Overview of XML

As the popularity of XML grew, web developers wanted to use the technology on both the server and client side, but only the former initially offered XML functionality. Starting with Internet Explorer 5.0 and Mozilla 1.0 (predecessor to Firefox), Microsoft and Mozilla implemented JavaScript support for XML in their browsers.

The name of the game in XML is data storage, and that’s what XML excels at.XML got to be so popular because it’s a text-based way of storing your data, and the Internet is based on text transfer. So XML became the Internet’s way of slinging data around, as you already know now that you’re an Ajax developer.

To start create an XML document, you need an XML declaration depends on which version of XML you’re using. Currently, only two versions are possible: version 1.0, the most common, and version 1.1.

every an XML document must begin with XML declaration and Each XML document starts with a start tag and ends with an end tag.

Using Cursor in CSS

An important part of the user interface is the cursor (referred to in the CSS specification as the "pointing device"), which is controlled by a device such as a mouse, trackpad, graphic tablet, or even an optical-reading system. The cursor is useful for providing interaction feedback in most web browsers.

CSS2 lets you change the cursor icon, which means that it's much easier to create web-based applications that function in a manner similar to desktop applications in the operating system.

Cursor property
Values : [[,]* [ auto | default | pointer | crosshair | move | e-resize | ne- resize | nw-resize | n-resize | se-resize | sw-resize | s-resize | w-resize| text | wait | help | progress ]] | inherit
