python - 正则表达式可在更多条件下匹配版权声明中的公司名称

Question

一段时间以来，我一直在尝试找到一个强大的正则表达式来从版权声明中提取公司名称(并且对正则表达式了解不多)。

在这个问题中:Regex to match company names from copyright statements under several conditions

我得到了正则表达式:

(?i)(?:©(?:\s*Copyright)?|Copyright(?:\s*©)?)\s*\d+(?:\s*-\s*\d+)?\s*(.*?(?=\W*All\s+rights\s+reserved)|[^.]*(?=\.)|.*)

但是当我尝试更多的例子时，我发现这还不够。我想更改它，以便它也符合以下条件，同时仍然适用于之前的所有情况:

1. 请考虑到“©”或“版权”(以最后一个为准)之前可能会出现其他内容，请忽略它。

示例:

602-226-2389 ©2019 Endurance International Group.
Copyright 1999 — 2019 © Iflexion. All rights reserved.

请注意，“©”或“版权”后面可能没有年份，而是已经有公司名称。

示例:

ISO 9001:2008, ISO/ IEC 27001:2005 © Mobikasa 2019

考虑到年份可能位于“版权”或“©”一词之前(我认为条件 1 也满足这一点)

示例:

© 2019 Copyright arcadia.io.
2018 © Power Tools LLC

如果有一个 |匹配直到那里并忽略之后的其余部分:

示例:

Copyright 2019 ComputerEase Construction Software | 1-800-544-2530

Answer 1

您可以使用

(?i)(?:©(?:\s*(?:\d{4}(?:\s*[-—–]\s*\d{4})?)?\s*Copyright)?|Copyright(?:\s*(?:\d{4}(?:\s*[-—–]\s*\d{4})?)?\s*©)?)(?:\s*\d{4}(?:\s*[-—–]\s*\d{4})?)?\s*(.*?(?=\s*[.|]|\W*All\s+rights\s+reserved)|.*\b)
