Question

我编写了一个python代码，将包含内容的子元素插入到另一个更大的子元素中。它确实可以工作，但是问题是每个子元素由于某种原因两次插入。我检查了代码，但不确定为什么会发生，有人可以在代码中指出我的问题吗？我知道这不是最有效的方法，但我会尽快加以改进。
代码：

import random
import os
import xml.etree.ElementTree as ET
map_file = "D:\\Users\\micha\\Desktop\\ram-and-michael\\binaries\\data\\mods\\public\\maps\\scenarios\\TestML.xml"
units_file = os.listdir("D:\\Users\\micha\\Desktop\\ram-and-michael\\binaries\\data\\mods\\public\\simulation\\templates\\units") # all the units in the file. 
armies_types = ("athen", "brit", "cart", "gaul", "iber", "kush", "mace", "maur", "pers", "ptol", "rome", "sele", "spart")
map_tree = ET.parse(map_file)
army_list = [] # units that can spawn in a game
    army1 = generate_units() # returns a list of strings
    army2 = generate_units()
    flag = 10 # id 

    map_root = map_tree.getroot()
    Entites = map_tree.find("Entities")
    Entites = delete_Entitites(Entites)


    for unit in army1:
        Entity = ET.SubElement(Entites,"Entity", uid= str(flag))
        Template = ET.SubElement(Entity,"Template").text = "units/" + unit
        Player = ET.SubElement(Entity,"Player").text = "1" 
        Position = ET.SubElement(Entity,"Position",x="326.66935" ,z="321.1384")
        Orientation = ET.SubElement(Entity,"Orientation",y="2.35621")
        flag += 1
        Entites.append(Entity)
        print(flag)
    for unit in army2:

        Entity = ET.SubElement(Entites,"Entity", uid= str(flag))
        Template = ET.SubElement(Entity,"Template").text = "units/" + unit
        Player = ET.SubElement(Entity,"Player").text = "2"
        Position = ET.SubElement(Entity,"Position",x="326.66935" ,z="321.1384")
        Orientation = ET.SubElement(Entity,"Orientation",y="2.35621")
        flag += 1 
        Entites.append(Entity)
        print(flag)
    indent(map_root)

    map_tree.write(map_file,encoding = "utf-8",xml_declaration = True)

输出：

谢谢您的帮助！

Answer 1

创建子元素时，您指定了父元素，因此该子元素已添加到父元素中。

创建子元素后，您需要在以下行再次将其追加到父元素：

Entites.append(Entity)

因此您的SubElement将重复。

为什么我的Python代码将Subelement Twice插入到XML文件？
