What Is XML and Why Is It So Important?

Leave a comment

With so many languages in the programming world, it can be confusing to keep track of the purpose of each language.  Lucky for you, today we are tackling exactly: What is XML and why you should care about it.

XML in full stands for “Extensible Markup Language”. This format was introduced in the 1990s and was encrypted in 1998 as a member of the W3C. It serves to transport information. Further, this format is independent as it uses it own tags. What is remarkable is that that web developers are free to choose the language they may wish to include in their web pages. Hence, XML is technically a “markup” language.


To break things further down, a markup language refers to a platform used by individuals to underline documents. By nature, it is easy for students and authors to edit their scholarly work. XML is available for Microsoft Word and Adobe platforms. At the moment, XML has been accepted by many entities from mobile phones to companies. It can be used in an online and offline state.

In more simpler terms, XML is defined as a set of laws that are used in encoding documents in a design that can be read by both machines and human beings. This format has often been applied as a default program by many web developers. For example, Microsoft Word, Open Document, and Apple iWork use this software as a default program for open word documents.

Not surprisingly, the use of XML has taken root globally.

Key features of XML

A good XML document has the following features:

• It is simple. This means that data incorporated in an XML document is readable by the client. This information should be processed by computers swiftly. What is the purpose of using XML if it cannot be read easily?

• It is open. Openness entails the availability of this product on the internet. Members of the W3C have the first priority of accessing XML once it has been released. Non-W3C members can also access the same. This shows the availability of XML to everyone.

• It can read machine related content. Machines can read XML data and even further interpret it. The same applies to human beings.

• It is extensible. Here, web developers can generate their own Document Type Definitions (DTDs). A DTD is a set of rules that is used to authenticate documents. This is therefore a guide used by XML tools to verify information that is required. DTDs allow authors to select referencing styles that are accepted only by XML.

Why is XML Important?

XML enhances independence. Web developers are not limited to any rules. As such, they can create their own tags at their own peril.

XML is vast and efficient. Web designers can now develop tags that match the needs of their audience. Also, at the moment, it is easy for individuals to share data between two computers saving time as a result. They can also recycle information used for other purposes.


XML is flexible. It does not compel web developers to stick to existing rules but rather they can incorporate some rules in areas such as referencing and citation.

XML converts data swiftly and efficiently. Individuals can use XML to HTML documents. The process is quick and information obtained is intact. What’s more is that people can use XML to showcase tiny and large information readable.

XML has been used to generate brand new internet words. An example is the XHTML and the WML. The latter has often been installed in mobile devices.

Initially XML was meant to assist web designers. However this has changed with time. XML now serves quite a large audience that includes; companies, scientists, authors, publicists, desktop publishers among others. Authors can publish as many languages as they wish since the format will edit errors and unwanted mistakes.

XML is the best online platform any individual should strive to use! Since this mechanism has been subscribed to W3C, it means that it has attained international standards. This is a guarantee that the product is of high quality and efficient.

Understanding the different aspects surrounding XML can prove to be very essential, if not outright beneficial for a web designer.
