Same Name Selection

[pingpink]

I want to select groups or components , and material faces by the same name for the purpose of swapping objects and colors in a whole set for the revision , but I don't know an appropriate method to do it.
what should I do ?

def select_object_by_name

  model=Sketchup.active_model
  ss=model.selection
  ss.each do |e|
  if e.is_a? Sketchup;;ComponentInstance || e.is_a? Sketchup;;Group
  model.active_entities.each{|e|ss.add e if e.typename == component.definition.name}
  model.active_entities.each{|e|ss.add e if e.typename == group.entities.parent}
  end
  end
end


def select_material_by_name

  model=Sketchup.active_model
  ss=model.selection
  ss.each do |e|
  if e.is_a? Sketchup;;Face
  model.active_entities.each{|e|ss.add e if e.typename == face.material}
  end
  end
end

Some alternative ideas...

def select_active_instances_of_same_definition()
  model=Sketchup.active_model
  ants=model.active_entities
  ss=model.selection
  ss.grep(Sketchup;;ComponentInstance).each{|i|
    defn=i.definition
    ants.grep(Sketchup;;ComponentInstance).find_all{|e|
      e.definition==defn
    }.each{|e|
      ss.add(e)
    }
  }
end#def

def select_active_groups_with_same_name()
  model=Sketchup.active_model
  ants=model.active_entities
  ss=model.selection
  ss.grep(Sketchup;;Group).each{|g|
    next if (n=g.name).empty? ### ??
    ants.grep(Sketchup;;Group).each{|e|
      ss.add(e) if n==e.name
    }
  }
end#def

def select_active_faces_with_same_material()
  model=Sketchup.active_model
  ants=model.active_entities
  ss=model.selection
  ss.grep(Sketchup;;Face).each{|f|
    mat=f.material
    ants.grep(Sketchup;;Face).find_all{|e|
      e.material==mat
    }.each{|e|
      ss.add(e)
    }
    break ### stops after first face in selection is processed
    ### add a leading # to process ALL selected faces
  }
end#def

I'm very grateful for your help , Professor TIG !
I test codes and they works for selecting groups and components with the same name , but the same face material seems doesn't select. I don't know why.
You are so nice !!

      model=Sketchup.active_model
      ants=model.active_entities
      ss=model.selection
      ss.grep(Sketchup;;Face).each{|f|
        mat=f.material
        ants.grep(Sketchup;;Face).find_all{|e|
          e.material==mat
        }.each{|e|
          ss.add(e)
        }
        break ### stops after first face in selection is processed
        ### add a leading # to process ALL selected faces
      }
end#def

Typo !
ss.add
should be
ss.add**(e)**

By the way - on the usage of typename: http://www.thomthom.net/thoughts/2011/12/never-ever-use-typename/

Wow !

Many thanks for the useful tool. I can revise model quickly.
It works very very nice !!
