Question

此问题：Regex to match company names from copyright statements under several conditions

我得到了正则表达式：

HTTPOb := CoWinHttpRequest.Create; 
HTTPOb.SetTimeouts(RESOLVETIMEOUT,CONNECTTIMEOUT,SENDTIMEOUT,RECEIVETIMEOUT);

URL := sServer;
HTTPOb.Open(bStrMethod, URL, false);
HTTPOb.SetRequestHeader('MAXM_HOST_OS_NAME', OSName);
HTTPOb.SetRequestHeader('MAXM_HOST_OS_VER', OSVersion);
HTTPOb.SetRequestHeader('MAXM_HOST_APP_NAME', ProductName);
HTTPOb.SetRequestHeader('MAXM_HOST_APP_VER', ProductVersion);

HTTPOb.Send(xml);

但是当我尝试更多示例时，我发现这还不够。我想对其进行更改，使其也符合以下条件，同时仍适用于所有先前的情况：

请注意，在“©”或“版权”（以最后一个为准）之前，可能还有其他内容而忽略了它。

示例：

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

请注意，“©”或“版权”之后可能没有年份，但公司名称已经存在。

示例：

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

考虑到年份可能在“版权”或“©”之前（我认为条件1也可以满足这一要求）

示例：

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

如果有|匹配到那里，然后忽略其余部分：

示例：

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

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)

Answer 2

我相信this regex会为您提供所需的东西。这是解释：

(?i)                                # make the regex case insensitive
(?:Copyright\s*©?|©\s*(Copyright)?) # Look for Copyright and/or © to get us started
([\d\s—-]+)?                        # There might be some digits, spaces, and dashes, but not necessarily
(©|Copyright)?\s*                   # Copyright or © could be separated by dates, so look for them again
(.+?)                               # This is the sugar we're looking for
(?=All rights reserved|\||$)        # If you find "All rights reserved" a | or end of string, stop capturing the text

我知道它的老问题，但想发布更好的解决方案。我训练了spacy模型，该模型对5k +版权文本样本进行了训练。这是模型和作品Repo Link
