python--正則匹配首尾標簽中間的內容

import re

it = re.finditer(r"<url>.*?</url>", '被篩選字符串')   # 匹配url標簽里的內容
# it = re.finditer(r"<command>.*?</command>", con)   # 匹配標簽里的內容，有換行符\n導致匹配失敗
it2 = re.finditer(r"<command>[\s\S]*?</command>", '被篩選字符串')   # 成功匹配方法1
# it = re.finditer(r"<command>[\d\D]*?</command>", con)  # 成功匹配方法2

for match in it:
   ret = match.group()
   print(ret)
for match in it2:
   ret = match.group()
   print(ret)
