What is XML and its Functions You Need to Know

What is XML?

XML is a markup language that can be created by the world wide web consortium. This extensible markup language is a language that can be used to simplify the process of storing and sending data between servers.

Storage and transmission of data between servers need to be simplified because each server has a different system. This makes data exchange between servers not necessarily compatible with each other and can take a lot of time. 

For that, you need XML to store data in a very simple text format. You no longer need to change the data format at all. Even the data format will remain the same even if transferred to another server. 

XML is very easy to update to a new OS form or browser. The language is also very easy to understand by humans, PCs and other speech recognition technologies. Technology will certainly make it easier for you. XML has a number of advantages.

The advantages of XML include: 

  1. XML is able to make documents can be transported across certain systems and applications, of course, practically and very easily. 
  2. XML can also be used to quickly exchange data between a wide variety of platforms. This benefit is most often felt by XML users.  
  3. XML can be used to separate data from HTML. This way, you don't have to bother separating them manually anymore. 
  4. XML can be used to simplify the process of changing a particular platform.

Difference between XML and HTML

Difference between XML and HTML

XML is a markup language used to store and transmit data. Meanwhile, HTML is a data viewer. 

So, the two are clearly different even though at first glance they look similar. In addition, XML can also use any tags and this does not apply to HTML. 

HTML requires special tags and predefined tags to function properly.

In addition, there are other parameters that are used to measure the difference between XML and HTML, such as the following. 

  1. XML stands for eXtensible Markup Language. Meanwhile, HTML stands for Hypertext Markup Language. 
  2. XML has a focus on data transfer. In contrast to HTML which only focuses on presenting data. 
  3. XML is always content driven whereas HTML is case intensive. 
  4. XML provides name space support while HTML does not. 
  5. XML tags cannot be predefined whereas HTML is predefined. 
  6. XML tags are extensible whereas HTML has limited tags. 
  7. XML is strict for the closing section tag while HTML is not strict.
