uninitialized constant Tilt::CompileSite::Nokogiri error in sinatra/haml

Question

I have a two line script that works nicely in ruby. I moved it to haml and getting the error

NameError at / uninitialized constant Tilt::CompileSite::Nokogiri

the haml code:

      %td
        - @doc = Nokogiri::XML(File.open(file))
        = @doc.xpath("//testsuite").each_with_index {|node,index| "#{index+1}. #{node.attributes["name"].value}<BR>" }

any idea how I can make it work?

using below on Win XP SP3

• ruby 1.8.7 (2010-08-16 patchlevel 302) [i386-mingw32]
• nokogiri (1.4.3.1 x86-mingw32)
• sinatra (1.0)
• thin (1.2.7 x86-mswin32)

Answer 1

still do not know why the error happens but I solved it by have a function defined in sinatra file and calling it in haml file = get_testsuite(file)

def get_testsuite (file)

  @doc = Nokogiri::XML(File.open(file))
  output = Array.new
  @doc.xpath("//testsuite").each_with_index {|node,index|
    output << "#{index+1}. #{node.attributes["name"].value}<BR>"
  }
  return output
end

Answer 2

Try this:

%td
  - @doc = ::Nokogiri::XML(File.open(file))
  = @doc.xpath("//testsuite").each_with_index {|node,index| "#{index+1}. #{node.attributes["name"].value}<BR>" }
