'''XML文件转txt'''
    import os
    import sys
    
    def xml2txt():
        try:
            import xml.etree.cElementTree as ET
        except ImportError:
            import xml.etree.ElementTree as ET
        dir = r"C:\Users\Ross\Desktop\2xml/"  # 读取路径尾端必须加反斜杠，否则报错
        f = open(r"C:\Users\Ross\Desktop\2xml.txt", 'w')
        for ii in os.listdir(dir):
            print(dir + ii)
            try:
                tree = ET.parse(dir + ii)  # 打开xml文档
                root = tree.getroot()  # 获得root节点
            except  Exception:
                print("Error:cannot parse file:" + ii)
                sys.exit(1)  # 主线程退出（0正常，1非正常）
            name = root.find('filename').text
            for object in root.findall('object'):
                bndbox = []          
                for i in range(4):
                    bndbox.append(int(object.find('bndbox').getchildren()[i].text))
                w = float(bndbox[2]) - float(bndbox[0])
                h = float(bndbox[3]) - float(bndbox[1])
                print(w, h)
                strss = "{0},{1},{2},{3},{4}".format(name, bndbox[0], bndbox[1], bndbox[2], bndbox[3], )
                f.write(strss + '\n')
    xml2txt()
    print("ok")

注：如果遇到报错 ModuleNotFoundError: No module named 'xml.etree'; 'xml' is not a package![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM5OTM4NjY2_size_16_color_FFFFFF_t_70][]

是因为下载的python当中，已经包含了xml.py文件，或者名为xml的文件夹。 [https://blog.csdn.net/qq280929090/article/details/78859858][https_blog.csdn.net_qq280929090_article_details_78859858]

如，改成如下就好了：
