Tutorial actionscript 3 – Load and read XML file, loading and reading
Reading a forum actionscript http://www.forosdelweb.com/f16/. I found repeated a post asking how to load XML. That motivates me to write the next post.
For those who know nothing about XML stands for Extensible Markup Language, to explain in a simple manner that most are not text files that follow certain standardizations to store data. The syntax rules we impose on xml, allows us to read these files from any language. I am not a scholar on the basic theory of the xml, just give them a good use in my programs. For those who want to study a bit more on xml can be read here. XML IN WIKIPEDIA
XML EXAMPLE:
As you can see the format is quite clever, using a format tag enclosing symbols between greater and less in the identifiers and values, who know html sure you get to fly.
Here a example of the usage. I will continue working on this example to see how to create a gallery of images with this xml.

Where is statusField?
