append 在 xml 文檔中具有 foreach 循環的多個數據集

Question

我正在為 Unity 使用 C# 編程。 我的目標是根據屬性（“ftProtect”、“ftWarn”、“ftWarn2”）在我的 XML 文件中找到某些節點，創建新文件並將數據集（內容）放在那里。 對於每個屬性，所有數據集（Name="Feldsatz1"/Name="Feldsatz2"）都應該在同一個文件中，但我的代碼只是將第一個數據集放在那里。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.Xml;
using UnityEngine.UI;
using System;
using System.Xml.Linq;

public class XML_divide : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        //Load XML - File
        TextAsset txtXmlAsset = Resources.Load<TextAsset>("Feldsatz");
        //New Doc for the Text  
        XmlDocument doc = new XmlDocument();
        //Pass in the Text
        doc.LoadXml(txtXmlAsset.text);

        XmlNodeList xnList = doc.SelectNodes("/AreaList/Area/FieldList/Field[@Type]");

        var feldsatznummer_ftProtect = 0;
        var feldsatznummer_ftWarn = 0;
        var feldsatznummer_ftWarn2 = 0;


        foreach (XmlNode node1 in xnList)
        {
            if (node1.Attributes["Type"].Value == "ftProtect")
            {
                var innerXml_ftProtect = node1.InnerXml;
                Debug.Log(innerXml_ftProtect);
                feldsatznummer_ftProtect = feldsatznummer_ftProtect + 1;
                XmlDocument doc_save = new XmlDocument();
                doc_save.LoadXml(innerXml_ftProtect);
                doc_save.Save(@"C:\Users\micha\Desktop\Thesis\Unity\ganzes Projekt_2\Assets\Resources\ftProtect" + "_" + feldsatznummer_ftProtect + ".xml");

            }
        }

        foreach (XmlNode node2 in xnList)
        {
            if (node2.Attributes["Type"].Value == "ftWarn")
            {
                var innerXml_ftWarn = node2.InnerXml;
                Debug.Log(innerXml_ftWarn);
                feldsatznummer_ftWarn = feldsatznummer_ftWarn + 1;
                XmlDocument doc_save = new XmlDocument();
                doc_save.LoadXml(innerXml_ftWarn);
                doc_save.Save(@"C:\Users\micha\Desktop\Thesis\Unity\ganzes Projekt_2\Assets\Resources\ftWarn" + "_" + feldsatznummer_ftWarn + ".xml");

            }
        }

        foreach (XmlNode node3 in xnList)
        {
            if (node3.Attributes["Type"].Value == "ftWarn2")
            {
                var innerXml_ftWarn2 = node3.InnerXml;
                Debug.Log(innerXml_ftWarn2);
                feldsatznummer_ftWarn2 = feldsatznummer_ftWarn2 + 1;
                XmlDocument doc_save = new XmlDocument();
                doc_save.LoadXml(innerXml_ftWarn2);
                doc_save.Save(@"C:\Users\micha\Desktop\Thesis\Unity\ganzes Projekt_2\Assets\Resources\ftWarn2" + "_" + feldsatznummer_ftWarn2 + ".xml");

            }
        }
    }
}

原裝 Xml 文件：

            <Field Type="ftWarn2" />
        </FieldList>
    </Area>
</AreaList>

Output ftProtect 文件（示例）：

    <UserPoint Contour="FALSE" Distance="57" Angle="0" />

            XDocument newDoc = null;

            foreach (XElement area in areas)
