You have a broken utf-8 docoment (a read the Matz reply)

I see two solutions:

a)

require 'rexml/document'
require 'iconv'

data =  your xml document
data = Iconv.conv("UTF-8","ISO-8859-1",data)
doc = REXML::Document.new(data)

you must convert the data of doc from utf-8 to iso befor use it

username = Iconv.conv("ISO-8859-1","UTF-8",doc. )

b) change the encoding of the xml

require 'rexml/document'

data =  your xml document
data = data.gsub(/encoding="utf-8"/i, 'encoding="iso-8859-1"')
doc = REXML::Document.new(data)

Anyway a) and b) don't work if the document contains valid utf-8 chars 
not in ascii-7 (for example latin letters 竪, 嘆, etc.)
