python - 在给定开始和结束标记的情况下，如何在 python 中删除子字符串？

Question

我有一个看起来像的刺痛：

u'\'\'\'Joseph Michael "Joe" Acaba\'\'\' (born May 17, 1967) is an [[Teacher|educator]], [[Hydrogeology|hydrogeologist]], and [[NASA]] [[astronaut]].<ref name="bio">{{Cite web|url=http://www.jsc.nasa.gov/Bios/htmlbios/acaba-jm.html|title=Astronaut Bio: Joseph Acaba|month=February | year=2006|publisher=[[NASA|National Aeronautics and Space Administration]]|author=NASA|accessdate=November 26, 2006}}</ref><ref name="bio2">{{Cite web|url=http://oeop.larc.nasa.gov/hep/hep-astronauts.html|title=NASA Hispanic Astronauts\n|publisher=National Aeronautics and Space Administration|author=NASA|accessdate=November 26, 2006}}</ref> In May 2004 he became the first person'

我想删除所有测试<ref以ref>包括标记。我是 python 新手，不确定最好的方法。

Answer 1

在这种情况下，正则表达式可以正常工作：

import re
ref = re.compile(u'<ref.*?ref>', re.DOTALL)

ref.sub(u'', yourtext)

注意re.DOTALL限定符；您的<ref>部分中有换行符，我们也想删除它们。

演示：

>>> import re
>>> tst=u'\'\'\'Joseph Michael "Joe" Acaba\'\'\' (born May 17, 1967) is an [[Teacher|educator]], [[Hydrogeology|hydrogeologist]], and [[NASA]] [[astronaut]].<ref name="bio">{{Cite web|url=http://www.jsc.nasa.gov/Bios/htmlbios/acaba-jm.html|title=Astronaut Bio: Joseph Acaba|month=February | year=2006|publisher=[[NASA|National Aeronautics and Space Administration]]|author=NASA|accessdate=November 26, 2006}}</ref><ref name="bio2">{{Cite web|url=http://oeop.larc.nasa.gov/hep/hep-astronauts.html|title=NASA Hispanic Astronauts\n|publisher=National Aeronautics and Space Administration|author=NASA|accessdate=November 26, 2006}}</ref> In May 2004 he became the first person'
>>> ref = re.compile(u'<ref.*?ref>', re.DOTALL)
>>> ref.sub(u'', tst)
