regex - 获取包含在特殊字符 « 和 » 中的字符串之外的所有双引号字符

Question

我想从封闭字符 « 和 » 之外的所有子字符串中获取所有双引号，并将它们替换为转义字符后跟双引号，即。\"举个例子

输入字符串:

'The first generally recognized "wiki" application,«"WikiWikiWeb"», was created by American computer programmer "Ward Cunningham" in 1994'

预期输出:

'The first generally recognized \"wiki\" application,«"WikiWikiWeb"», was created by American computer programmer \"Ward Cunningham\" in 1994'

我尝试了以下代码。

string = '''The first generally recognized "wiki" application,«"WikiWikiWeb"», was created by American computer programmer "Ward Cunningham" in 1994'''

import re
arr = re.findall(r'(.*?)\«.*?\»', string)
for tag in arr :
 new_tag = tag.replace('"','\\"')
 string = string.replace(tag, new_tag)

Output: The first generally recognized \"wiki\" application,«"WikiWikiWeb"», was created by American computer programmer "Ward Cunningham" in 1994

这段代码的问题是正则表达式没有给我所有的子字符串，在本例中是第二个子字符串。预期结果必须是:

['第一个公认的“wiki”应用程序'，'，由美国计算机程序员“Ward Cunningham”于 1994 年创建']。

我想要正则表达式，它应该给我子字符串中的所有引号，而不是在封闭特殊字符之外的子字符串本身。

Answer 1

string = '''The first generally recognized "wiki" application,«blah"WikiWikiWeb"blah», was created by American computer programmer "Ward Cunningham" in 1994'''

import re
arr = re.findall(r'«.*?»|(".+?")', string)
for tag in arr :
  new_tag = tag.replace('"','\\"')
  string = string.replace(tag, new_tag)

print string

输出:

The first generally recognized \"wiki\" application,«blah"WikiWikiWeb"blah», was created by American computer programmer \"Ward Cunningham\" in 1994
