In a recent project, it was found that the previous regular matching modules had a very bad performance penalty for long string matching, so the various regular matches under the long string were slightly studied and attached with examples. This article refers to the blog http://www.cnblogs.com/pmars/archive/2012/10/24/2736831.html (hereinafter referred to as Article 1), this article also compares three kinds of regex libraries, But there are some pla

Next, call a new round of contains (), and then use getmatch () to return a new round of results. 2. Understanding of a concept: Group The so-called group is the group used in patte

Differences: 1. The content recognized by contains () can be the part of the input content. However, matchs () must pass the entire input content according to pattern. For example: Input content: 3231 432432 432424 RegEx pattern: \ B \ D + \ B Use matchs (): no match Use contains (): Contain 1: 3231Contain 2: 432432Contain 3: 432424 Enter 432432 Use matchs (): Match Use contains (): Match Difference 2: The instance that is also passed in
