如何匹配正则表达式中的多个单词 [英] How to match multiple words in regex

问题描述

只是一个简单的正则表达式我不知道如何写。

Just a simple regex I don't know how to write.

正则表达式必须确保字符串匹配所有3个单词。我知道如何使它匹配任何 3：

The regex has to make sure a string matches all 3 words. I see how to make it match any of the 3:

/advancedbrain|com_ixxocart|p\=completed/

但我需要确保所有 3字字符串中存在。

but I need to make sure that all 3 words are present in the string.

以下是单词

1. advancebrain


2. com_ixxocart


3. p =已完成

推荐答案

使用前瞻性断言：

^(?=.*advancebrain)(?=.*com_ixxochart)(?=.*p=completed)

如果所有三个条款都存在，

将匹配。

will match if all three terms are present.

您可能想要添加 \b 围绕搜索字词的工作边界，以确保它们匹配为完整的字词，而不是其他字词的子字符串（例如 advancebraindeath ）如果你需要避免这种情况：

You might want to add \b work boundaries around your search terms to ensure that they are matched as complete words and not substrings of other words (like advancebraindeath) if you need to avoid this:

^(?=.*\badvancebrain\b)(?=.*\bcom_ixxochart\b)(?=.*\bp=completed\b)
