Introduction to XTemplate

XTemplate::XMLTemplate is a class for a XML template. This class has a method expand() and expand2() for expanding a given Hash data. Here is an example.

require 'xtemplate'
# prepare an expansion data.
data = {'members' => [
  {'member' => {'name' => 'name1', 'age' => 27}},
  {'member' => {'name' => 'name2', 'age' => 26}},
]}
# create a template object.
tpl = XTemplate::XMLTemplate.new(<<EOS)
<html><body>
  <ul>
    <li id="/members/member/name" />
  </ul>
</body></html>
EOS
puts(tpl.expand(data))

The result of the above is as follows:

<html><body>
  <ul>
    <li>name1</li><li>name2</li>
  </ul>
</body></html>

In the above section, I show you how to write a ruby script for expanding a template using an expansion data. XTemplate has xtemplate command, which is installed when you installed a set of libraries.
