正则表达式的字符串 [英] Regex for the string
问题描述
请程序员，当谈到正则表达式时，我不是goot。
拜托，你能提供与这个字符串匹配的正则表达式X | 3.20 | S | 0
我尝试了什么：
还没有，因为我不知道。
尝试：
（。+？\ |）{3} 0可能不会帮助你 - 你需要查看整个负载更多的数据样本...
不清楚你想做什么，但你也可以尝试这个正则表达式
\ b（（X /）？X \ | [0-9] \。[0-9] {2} \ | S \\ \\ | [0-9] {1}）\ b
示例： cp_reg_string在X | 3.20 | S | 0 |之间C＃在线编译器| .NET小提琴 [ ^ ]
< blockquote>这个应该这样做：
\ sX \ | 3 \。20 \ | S\ | 0
只是一些有趣的链接，可帮助构建和调试RegEx。
以下是RegEx文档的链接：
perlre - perldoc.perl.org [ ^ ]
以下是帮助构建RegEx并调试它们的工具的链接：
< a href =http://regexstorm.net/tester> .NET正则表达式测试程序 - 正则表达式风暴 [ ^ ]
Expresso正则表达式工具 [ ^ ]
RegExr：Learn，Build，&测试RegEx [ ^ ]
在线正则表达式测试器和调试器：PHP，PCRE，Python，Golang和JavaScript [ ^ ]
这个显示RegEx是一个很好的图表，它非常有助于理解RegEx的作用：
Debuggex：在线可视正则表达式测试器。 JavaScript，Python和PCRE。 [ ^ ]
这个网站也在一个漂亮的图表中显示正则表达式，但无法测试与RegEx匹配的内容：
Regexper [ ^ ]
please programmers, I am not goot atall when it comes to regex.
please, can you provide the regex that match this string " X|3.20|S|0"
What I have tried:
nothing yet as I don't know it.
Try:
(.+?\|){3}0Probably won't help you though - you need to look at a whole load more data samples...
Not clear what you trying to do, but you also can try this regular expression
\b((X/)?X\|[0-9]\.[0-9]{2}\|S\|[0-9]{1})\b
Example: cp_reg_string between X|3.20|S|0 | C# Online Compiler | .NET Fiddle[^]
This one should do:
\sX\|3\.20\|S\|0
Just a few interesting links to help building and debugging RegEx.
Here is a link to RegEx documentation:
perlre - perldoc.perl.org[^]
Here is links to tools to help build RegEx and debug them:
.NET Regex Tester - Regex Storm[^]
Expresso Regular Expression Tool[^]
RegExr: Learn, Build, & Test RegEx[^]
Online regex tester and debugger: PHP, PCRE, Python, Golang and JavaScript[^]
This one show you the RegEx as a nice graph which is really helpful to understand what is doing a RegEx:
Debuggex: Online visual regex tester. JavaScript, Python, and PCRE.[^]
This site also show the Regex in a nice graph but can't test what match the RegEx:
