Subject: Re: Ordering XML Attributes with Hpricot?

Dear Lance,

I accidentally hit the "send" button too early:

a Hash can be sorted to give an Array with Hash#sort :

You can then iterate through the Array with Array#each_with_index,
eg.

my_array.each_with_index{|x,i| if i%2==0 ; p x + "\n"; else p x; end}

Best regards,
