I wanted to access the ISBN database, and was previously
parsing the HTML string generated from their main page, that
is until I discovered they have an API that returns XML.
So, if anyone wants to get some information from the ISBN
database, all you need to do is the following.
<?php
//Search the ISBN database for the book.
$url = "http://www.isbnd
b.com/api/books.xml?
access_key=KEY&index1=isbn&value1=$_GET[ISBN]";
$p = xml_parser_create();
xml_parse_into_struct($p,file_get_contents($url),$results
,$index);
xml_parser_free($p);
$title = $results[$index[TITLELONG][0]][value];
$author = $results[$index[AUTHORSTEXT][0]][value];
$publisher = $results[$index[PUBLISHERTEXT][0]][value];
?>
You will need to get an access key from isbndb.com, but it
takes two seconds and is free. When you get it, replace KEY
in the URL with your own key. Also, my code above will
search for the book that fits the ISBN number stored in the
GET variable ISBN - you can search by other parameters and
return more than one result, but my example is for a simple
ISBN search.
