Ruby/Rails使用gsub和数组 [英] Ruby/Rails working with gsub and arrays

问题描述

我有一个在Ruby中使用gsub方法时要使用的字符串.问题是我有一个动态的字符串数组，需要迭代以搜索原始文本并替换为该字符串.

I have a string that I am trying to work with in using the gsub method in Ruby. The problem is that I have a dynamic array of strings that I need to iterate through to search the original text for and replace with.

例如，如果我有以下原始字符串(这是我正在使用的一些示例文本，希望可以正常使用)，并且有一组要搜索和替换的项目.

For example if I have the following original string (This is some sample text that I am working with and will hopefully get it all working) and have an array of items I want to search through and replace.

感谢您的提前帮助！

推荐答案

a = ['This is some sample text',
     'This is some sample text',
     'This is some sample text']

所以a是示例数组，然后遍历该数组并替换值

so a is the example array, and then loop through the array and replace the value

a.each do |s|
    s.gsub!('This is some sample text', 'replacement')
end
