python 函数正则获取tag 内容

import re


def extract_between_tags(tag: str, string: str, strip: bool = False) -> list[str]:
    ext_list = re.findall(f"<{tag}>(.+?)</{tag}>", string, re.DOTALL)
    if strip:
        ext_list = [e.strip() for e in ext_list]
    return ext_list


function_calling_message = "asdf<tr>this is forasp.cn</tr>"
match_data = extract_between_tags("tr", function_calling_message, True)
if len(match_data) > 0:
    print(match_data[0])
else:
    print("no match")
