python：用于匹配多行模式的正则表达式（应用于字符串的开头）

Question

I'm trying to create a pattern to match two lines in the following multi-line text:

Text of no interest.
TextOfInterest1, foobar of no interest
another foobar of no interest
AnotherText-of_Interest2 some foobar don't care

I need to match exactly TextOfInterest1 and AnotherText-of_Interest2 , note that there might be multiple lines between TextOfInterest1 and AnotherText-of_Interest2 . I don't know how I can apply ^ symbol more than once in a single pattern string?

Answer 1

Try this:

pat = r"^.*\n([-_\w]+).*\n.*\n([-_\w]+).*$"
string="""Text of no interest.
TextOfInterest1, foobar of no interest
another foobar of no interest
AnotherText-of_Interest2 some foobar don't care"""

re.search(pat,string).groups()

('TextOfInterest1', 'AnotherText-of_Interest2')
