使用正则表达式从字符串模式中检索数字 [英] Retrieve number from the string pattern using regular expression

问题描述

我有一个字符串Search result:16143 Results found"，我需要从中检索16143.

I have a string "Search result:16143 Results found", and I need to retrieve 16143 out of it.

我正在用 ruby​​ 编码，我知道使用 RegEx 来获得它会很干净(反对基于分隔符拆分字符串)

I am coding in ruby and I know this would be clean to get it using RegEx (as oppose to splitting string based on delimiters)

如何在 ruby​​ 中从这个字符串中检索数字?

How would I retrieve the number from this string in ruby?

推荐答案

我不确定 Ruby 中的语法，但正则表达式将是 "(\d+)" 表示大小为 1 或更大的数字字符串.您可以在这里尝试:http://www.rubular.com/

I'm not sure on the syntax in Ruby, but the regular expression would be "(\d+)" meaning a string of digits of size 1 or more. You can try it out here: http://www.rubular.com/

更新:我相信语法是/(\d+)/.match(your_string)

Updated: I believe the syntax is /(\d+)/.match(your_string)
