Ruby on Rails and XML

This tutorial discuss some basics about the way that Rails works, how it's structured and how to use it, and then you'll move on to working with XML. There are a number of ways to both generate and parse XML in Ruby, and you'll look at a few of them, including REXML (Ruby Electric XML), Builder and Hpricot (Technically Hpricot is an HTML parser -- but it's fast, and works on XML, too).

The objectives of this tutorial are as follows:

• Build the skeletal Ruby on Rails app (preparation for XML processing)
• Create a new XML document
• Download the XML document
• Upload a file in Rails (in this case, XML)
• Parse and manipulate XML
