This page is an example of using the Amazon.com web services API (XML over HTTP) to get information about a book to add it to my Book Recommendations Page. To try it, type in an ISBN in the form. (There is a valid ISBN in the form by-default.)

This page works as follows:

• The page is an HTML form.
• Submitting the form activates a PHP Script.
• The PHP script parses the form input and execs a Java process that makes the request from amazon and returns an XML response containing the an the URL of the image file for the book cover and a snippet of XML that I can use to add an entry to the book recommedations page.
• The PHP script parses the XML, checks for error messages, and creates the final page.

Note that there are a few other ways to do this:

• Entirely in PHP.
• Using the Amazon.com SOAP API.
