You want to understand how to read or write XML.
XML is tag-based and hierarchical. If you are familiar with HTML, learning the basics of XML should not be very difficult.
Although reading and writing good XML is not a skill that is specific to ActionScript, it is, nonetheless, a skill from which your ActionScript can benefit. If you are not yet familiar with XML, don’t worry. This is going to be painless.
XML is a way of representing structured data. This means that you explicitly define the context for the data. For example, without XML you might have a string of data such as:
