在自定义的类似HTML的结构中查找开始和结束标记

def find_start_end_tags(html):
    stack = []
    start_tags = []
    end_tags = []
    start_index = 0

    for i in range(len(html)):
        if html[i] == "<":
            stack.append(i)
        elif html[i] == ">":
            if stack:
                start_index = stack.pop()
                if html[start_index+1] != "/":
                    start_tags.append(html[start_index:i+1])
                else:
                    end_tags.append(html[start_index:i+1])

    return start_tags, end_tags

# 示例用法
html = "<div><p>Hello, World!</p></div>"
start_tags, end_tags = find_start_end_tags(html)
print("开始标记：", start_tags)
print("结束标记：", end_tags)

开始标记： ['<div>', '<p>']
结束标记： ['</p>', '</div>']
