you need to put a backslash right before it. In regexes, \ acts as an escape character that cancels the special meaning of the following character and turns it into a literal character. So, to find a bracket, you prefix it with a backslash: \[ to match an opening bracket and \] to ...
using System; using System.Text.RegularExpressions; public class Example { public static void Main() { string input = "plum-pear"; string pattern = "(-)"; string[] substrings = Regex.Split(input, pattern); // Split on hyphens foreach (string match in substrings) { Console.WriteLine("...
If you want to determine whether one or more strings match a regular expression pattern and then retrieve them for subsequent manipulation, call the Match or Matches method. The static IsMatch(String, String, RegexOptions, TimeSpan) method is equivalent to constructing a Regex object with the ...
import re text = "This is a sample text with spaces and empty strings." pattern = r'\S+' result = re.findall(pattern, text) print(result) 输出结果将是: 代码语言:txt 复制 ['This', 'is', 'a', 'sample', 'text', 'with', 'spaces', 'and', 'empty', 'strings.'] 这个结果忽略...
代码点 输入 中匹配 的索引(而不是字节索引),以及string 与匹配字符串所捕获群组对应的字符串数组。捕获群组在 regex 模式中用未转义括号 () 指定。 [ { "match" : <string>, "idx" : <num>, "captures" : <array of strings> }, ... ] 另请参阅: $regexFind $regexMatch ...

REGEX is a powerful and flexible way to search for and match patterns in text strings. You can use REGEX to perform various tasks, such as: Extracting specific information from a text string, such as names, dates, numbers, etc. Replacing parts of a text string with another text string, ...

(for example, letters between A and Z) and special characters (called "metacharacters"). It is a computer science concept. Regular expressions use a single string to describe and match a series of strings that match a syntactic rule. They are often used to retrieve and replace text that ...
