Question

I am trying to strip all the <br>‘s in a given string.

 def extract(a)
    a=a.delete("/ (\<br\>)+ /")
    puts a
    end

    extract("e<gr>y<br>t<gh>hello")

is giving egytghhello as output. Why is the <r> of <gr> and <> of gh not getting printed?

Answer 1

This should account for <br>, <br /> and <br/> just in case.

str = "Hi and <gr>y<br>t<gh>hello<br />bla<br/> some moar"
puts str.gsub(/<br ?\/?>/,'')

Or using a method like your example:

def extract(str)
   str.gsub(/<br ?\/?>/,'')
end
puts extract("Hi and <gr>y<br>t<gh>hello<br />bla<br/> some moar")

Personally I think is better to have the method return a string and then do puts extract() than having the puts inside the method.
