一段时间以来,我一直在尝试寻找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)|[^.]*(?=\.)|.*)

但是当我尝试更多示例时,我发现这还不够。我想更改它,使其也符合以下条件,同时仍然适用于所有以前的情况:

  1. 请考虑在“©”或“版权”(以最后出现的为准)之前可能出现其他任何内容并忽略它。

例子:

602-226-2389 ©2019 Endurance International Group.
Copyright 1999 — 2019 © Iflexion. All rights reserved.
  1. 请注意,在“©”或“版权”之后可能没有年份,但已经有公司名称。

例子:

ISO 9001:2008, ISO/ IEC 27001:2005 © Mobikasa 2019
  1. 考虑到年份可能出现在“版权”或“©”一词之前(我认为条件 1 也满足这一点)

例子:

© 2019 Copyright arcadia.io.
2018 © Power Tools LLC
  1. 如果有|匹配到那里,然后忽略其余部分:

例子:

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

最佳答案

你可以使用

(?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)
