XML is the short form of Extensible Markup Language which is an entirely text-based markup language that is extracted from Standard Generalized Markup Language. 

As storage for self-descriptive data it was first published on February 10, 1998, and it became a W3C recommendation.

The tags in it are to be defined and it is platform independent. In short, this language uses a set of rules to encode documents in such a format that is readable by both machines and humans.

 The USP of this language is that communication between two platforms that are difficult becomes easy with the use of XML.

Moreover, it is very powerful because of its international acceptance, especially for databases, office applications mobile phones, programming, etc.

Many corporations have incorporated the XML interface because of its platform-independent feature.

The main function of the XML tag is to identify the data and use it to store and organize the data. Some of its important features that you should know are:

1. It is extensible

It will allow you to create a self-descriptive language that will suit your application.

2. It conceals data

The focus of XML is to carry the data and also store it irrespective of its presentation style.

3. It is a public standard

It is completely available as an open standard.

  • XML is not compact. You cannot compress XML as no structure or format is available for such purposes. For XML parsers, the uncompressed text is essential. 

Do not incorporate binary data in XML as it does not support it because of its unsuitability for embedded markup. XML is only appropriate for text data with a hierarchical structure.


You can use the following tips to use XML commands efficiently.

  • The XML file is in a particular place where you need to identify all the elements and write them in the same format across all such files.

  • Always clarify the definition of elements and syntax.
