【问题描述】：

我是新来的，如果我做错了，请原谅。

我有一系列具有不同 XML 节点定义的不同 XML 文档。我正在尝试创建一个实用的控制台应用程序，它允许我将任何 xml 文件修剪为其中包含特定字符串值的节点。

例如这个xml：

<CWeaponInfoBlob>
    <SlotNavigateOrder>
        <Item>
            <WeaponSlots>
                <Item>

                </Item>
                <Item>
                    <OrderNumber value="60" />
                    <Entry>SLOT_CROWBAR</Entry>
                </Item>
                <Item>
                    <OrderNumber value="70" />
                    <Entry>SLOT_GOLFCLUB</Entry>
                </Item>
                <Item>
                    <OrderNumber value="90" />
                    <Entry>SLOT_PISTOL</Entry>
                </Item>
                <Item>
                    <OrderNumber value="100" />
                    <Entry>SLOT_COMBATPISTOL</Entry>
                </Item>
                <Item>
                    <OrderNumber value="110" />
                    <Entry>SLOT_PISTOL50</Entry>
                </Item>
                <Item>
                    <OrderNumber value="120" />
                    <Entry>SLOT_APPISTOL</Entry>
                </Item>
                <Item>
                    <OrderNumber value="130" />
                    <Entry>SLOT_STUNGUN</Entry>
                </Item>
            </WeaponSlots>
        </Item>
    </SlotNavigationOrder>
</CWeaponInfoBlob>

我希望能够将字符串传递给控制台，例如“STUNGUN”，并让程序删除任何不包含该单词的“项目”节点。

我已经成功地完成了这件事，但不是我想要的那样。我有一个包含 21,615 行的地狱般的 XML 文件，其中包含“武器”的定义。通过将“STUNGUN”传递给控制台，我希望它做同样的事情并删除任何没有包含输入单词的节点的节点（我猜是父节点？？）。

Here's my xml file 如果你搜索“STUNGUN”这个词，你会发现它有多个定义，我希望程序只保留那些节点（和兄弟节点！！）。我该怎么做呢？

这是我尝试过的（不要评判代码，我在 5 年的编程中从未做过这样的事情，显然它不起作用）：

using System;
using System.IO;
using System.Linq;
using System.Text;
using System.Xml;

namespace XmlUtil
{
    class Program
    {
        static void Main(string[] args)
        {
            if (args.Length <= 0)
                return;

            if (!args.All(i => i.EndsWith(".meta")) && !args.All(i => i.EndsWith(".xml")))
                return;

            try
            {
                for (int x = 0; x < args.Length; x++)
                {
                    var arg = args[x];

                    Console.WriteLine("Enter a string value:");
                    var userInput = Console.ReadLine();

                    var xml = new XmlDocument();
                    xml.Load(arg);
                    var nodes = xml.GetElementsByTagName("*");
                    var ienum = nodes.GetEnumerator();

                    XmlDocument newDoc = new XmlDocument();
                    while(ienum.MoveNext())
                    {
                        XmlNode node = (XmlNode)ienum.Current;
                        if (node.InnerText.Contains(userinput))
                        {
                            newDoc.ImportNode(node, false);
                        }
                    }
                    // Then write it to a file...
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message + Environment.NewLine + ex.StackTrace);
                Console.ReadLine();
            }

            Console.WriteLine("Press [Enter] to exit...");
            Console.ReadLine();
        }
    }
}

编辑：我想补充一点，这是手动完成的，我花了几个小时才剪掉不需要的节点。

请注意，SCICARBINE 的 <Item type="CWeaponInfo"> 尚未删除，因为它有一个节点包含 SCICARBINE 一词，因此它和它的兄弟姐妹都保留了下来。

【问题讨论】：

你考虑过使用 Linq to XML 吗？ docs.microsoft.com/en-us/dotnet/csharp/programming-guide/… 这将允许您将 XML 文档视为另一个 IEnumerable 并针对它编写简单的查询。现在无法编写示例，因为我不在电脑旁。
嗯，所以用Linq重新构造xml？听起来很有趣，我将不得不做更多的研究。当您有机会时，将不胜感激一个不错的代码示例！谢谢！ :)

标签： c# xml console-application

【解决方案1】：

对第一个请求使用 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);

            List<XElement> removeNodes = doc.Descendants("WeaponSlots").Descendants("Item").Where(x => !x.Descendants("Entry").Where(y => (string)y == "SLOT_STUNGUN").Any()).ToList();
            foreach (XElement removeNode in removeNodes)
            {
                removeNode.Remove();
            }

        }
    }
}

第二次请求

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";
        const string ADD_FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {

            XDocument doc = XDocument.Load(FILENAME);
            XDocument addDoc = XDocument.Load(ADD_FILENAME);

            XElement docRoot = doc.Root;
            XElement addRoot = addDoc.Root;

            foreach (XElement child in addRoot.Elements())
            {
                string elementName = child.Name.LocalName;

                XElement docElement = docRoot.Element(elementName);

                docElement.Add(child.FirstNode);
            }


        }
    }
}

【讨论】：

好的，现在开始有意义了。老实说，只要删除没有我想要的文本的节点，手动定义后代就没有问题。 @jdwengspan>
是的，工作正常。我要买它。谢谢！！你为我节省了很多时间。
添加了第二个请求。我花了几分钟才把它弄对了。
