Python解析论文中特定格式的引用

Question

我有这样的短信清单：

inp = """Something at the beginning

References
1. Ryff, C.D. (2014) Psychological Well-Being Revisited: Advances in the Science and Practice of Eudaimonia. 
2. Deci, E.L. & Ryan, R.M. (2002) Self-determination research: reflections and future directions.

Something at the end

Something else at the end"""

“其他参考”部分出现在一些文本中，在另一些文本中，下一部分以“好的参考资料”开始。同样，文本中的任何地方都可能出现类似的字符串。所有引用字符串有时用'\n‘分隔，有时仅用空格分隔。此外，'\n‘可能发生在文本中的任何地方，就在引用字符串的中间。

我需要regex在re.findall中使用，并在如下字符串列表中的“引用”之后返回所有字符串：

['Ryff, C.D. (2014) Psychological Well-Being Revisited: Advances in the Science and Practice of Eudaimonia.', 'Deci, E.L. & Ryan, R.M. (2002) Self-determination research: reflections and future directions.', 'Acedo, F. J., & Casillas, J. C. (2005). Current paradigms in the international management field.']

但只在“引用”之后，而不是在前面或后面的任何地方。

有人建议我使用这个正则表达式：

refs = re.findall(r'^References\s+((?:\d+\.\s*.*?\n)+)', inp, flags=re.M|re.S)
data = ''.join(refs)
output = re.findall(r'\d+\.\s*(.*?)\n', data)
print(output)

但是，只有当引用字符串被'\n‘分隔时，它才能工作--这在某些文本中不是这样。文本中的任何地方都可能出现“\n”。我根本不需要这些“\n”，这样它们就可以从文本中删除了。

当建议的regex不起作用时，示例：

inp = """Something at the beginning

Something at the end

Something else at the end"""

有谁能给我建议一个代码来帮助我获得参考的列表吗？

Answer 1

我认为这个代码可以解决你的问题

refs = re.findall(r'(?<=References\s)+((?:\d+\.\s*.*?\n)+)[^.\s]*', inp, flags=re.M|re.S)
    data = ''.join(refs)
    output = re.findall(r'\d+\.\s*(.*?)\n', data)
    print(output)
