how to do the following in ruby ?

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 "/" ?

From stackoverflow

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

• Regex? Not sure, but what's wrong with

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

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

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