Regex删除所有类型的项目符号和数字或字符等

Question

我试图删除所有不同格式的项目符号，这基本上是我的情况:

c.2低于国际贫困线的就业人口，按性别和年龄分列(%)年龄:15岁以上责任低于国际贫困线的就业人口，按性别和年龄分列(%)年龄:15岁以上. 1低于国际贫困线的就业人口，按性别和年龄分列(%)年龄:15岁以上

1. 低于国际贫困线的就业人口，按性别和年龄分列(%)年龄:15岁以上1.2低于国际贫困线的就业人口，按性别和年龄分列(%)年龄:15岁以上1.1.1低于国际贫困线的就业人口，按性别和年龄分列(%)年龄:15岁以上5.6.2 (S.1.C.1)低于国际贫困线的就业人口，按性别和年龄分列(%)年龄:15岁以上5.6.2 (S.3)低于国际贫困线的就业人口，按性别和年龄分列(%)年龄:15岁以上5.6.2 (S.4.C.13)低于国际贫困线的就业人口，按性别和年龄分列(%)年龄:15岁以上

我想要一个正则表达式来删除项目符号，无论他们是什么形式，只有:就业人口低于国际贫困线，按性别和年龄(%)年龄:15+

我试图使用^(?:d+.)+d*s*，它工作得很好，但它只检测1。或者1.2或1.1.1，这是我想要的开始，所以它是正确的，但现在我的给定更改为这个。

提前谢谢你，旁注:我使用python3

Answer 1

^[a-zd+].(d+)?.?(d+)?(s(.*)s)?s+

Answer 2

可以使用

^(?:[a-z]|d+)(?:.d+)*.?s*(?:([^()]*)s*)?

• ^字符串起始
• (?:[a-z]|d+)匹配字符a-z或匹配1+数字
• (?:.d+)*可选重复.和1+数字
• .?匹配可选点
• s*匹配可选的空白字符
• (?:([^()]*)s*)?可选匹配部分(...)，后跟最佳空格

Regex演示

在替换中使用空字符串

如果圆括号之间的部分是给定的特定模式，即大写字符a - z后跟一个点和数字:

^(?:[a-z]|d+)(?:.d+)*.?s*(?:([A-Z].d+(?:.[A-Z].d+)*)s*)?

例子

import re
pattern = r"^(?:[a-z]|d+)(?:.d+)*.?s*(?:([^()]*)s*)?"
s = ("c.2  Employed population below international poverty line, by sex and age (%) Age: 15+n"
"b.1  Employed population below international poverty line, by sex and age (%) Age: 15+n"
"a.1  Employed population below international poverty line, by sex and age (%) Age: 15+n"
"1. Employed population below international poverty line, by sex and age (%) Age: 15+n"
"1.2  Employed population below international poverty line, by sex and age (%) Age: 15+ n"
"1.1.1 Employed population below international poverty line, by sex and age (%) Age: 15+ n"
"5.6.2 (S.1.C.1) Employed population below international poverty line, by sex and age (%) Age: 15+n"
"5.6.2 (S.3) Employed population below international poverty line, by sex and age (%) Age: 15+n"
"5.6.2 (S.4.C.13) Employed population below international poverty line, by sex and age (%) Age: 15+")
result = re.sub(pattern, "", s, 0, re.MULTILINE)
if result:
print(result)
