Removing a character from string in Rspec

Question

I am new to Rspec and I am facing a little issue.

text = page.find(:xpath,"some xpath").text

the code line above gets the value from a html element ie 15% or any other value under 100, I want to remove % sign from the value after and getting it to use for comparison. Can anybody help on this?

Answer 1

您可以使用String#sub替换它：

'15%'.sub('%', '') #=> '15'

Answer 2

如果出现多个事件，也可以使用gsub：

'15%%%'.gsub('%', '') #=> '15'
