结合两个正则表达式 [英] Combine two regexes

问题描述

我有两个正则表达式，它们在独立使用时运行良好.

I have two regular expressions which are working perfectly fine when use independently.

First  : ^.+\.((jpeg)|(gif)|(png))\s*$ : search for .jpeg,gif or png at the end of url 
Second : ^.+(javax.faces.resource|rfRes).* : search for two url patterns 

我想结合以上两个表达式，使得url以任何图像结尾"或url在其路径中有javax.faces.resource或rfRes"

I want to combine the above two expressions such that " url ends in any of the image " OR "url has javax.faces.resource or rfRes in its path"

我尝试使用 |操作员加入两者，但它似乎不像下面这样工作:

I tried using | operator to join both but it seems its not working like below :

^.+\.((jpeg)|(gif)|(png))\s*$ | ^.+(javax.faces.resource|rfRes).* 

但它不起作用.

有人可以帮忙加入以上两个正则表达式吗?

Can anybody please help in joining above two regex ?

推荐答案

| 运算符周围有额外的空格:

You have extra spaces around the | operator:

Your original regex
^.+\.((jpeg)|(gif)|(png))\s*$ | ^.+(javax.faces.resource|rfRes).*
^.+\.((jpeg)|(gif)|(png))\s*$|^.+(javax.faces.resource|rfRes).*
Fixed regex                  ^
                             |

您的解决方案将尝试匹配字符串的结尾然后是一个空格"或一个空格然后是字符串的开头".请记住，空格在正则表达式中很重要.

Your solution will try to match "the end of the string and then a space," or "a space and then the beginning of the string." Remember, whitespace is significant in regexes.
