REST in rails 1.2.5

Hi      I am using rails 1.2.5 And as part of learning rails I just create a model Person and migrated it (I am following the REST for rails 2 tutorial from peepcode) Then did ./script/generate scaffold Person

     Now inside config/routes.rb added map.resources :people   In people controller index action def index     @person_pages, @people = paginate :people, :per_page => 10     respond_to do |format|        format.html        format.xml { render :xml => @people }     end end      And also have the view file Now when http://localhost:3000/people I get the data displayed But when http://localhost:3000/people.xml I get

XML Parsing Error: unclosed token Location: http://localhost:3000/people.xml Line Number 1, Column 1:

              could you please tell why this error happens?Also is there huge differnece in REST for rails 1.2.5 and 2.x

Thanks in advance Sijo
