您可以尝试使用this regex，

\\editable\[(.*?)\]{\\.*\{(.*?)\}}

代码：

text = "\\editable[blab]{\\textit{anna karenina}}"
pattern = r"\\editable\[(.*?)\]{\\.*\{(.*?)\}}"
match = re.search(pattern, text)

print(match.group(1))
print(match.group(2))

输出：

blab
anna karenina

更新-1：

要处理具有多个模式的文本，

import re

text = "\\editable[blab]{\\textit{anna karenina}} and \\editable[another]{\\xyz{some example}}"

pattern = r"\\editable\[(.*?)\]{\\(?:.*?)\{(.*?)\}}"
results = re.findall(pattern, text)

for result in results:
    square_bracket_content, flower_bracket_content = result
    print("Square bracket content:", square_bracket_content)
    print("flower bracket content:", flower_bracket_content)

输出：

Square bracket content: blab
flower bracket content: anna karenina
Square bracket content: another
flower bracket content: some example
