我尝试使用 Python 和 Re 来匹配段落。
文本示例:
Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum.
two or more line breaks here
Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet.
two or more line breaks here
Ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet.
这个表达式似乎几乎可以完成工作:
paragraphs = re.findall(r'(?s)((?:[^\n][\n]?)+)', textContent)
但我想确保仅在有两个或更多换行符时才匹配。目前匹配得太频繁了。

1 SDVSDRG:
**here are two line-breaks, but dont split this paragraph**
**at the momemnt it breaks here, but it shouldnt**
a. wevvdfvdfd
b. sdfsdfsdfsdfsdfsdghtrhrth
最佳答案
查看 RegEx101 上的这个正则表达式 (?m)(?:.+(?:\n.)?)+ ，您还可以在其中获得其解释。
使用此正则表达式的示例 Python 代码:
import re
import pprint
textContent = '''Lorem ipsum dolor sit amet, consetetur sadipscing elitr,
sed diam nonumy eirmod tempor invidunt ut labore et dolore
magna aliquyam erat, sed diam voluptua. At vero eos et
accusam et justo duo dolores et ea rebum.
Stet clita kasd gubergren, no sea takimata sanctus est Lorem
ipsum dolor sit amet.
Ipsum dolor sit amet, consetetur sadipscing elitr, sed diam
nonumy eirmod tempor invidunt ut labore et dolore magna
aliquyam erat, sed diam voluptua. At vero eos et accusam et
justo duo dolores et ea rebum. Stet clita kasd gubergren, no
sea takimata sanctus est Lorem ipsum dolor sit amet.
ART. WEFWEFEW
1 SDVSDRG:
a. wevvdfvdfd
b. sdfsdfsdfsdfsdfsdghtrhrth'''
pprint.pprint(re.findall(r'(?m)(?:.+(?:\n.)?)+', textContent))
输出:
['Lorem ipsum dolor sit amet, consetetur sadipscing elitr,\n'
'sed diam nonumy eirmod tempor invidunt ut labore et dolore\n'
'magna aliquyam erat, sed diam voluptua. At vero eos et\n'
'accusam et justo duo dolores et ea rebum.',
'Stet clita kasd gubergren, no sea takimata sanctus est Lorem\n'
'ipsum dolor sit amet.',
'Ipsum dolor sit amet, consetetur sadipscing elitr, sed diam\n'
'nonumy eirmod tempor invidunt ut labore et dolore magna\n'
'aliquyam erat, sed diam voluptua. At vero eos et accusam et\n'
'justo duo dolores et ea rebum. Stet clita kasd gubergren, no\n'
'sea takimata sanctus est Lorem ipsum dolor sit amet.',
'ART. WEFWEFEW\n'
' 1 SDVSDRG:\n'
' a. wevvdfvdfd\n'
' b. sdfsdfsdfsdfsdfsdghtrhrth']
