = "computer";

            List<XElement> computers = doc.Descendants("entry").Where(x => (string)x.Attribute("id") == word).ToList();

            var definitions = computers.Select(x => new {
                word = (string)x.Attribute("id"),
                definitions = x.Elements("def").Select(y => new {
                    dts = y.Elements("dt").Select(z => (string)z).ToList()
                }).FirstOrDefault()
            }).ToList();
        }
    }
}

从xml中获取单词的所有定义
