On the other hand, XML is a language for data-description and is used to store data. Ability to customize: HTML uses a pre-selected range of markup symbols or shortcodes, which describe the presentation of a web page's content.

Conversely, XML is extensible and allows users to customize and create their own markup symbols. In this way, with XML, users have complete control and can create an unlimited symbol set to describe their content.

Advantages of XML. Readability: For a data analyst, the data must be easily accessible and readable. XML files are easy to comprehend because they use human language with actual words instead of a computer language. For example, XML tag names clearly define and explain the data. Each tag is arranged to come before its data, so the information is neat and organized.

It lets you automatically customize the presentation of data rather than display the same page to all comers. And it makes searches more efficient because search engines can sort through precise tags rather than long pages of text. Because XML brings sophisticated data coding to Web sites, it helps companies integrate their information flows.

By creating a single set of XML tags for all corporate data, information can be shared seamlessly among Web sites, databases, and other back-end systems.

But the revolutionary power of XML lies in supporting transactions between businesses. When a company sells a good or service to another company, a great deal of information needs to be exchanged—about prices, terms, specifications, delivery schedules, and so on. With XML, all the necessary information can be shared electronically, allowing complex deals to be closed without any human intervention. The XML specification itself is approximately 30 pages long, and is aimed at computer programmers and information specialists.

And these programs instruct the computer to perform the defined tasks. However, XML does not qualify to be a programming language as it does not perform any computations or algorithms. It is generally stored in text files and processed by the software design for interpreting XML. Writing XML documents are easy as compared to other markup languages.

There are no predefined rules to follow, and authors can create their own tags and rules to serve their needs. In this way, XML is very flexible in terms of developing the document. It can also be put in the backend of any web application to maintain the style sheets. These style sheets can be updated by updating the XML documents.

Due to its simple nature, it is being used by all leading companies like Xerox, Microsoft, Google, Facebook, Ford Motors, and many others. XML is used for the storage and transportation of data and information. It is purely a document-based technology independent of any specialized software or hardware requirement. It is also a self-descriptive language. Being self-descriptive, it contains sender information, receiver information, a heading, and a message body.

It also simplifies several things like data sharing, data transport, platform changes, and data availability. Moreover, it is a W3C recommendation. It can also have a declaration, as shown below.

Here the XML version and encoding define the character encoding used in the document. A sample declaration is given below:. It allows the nesting of statements, but they should not overlap each other.
