Are you looking for something like this?

irb(main):011:0> require 'rexml/document'
=> true
irb(main):012:0> docs = (1..5).map do |i|
irb(main):013:1* d = REXML::Document.new
irb(main):014:1> d.add_element("my_root").text = "item no. #{i}"
irb(main):015:1> d.to_s
irb(main):016:1> end
=> ["<my_root>item no. 1</my_root>", "<my_root>item no. 2</my_root>",
"<my_root>item no. 3</my_root>", "<my_root>item no. 4</my_root>",
"<my_root>item no. 5</my_root>"]
irb(main):017:0> docs[2]
=> "<my_root>item no. 3</my_root>"
irb(main):018:0>

Of course your document construction is likely more complex.
