So, this answer to my previous question supposedly should work as i need, but I'm not sure, how to get strings list from regex matches for particular code: foreach (string phrase in matchWordsList) { foreach (string str in

I can't compile a simple assembly project getting this error: .\Objects\learn.sct(7): error: L6236E: No section matches selector - no section to be FIRST/LAST. I've tried searching and couldn't find any solution for this problem. This is what I do: Create a project ( without the startup file) Add a new assembly file (learn.s) Click Build Target . Can anybody help? 回答1: There is no 'FIRST' object in your source code. Your scatter file likely looks something like: LR_IROM1

How do I count the number of matches by a regex?

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: For example, I would like to count how many numbers are in a string using a regex like: [0-9] 回答1: Regex.Matches(text, pattern).Count 回答2: Regex.Matches(input, @"\d").Count Since this is going to allocate a Match instance for each match, this may be sub-optimal performance-wise. My instinct would be to do something like the following: input.Count(Char.IsDigit) 回答3: var a = new Regex("[0-9]"); Console.WriteLine(a.Matches("1234").Count); Console.ReadKey(); 回答4: The MatchCollection instance returned from a call to the Matches method on RegEx

regex matches with intersection in C#

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I wonder if it is possible to get MatchCollection with all matches even if there's intersection among them. string input = "a a a"; Regex regex = new Regex("a a"); MatchCollection matches = regex.Matches(input); Console.WriteLine(matches.Count); This code returns 1, but I want it to return 2. How to achive it? Thank you for your help. 回答1: string input = "a a a"; Regex regexObj = new Regex("a a"); Match matchObj = regexObj.Match(input); while (matchObj.Success) { matchObj = regexObj.Match(input, matchObj.Index + 1); } will iterate over the

正则表达式在 PHP 中的应用 在 PHP 应用中,正则表达式主要用于: 正则匹配:根据正则表达式匹配相应的内容 正则替换:根据正则表达式匹配内容并替换 正则分割:根据正则表达式分割字符串 在 PHP 中有两类正则表达式函数,一类是 Perl 兼容正则表达式函数,一类是 POSIX 扩展正则表达式函数。二者差别不大,而且推荐使用Perl 兼容正则表达式函数,因此下文都是以 Perl 兼容正则表达式函数为例子说明。 定界符 Perl 兼容模式的正则表达式函数,其正则表达式需要写在定界符中。任何不是字母、数字或反斜线()的字符都可以作为定界符,通常我们使用 / 作为定界符。具体使用见下面的例子。 提示 尽管正则表达式功能非常强大,但如果用普通字符串处理函数能完成的,就尽量不要用正则表达式函数,因为正则表达式效率会低得多。关于普通字符串处理函数,请参见《 PHP 字符串处理 》。 preg_match() preg_match() 函数用于进行正则表达式匹配,成功返回 1 ,否则返回 0 。 语法: int preg_match( string pattern, string subject [, array matches ] ) 参数说明: 参数 说明 pattern 正则表达式 subject 需要匹配检索的对象 matches 可选,存储匹配结果的数组, $matches[0]

一,认识正则 首先看下面的代码 , $str声明一个字符串 , $patt 匹配规则, preg_match_all()函数用于执行一个全局正则表达式匹配。 <?php $str = 'hi,this is his history'; $patt = '/hi/'; preg_match_all($patt,$str,$matches); print_r($matches); 匹配结果 正则,我们平时用的不多,所以容易忘; 所以在记忆时着重点进行记忆,找谁?怎么找?找几个? 二,常用字符簇 三,单词匹配 <?php $str = 'hi,this is history111**+ '; $patt = '/\Bhi\B/'; preg_match_all($patt,$str,$matches); print_r($matches); $str = 'hi,this is history111**+ '; $patt = '/\bhi\b/'; preg_match_all($patt,$str,$matches); print_r($matches); 四,集合与补集 <?php //集合示例代码 $str = ['13800138000','13426060134','170235','18265432185932545']; //寻找包含0123456 同时又是11位的元素

1、下载swagger-ui GitHub地址: https://github.com/swagger-api/swagger-ui 2、把 swagger-ui 目录下的 dist 放到你的 public 目录下,然后更名为 swagger。 3、修改 swagger 下 index.html 的路径: window.onload = function() { // Begin Swagger UI call region const ui = SwaggerUIBundle({ url : window.location.href.replace(window.location.hash, "").replace(/[^/]+$/, "swagger.json"), dom_id: '#swagger-ui', deepLinking: true, presets: [ SwaggerUIBundle.presets.apis, SwaggerUIStandalonePreset ], plugins: [ SwaggerUIBundle.plugins.DownloadUrl ], layout: "StandaloneLayout" }) // End Swagger UI call region window.ui = ui } 4、在 public 下新建 api

Spring AntPathMatcher 实现原理

我们两清 提交于 2019-11-30 01:00:49
最近在看Spring 源码,源码中多次出现AntPatternMatcher 类, 此类作用用于实现对URL的匹配 关于此类的介绍,其中有些代码是从Apache Ant 那 "借"过来的 PathMatcher implementation for Ant-style path patterns. Examples are provided below. Part of this mapping code has been kindly borrowed from Apache Ant . The mapping matches URLs using the following rules: ? matches one character * matches zero or more characters ** matches zero or more 'directories' in a path Some examples: com/t?st.jsp - matches com/test.jsp but also com/tast.jsp or com/txst.jsp com/*.jsp - matches all .jsp files in the com directory com/**/test.jsp - matches all test.jsp files
