Request
XML Response
Everything in the rst part of the
book sent text to the server using
name/value pairs.
All these earlier apps got text
back from the server, too.
Remember, even with POST
requests in Chapter 5, we
were sending plain text.
Chapter 4 was all about
the DOM... no requests or
responses here.
In Chapter 6, we were still
sending text in our requests.
The server nally got to say
more, though, and sent XML
back in its responses.
A review of request and response formats
Before we dive into the JSON versus XML debate, let’s review the data
formats we’ve already used in the rst six chapters.
XML makes it easy
for the server to
send more complex
responses to your
requests... but your
requests are still
usually better off
as plain text.
