Subject: Re: gsub and multiple-replacement

And here is a xml parsing solution:

require 'rexml/document'
include REXML

xml =<<ENDOFXML
#your xml here
ENDOFXML

replacements = {
  '{username}' => 'BOB',
  '{password}' => 'BOB-PASSWORD',
  '{userroot}' => 'BOB-USERROOT'
}

pattern = '{.*?}'
doc = REXML::Document.new(xml)

XPath.each(doc, '//string') do |element|
  text = element.text
  element.text = text.gsub(/#{pattern}/, replacements)
end

puts doc.to_s


Note that you are using an unfortunate character in the string:

   domain\{userroot}

A backslash has a special meaning in ruby strings.  You need to change 
that to a forward slash(or escape it).
