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文件修剪为包含其中特定字符串值的节点。
例如这个xml：
<CWeaponInfoBlob>
<SlotNavigateOrder>
<Item>
<WeaponSlots>
<Item>
<OrderNumber value="10" />
<Entry>SLOT_UNARMED</Entry>
</Item>
<Item>
<OrderNumber value="20" />
<Entry>SLOT_KNIFE</Entry>
</Item>
<Item>
<OrderNumber value="30" />
<Entry>SLOT_NIGHTSTICK</Entry>
</Item>
<Item>
<OrderNumber value="40" />
<Entry>SLOT_HAMMER</Entry>
</Item>
<Item>
<OrderNumber value="50" />
<Entry>SLOT_BAT</Entry>
</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>
我希望能够像“STUNGUN”一样将字符串传递给控制台，并让程序删除任何不包含该字的“Item”节点。
我已经成功完成了这项工作，但并不像我希望的那样。我有一个包含21,615行的XML文件，其中包含“武器”的定义。通过将“STUNGUN”传递给控制台，我希望它能做同样的事情，并删除没有包含输入单词的节点的任何节点（我猜父节点）。
Here's my xml file 如果你搜索单词“STUNGUN”，你会发现它的多个定义，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（不要判断代码，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，我花了几个小时来剪掉不需要的节点。
