本文介绍了如何使用RegEx匹配'{{{'的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

给定的字符串类似于:

words words {{{value}}} some other words {{{value2}}}

我正在尝试以下操作:

const string pattern = @"\b({{{)\w+(}}})\b";
Regex optionRegex = new Regex(pattern, RegexOptions.Compiled);
MatchCollection matches = optionRegex.Matches(text);

和 @"\ b(\ {\ {\ {)\ w +(\} \} \})\ b" 没有帮助.请帮助创建正则表达式TIA

and @"\b(\{\{\{)\w+(\}\}\})\b" didn't helped. Please, help to create regex, TIA

推荐答案

您的正则表达式应为:

@"{{{\w+}}}"

问题在于，您尝试匹配的位置没有单词边界( \ b ).

The problem is that there is no word boundary (\b) where you were trying to match.

您可以根据需要添加分组，但是您似乎不太可能这样做，因为您知道第一组包含 {{{/code>.也许您打算将单词分组在里面:

You can add the grouping in if you need it, but it seems unlikely that you do since you know that the first group contains {{{ and the second contains }}}. Perhaps you meant to group the word inside:

@"{{{(\w+)}}}"
