    pattern = re.compile(r'(?=.*Door opened!)(?=.*Door closed!).*\n')

    segments = pattern.split(log_text)

    # 移除空字符串
    segments = [segment.strip() for segment in segments if segment.strip()]

如果最后一组没有Door closed，也会分成一组。

如果最后一组没有Door closed，则丢弃最后一条数据：

    pattern = re.compile(r'Door opened!(.*?)Door closed!', re.DOTALL)

    matches = pattern.findall(log_text)

    for match in matches:
