Chapter 9. XML Requests and Responses: More Than Words Can Say
How will you describe yourself in 10 years? How about 20?
Sometimes you need data that can change with your needs... or the needs of your customers. Data you’re using now might need to change in a few hours, or a few days, or a few months. With XML, the extensible markup language, your data can describe itself. That means your scripts won’t be filled with ifs, elses, and switches. Instead, you can use the descriptions that XML provides about itself to figure out how to use the data the XML contains. The result: more flexibility and easier data handling.
Note
As a special bonus, we’re bringing back the DOM in this chapter... keep an eye out!
