The Power of the XMLHTTP Library
(Page 1 of 5 )
XMLHTTP is a set of API's that allows us to send and retrieve data to and from a remote web server using its underlying HTTP protocols and methods. In this article, Mitchell provides us with a basic introduction to the XMLHTTP library, with some examples to get you started.XML, or Extensible Markup Language, is everywhere. Web services, web pages, COM components, database objects, and even the “next generation” of initialization files. XMLHTTP, however, isn’t. XMLHTTP is a set of API’s that allows us to send and retrieve data from and to a remote web server using its underlying HTTP protocols and methods.
The XMLHTTP Application Programming Interface is exposed through Microsoft’s XML library, MSXML. This is an extremely popular library for ASP, VB and C++ developers, and can be downloaded from
http://msdn.microsoft.com/library/default.asp?url=/downloads/list/xmlgeneral.asp. At the time of writing, the current version of MSXML was 4.0.
To get the most out of this article, you should have access to a web server running IIS4/5 on Windows NT/2000. You should also download and install the latest version of the MSXML library, as mentioned above.
This article kick starts our focus on XML over the coming months. You can expect to see dozens of other XML-related articles popping up all over devArticles.com. Anyhow, enough of the chit-chat, lets learn more about XMLHTTP and some of its important functions.
