如何在ruby中使用gsub regex [英] How to use gsub regex in ruby

问题描述

我想从红宝石正则表达式中删除字符串的一部分:

I want to remove some part of string from using ruby regex:

value =本地主机:8393/foobar/1测试:foobartest 我想从字符串[localhost:8393/foobar/1 test:foobartest]和其余的值中删除"test"，以便输出看起来像这样:

value = localhost:8393/foobar/1 test:foobartest I want to remove "test" from my string [localhost:8393/foobar/1 test:foobartest] and rest of the value so that output should look like:

localhost:8393/foobar/1

如何在红宝石中执行此操作?您可以共享一些示例代码来实现这一目标吗?

Appreciated your help in advance! Thanks!

推荐答案

我会做这样的事情:

value = 'localhost:8393/foobar/1 test:foobartest'

value.split.first
#=> "localhost:8393/foobar/1"

或者如果您想使用正则表达式:

Or if you want to use an regexp:

value.sub(/ test.*/, '')
"localhost:8393/foobar/1"
