Ruby script where xml contains the above XML text.

  require 'ostruct'

  customer = OpenStruct.new
  customer.name = "John Roberts"
  customer.address = "555 Hobart St"
  customer.city = "Palm Bay"
  customer.state = "FL"
  customer.zip = "32709"
  customer.age = 65
  customer.tags = [ 'ruby', 'javascript' ]

  customer_class = customer.age > 60 ? 'senior' : 'normal'

  rxml = RagTag.compile(xml, binding)

  puts rxml

The script outputs the following.

  <html>
  <body>
    <div class="senior">
      <h1>John Roberts</h1>
      <p>The customer is 65 year old.</p>
