XML: Basic principles to get started in programming

Welcome to another article from NelkoDev, your go-to site to learn about programming and marketing. On this occasion, we are going to delve into the basic principles of XML, a markup language widely used in the development of web applications. If you are new to the world of programming, this article is perfect for you as it will provide you with the fundamental knowledge to understand and work with XML.

What is XML?

XML, short for eXtensible Markup Language, is a markup language used to structure and organize data in the form of text that is readable by both machines and humans. Unlike HTML, which is designed to display content visually in a web browser, XML focuses on describing data and transferring it between different systems.

XML uses tags to define elements, attributes to provide additional information, and structuring rules to organize data hierarchically. Thanks to its flexibility and extensibility, XML has become a standard for exchanging information between different platforms and applications.

Main characteristics of XML

Next, we will mention some of the most notable characteristics of XML:

• Readability: XML uses well-defined tags and structures that facilitate human understanding of the content.
• Platform independence: XML can be used on any operating system and platform, making it highly compatible.
• Extensibility: XML allows you to define custom tags to describe any type of data.
• Data separation and presentation: XML focuses on data structuring and not on its visual presentation, which makes it easy to adapt to different environments and devices.

Utilities of XML in programming

XML is used in a wide variety of applications in the programming field. Some of the most common uses are:

• Data exchange: XML allows the exchange of information between different systems, regardless of the platform on which they are located.
• Application Settings: XML is used to define the configuration of various applications, which makes it easy to customize and adapt to the needs of each user.
• Data storage: XML can be used as a storage format to store and retrieve structured data.
• Web services: XML is widely used in developing web services for exchanging data between applications.

Conclusion

In short, XML is a markup language used to describe and structure data in a way that is readable by both humans and machines. Its flexibility and extensibility have made it a fundamental tool in the exchange of information between different systems and applications. We hope this article has given you the basics needed to get started working with XML.
