Rails - May 2007 - conditional value in xml node

in my rxml file , I wrote :

      xml.Person(:id => "u-"+@user.id.to_s, :name =>
@user.pseudo,
:email => @user.email_address,
      :full_name => full_name, :hops => "0", :imageURL =>
"#{photo_path(@user)}")

but when the full_name is empty I have a value  full_name="" in the
generated file which lead my ActionScript to display a label Name and no
value

I can modify my As , but is there any possibility to writing differently
my xml.Person ?

thanks

kad
