如何将多个xml文件附加到一个xml文件中

Question

我要附加的第一个文件是来自LabelImg的图像注释。有没有办法附加两个XML文件？我需要附加这些文件，将它们转换为CSV文件，用于交叉验证以进行对象检测

<annotation>
    <folder>business center</folder>
    <filename>bcenter (1).PNG</filename>
    <path>D:\RealTimeObjectDetection\Tensorflow\workspace\images\business center\bcenter (1).PNG</path>
    <source>
        <database>Unknown</database>
    </source>

        <width>1815</width>

            <ymax>533</ymax>
        </bndbox>

    <filename>bcenter (2).PNG</filename>
    <path>D:\RealTimeObjectDetection\Tensorflow\workspace\images\business center\bcenter (2).PNG</path>

是否有一个软件或代码可以使流程自动化？我有大约1405个文件

Answer 1

见下文（1.xml和2.xml是从问题中选取的示例）

想法是加载这两个文件并将它们嵌套在一个公共根目录下

import xml.etree.ElementTree as ET

root1 = ET.parse('1.xml').getroot()
root2 = ET.parse('2.xml').getroot()

root = ET.Element('annotations')
root.append(root1)
root.append(root2)
ET.dump(root)

输出

<?xml version="1.0" encoding="UTF-8"?>
