ruby - How do I return a value from inside a loop? -

i trying read xml file , store structure array of objects. here code:

class bike     attr_accessor :id, :color, :name     def initialize(id, color, name)         @id = id         @color = color         @name = name     end end  ---x---snip---x---  rules.root.each_element |node1|     case node1.name     when "bike"         bike = bike.new(node1.attributes['id'], node1.attributes['color'], { |bike_elem| bike_elem.text.chomp if bike_elem.name == "name"})         bikes.push bike     end end 

however, last element not fetching value alone. fetching whole tag. there better way it?

your code block { |bike_elem| bike_elem.text.chomp if bike_elem.name == "name" } doesn't seem make sense inside new parameter list.

where bike_elem come from? not valid ruby in context.

it's hard give answer here without knowing xml looks like. recommend using xml library nokogiri, libxml, , parse out name before new. try using xpath.

 rules.root.each_element |node1|   case node1.name     when "bike"       name = node1.attributes[....]       bike = bike.new(node1.attributes['id'], node1.attributes['color'],name )       bikes.push bike     end  end
