我有一个文本块,还有数千个,其中包含一些研究的引用。其中一个示例如下所示:
txt = '<div>1. <em>Nationella riktlinjer för rörelseorganens sjukdomar</em> (Swedish National Guidelines). 2012, The National Board of Health and Welfare. doi:10.1097/BRS.0b013e31829ff095 https://www.socialstyrelsen.se/publikationer2012/2012-5-1</a></div><div>2.

这个文本包含了doi的几个链接和键。我怎样才能得到所有这些,也许是在一个列表中,比如
['doi:10.1097/BRS.0b013e31829ff095',
'https://dx.doi.org/10.1016/j.arth.2005.04.023',
'https://dx.doi.org/10.1016/j.arth.2005.04.023',
'https://dx.doi.org/10.1186/s13018-017-0552-9',
]
我已经查找了几个相同的正则表达式,但无济于事。如:
import re
exp = "10.\\d{4,9}/[-._;()/:a-z0-9A-Z]+"
pattern = re.compile(exp)
pattern.findall(txt)
这将返回一个空列表。

多亏了@ wiktor-stribiew,我才让它工作起来。
