删除一组xml文件中两个标记之间的所有内容

import xml.etree.ElementTree as ET

def delete_content_between_tags(xml_file, start_tag, end_tag):
    tree = ET.parse(xml_file)
    root = tree.getroot()

    # 遍历XML文件中的元素
    for element in root.iter():
        # 找到起始标记
        if element.tag == start_tag:
            start_element = element
        # 找到结束标记
        elif element.tag == end_tag:
            end_element = element
            break

    # 删除两个标记之间的内容
    parent = start_element.getparent()
    start_index = parent.index(start_element)
    end_index = parent.index(end_element)
    del parent[start_index+1:end_index]

    # 保存修改后的XML文件
    tree.write(xml_file)

# 调用函数删除XML文件中两个标记之间的内容
delete_content_between_tags('example.xml', 'start_tag', 'end_tag')
