What Is XML | Introduction

What is XML?

XML (XML) means e X tensive M arkup L anguage. It's a markup language like HTML, but it's different. Like HTML here, there are elements, attributes that are used to create an XML document. However, you can specify elements in HTML (such as body, h1, p, etc.) and create your own custom elements in XML (xml). One of the major differences with XML with HTML is that it is not possible to specify what data is contained within an element with the attribute in XML. Moreover, HTML is created for display in the browser and XML is basically created to hold data and exchange this data with other systems .

Why Learn XML?

A lot of work is done with XML in the web world. Some are described below

==> Suppose you want to highlight the titles of a famous online magazine on your site. The title of that famous magazine is in their database and from there they show on their site, you cannot access their database and fetch their data. In the event that the site's news / headline has an XML format, you can take the data from that XML and display the titles on your site. rss, atom have you heard their names? These are the XML format data of a site.

==> Database works with XML. Joomla and other applications also hold data using XML. This data can be picked up and displayed anywhere in the application. For example, in Joomla, the extension options that can be changed from the backend are all in the XML file.

==> Any system / application can currently read / recognize XML, so XML is currently a language for applications / systems in the web world.

There are many other tasks with XML. If you learn XML, you can display different data from other sites on your site, and if you want to give any data of your site to someone else, then you can create an XML format of those data and put it in the address so that others can use your site data.
