how to do the following in ruby ?

Question

I need to grab a string like

"/html/body/a"

i need to check the last portion, in this case "a" after the final "/"

how can i do this ? how can i regex match for the last item after the final "/" ?

Answer 1

x = "/html/body/a"
x.split("/").last  # => "a"

Answer 2

Regex? Not sure, but what's wrong with

my_string.split("/").last # Maybe you want some error checking here, I don't know.

Answer 3

If you want to use regexp, this would be it:

mystring = "/html/body/a"
if mystring =~ /([^\/]+)$/
    last_part = $1
end
