newbie to using builder(xml)

Show all headers | View raw

Hi,

I am just trying to understand how builder sorts the content of an xml
node, because no matter how I arrange the options, they appears sorted
differently in the irb.

ids = ["1","2","3"]
alphas = ["xxx","yyy","zzz"]

xml = Builder::XmlMarkup.new( :target => $stdout, :indent => 2 )

xml.instruct! :xml, :version => "1.1", :encoding => "US-ASCII"

ids.each do |num|

  xml.programme(:alpha => alphas.fetch(ids.index(num)), :id => num)

end

This prints:
<programme alpha="xxx" id="1"/>
<programme alpha="yyy" id="2"/>
<programme alpha="zzz" id="3"/>

But if I re-arrange the positioning to:

xml.programme(:id => num, :alpha => alphas.fetch(ids.index(num)))

It still produces:
<programme alpha="xxx" id="1"/>
<programme alpha="yyy" id="2"/>
<programme alpha="zzz" id="3"/>

NO CHANGE!!!

Also, is there an easy way to map the values of the arrays together,
than using the fetch method?

THANKS IN ADVANCE!!
