Markup code, or markup language, is actually a couple of words and symbols developed by the computer industry with the purpose of assisting to process, organize, and present information, in addition to to see the computer on how best to interpret a document.

Instead of other programming languages, markup languages are both user-friendly and machine-friendly. Generally, they include standard words in a syntactical way which allows them to be easily understood by the reader. Although a variety of markup languages exist, HTML and XML are two of the very most popular markup languages.

Recently, HTML and XML have grown to be two of the most famous languages used over the internet. Because of their wide variety of applications, advantages, and disadvantages, these languages may be used in a number of different scenarios. Here, we shall compare two of the very most markup languages in a variety of aspects.

Lets have a look at data science scenario-based interview questions.

What’s XML?

The Extensible Markup Language (XML), also called the XML Schema, is really a markup language for describing, formatting, transmitting, and reconstructing arbitrary data in a number of formats. It outlines the guidelines for encoding documents in a manner that makes them both machine-readable and human-readable. When it comes to its dynamic nature, it serves as a way of transporting data, not for displaying it.

XML emphasizes simplicity, generality, in addition to a amount of flexibility to use over the Internet. As the XML is devoted to documents, the language could also be used to represent any arbitrary data structure, including those useful for web services. Users have the freedom to create their very own tags in XML they’re self-descriptive.

Top features of XML

  • As XML stores data in plain text format, it simplifies data storage. This makes retrieval easier than in databases.
  • With regards to the transport of data, XML files are excellent, specifically for applications that aren’t appropriate for rendering other data formats.
  • The XML format works with with many reading devices, rendering it accessible to those who find themselves blind or have other disabilities.
  • The XML language is extensible. Users can make self-descriptive tags in virtually any language according to the application requirements.
  • You can find no predefined tags in XML. It is very important define your customized tags.

What’s HMTL?

HyperText Markup Language (HTML) is really a standard language for web-based documents. It includes a group of elements that wrap and enclose content, causing it to behave or come in a specific way.

Utilizing the enclosing tags, it is possible to hyperlink words or images, italicize words, make fonts bigger or smaller, among other abilities. Aided by technologies such as for example Cascading Style Sheets (CSS) and scripting languages like JavaScript, this technique can be easier accomplished. An enclosing tag can hyperlink a word or image to some other, italicize words or make the font bigger or smaller.

It really is used to annotate (note for the computer) text so a machine can better understand it and manipulate the written text. Furthermore, website designers may use HTML to generate ordering forms, reservations, and search forms. The HTML coding language, therefore, may be the cornerstone of creating your brand and running your web subscription-based business.

Top features of HTML

  • Besides being truly a simple, easy language, it supports authoring webpages and is simple to understand.
  • Codes could be modified and so are easily understood by everyone.
  • HTML contains many tags which you can use to create webpages.
  • This tool allows the creation of webpages with this content of the users choice.
  • Moreover, it offers hyperlinks to other pages, making browsing easier.
  • The HTML language is in addition to the operating-system (OS). It really is appropriate for Windows, Mac, and Linux.
  • Pages could be embellished with graphics, sounds and videos, making them very attractive.
  • It really is easily appropriate for scripting and styling languages such as for example CSS and JavaScript, enabling dynamic functionality.
  • There’s enough support to embed multimedia in documents.
  • It really is flexible enough to aid hypertext links if necessary.


Although both HTML and XML are markup languages, they differ significantly in lots of ways. Both have several benefits and disadvantages that may also be studied into account when coming up with decisions. They are probably the most significant differences between your two:

  1. Objective

By its very nature, XML is made for the objective of transporting and storing information.

In comparison, HTML can be used to enhance the looks of text and data.

  1. Tags

Within XML, an individual gets the option of fabricating tags. This enables users to generate tags in virtually any language they really want.

Tags are predefined in HTML. A user may use the tags to generate web pages predicated on their needs.

  1. Nature

Since XML can be used for data transport, it really is dynamic in nature.

Because HTML is primarily used to show data, it really is static in nature.

  1. Language Type

Since XML is case-sensitive, its vital that you keep carefully the upper and lower cases at heart when writing code.

Since HTML isn’t case-sensitive, upper and lower case aren’t important.

  1. Coding Errors

XML will not give the end result when there is one in the code.

Small coding errors could be ignored in HTML and the results can be achieved.

  1. Document size

The document size could be large in XML.

HTML will not support lengthy documents. A best-formatted output may be accomplished simply by adding the syntax.

  1. Eng of tags

A well-formed XML document will need to have a closing tag.

A closing tag isnt always needed in HTML. As the tag should be paired with a tag, the
tag will not need a

  1. Whitespaces

In XML, whitespaces are preserved you might utilize them in your code.

The HTML language will not preserve whitespaces, which means you cannot utilize them in your code.

  1. Nesting

In XML, nesting must be done appropriately.

Nesting will not affect Html page at all.

  1. Drivers

As XML is content-driven, it generally does not have many formatting options.

HTML, however, is presentation-driven. The looks of the written text is really important.

  1. Object Support

XML objects are expressed using conventions, mainly attributes and elements.

The HTML language supports native objects.

  1. Null Support

XML instance documents must use xsi:nil on elements and the corresponding namespace must be imported.

The HTML language recognizes the null value natively.

  1. Formatting Decisions

In XML, mapping application types to XML elements and attributes takes additional time and effort.

Direct mapping is provided for application data in HTML.

  1. Document Size

A document in XML usually includes a large size, particularly when it uses an element-centric method of formatting.

HTML includes a brief syntax and produces formatted text.

  1. Parsing in JavaScript

XML takes a DOM implementation and JavaScript code to map the written text into objects.

To parse text in HTML, you don’t have to create any extra application code. This is often accomplished using JavaScripts eval function.

  1. Learning Curve

It is extremely difficult to understand XML since it entails learning technologies such as for example DOM, XPath, and XML Schema.

Developers are aware of HTML since it is really a simple technology stack.


XML and HTML are both markup languages that cope with data and will be utilized together. They both utilize Standard Generalized Markup Language (SGML) and react to browser requests directly or using AJAX. The Html page is in charge of displaying the info, whereas the XML code is in charge of storing and transferring the info. Despite the fact that both languages are markup languages, their working methods differ greatly.

HTML and XML form the structural foundation of each website or application, so learning them is essential. While HTML is really a simple predefined language, XML is really a standard language used to define other languages. The significance of learning both HTML and XML can’t be overstated, being that they are the foundations of most websites and applications, serving because the structural and integral elements.
