Python正則表達式re.compile搜索失敗

Question

我使用https://regex101.com/#python為regx搜索構建以下模式。 雖然它在構建器站點中工作正常，但它似乎在我的python腳本中失敗了。 回溯建議使用AttributeError: 'NoneType' object has no attribute 'group'

pattern_strings = ['address:(.*?)(?=\\nphone:)', 'Address(.*?)(?=\\nRegDate:)']
pattern_string = '|'.join(pattern_strings)
address_t = re.compile(pattern_string)
address_t2 = address_t.search(raw)            
if address_t2.group(0):
    address = address_t2.group(0)
if address_t2.group(1):
    address = address_t2.group(1)

Answer 1

在第二個替代表達式中， Address(.*?)(?=\\\\nRegDate:) ，您似乎想要. 匹配任何字符，包括換行符，這不是它的正常含義。

嘗試這個：

address_t = re.compile(pattern_string, re.DOTALL)
