XML is a markup language which is designed to store data. It is popularly used for the transfer of data. It is case sensitive. XML offers you to define markup elements and generate customized markup language. The basic unit in the XML is known as an element.

What is
HTML?HTML is the markup language which helps you to create and design web content. It has a variety of tag and attributes for defining the layout and structure of the web document. It is designed to display data in a formatted manner. A HTML document has the extension .htm or .html. You can edit HTML code is any basic code editor, even notepad. The edited code can be executed in any browser. Browsers render the tags used and present the content you want to display with
or without applied formatting.
What is the Difference between XML and HTML?The key difference between XML and HTML is that XML is a framework for specifying markup languages (stores and transfers data). In contrast, HTML is a predefined markup language (describes the structure of a webpage). KEY DIFFERENCE- XML is abbreviation for extensible Markup Language whereas HTML stands for
Hypertext Markup Language.
- XML mainly focuses on transfer of data while HTML is focused on presentation of the data.
- XML is content driven whereas HTML is format driven.
- XML is Case sensitive while HTML is Case insensitive.
- XML provides namespaces support while HTML doesn’t provide namespaces support.
- XML is strict for closing tag while HTML is not strict.
- XML tags are extensible whereas HTML has limited tags.
- XML tags are not predefined
whereas HTML has predefined tags.
Features of XML Google Trends HTML vs XML- XML tags are not predefined. You need to
define your customized tags.
- XML was designed to carry data, not to display that data.
- Mark-up code of XML is easy to understand for a human.
- Well structured format is easy to read and write from programs.
- XML is an extensible markup language like HTML.
Features of HTML
Stack Overflow Questions HTML vs XML- It is a simple language which supports the authoring of web pages.
- Rich enough to provide support for multimedia embedding in documents
- Flexible enough to support hypertext linking

Difference between XML and HTML | Parameter | XML | HTML |
|---|
| Type of language
| XML is a framework for specifying markup languages.
| HTML is predefined markup language.
| | Language type
| Case sensitive
| Case insensitive
| | Structural details
| It is provided
| It is not provided.
| | Purpose
| Transfer of data
| Presentation of the data
| | Coding Errors
| No coding errors are allowed.
| Small errors are ignored.
| | Whitespace
| You can use whitespaces in your code.
| You can’t use white spaces in your code.
| | Nesting
| Should be done appropriately.
| Does not have any effect on the code.
| | Driven by
| XML is content driven
| HTML is format driven
| | End of tags
| The closing tag is essential in a well-formed XML document.
| The closing tag is not always
required. <HTML> tag needs an equivalent </HTML> tag but <br> tag does not require </br> tag
| | Quotes
| Quotes required around
XML attribute values?.
| Quotes are not required for the values of attributes.
| | Object support
| Objects have to be expressed by conventions. Mostly using attributes and elements.
| Offers native object support
| | Null support
| Need to use xsi:nil on elements in an XML instance document and also need to import the corresponding namespace.
| Natively recognizes the null value.
| | Namespaces
| XML provides support for namespaces. It helps you to remove the risk of name collisions when combining with other documents.
| Does not support the concept of namespaces. Naming collisions can be avoided either using a prefix in an object member name or by nesting objects.
| | Formatting decisions
| Require more significant effort to map application types to XML elements and attributes.
| Provides direct mapping for application data.
| | Size
| Documents are mostly lengthy in size, especially when an element-centric approach used in formatting.
| The syntax is very brief and yields formatted text.
| | Parsing in Javascript
| Requires an XML DOM implementation and application code to map text back into JavaScript objects.
| No extra application code required to parse text. For this purpose, you can use the eval function of JavaScript.
| | Learning curve
| Very hard as you need to learn technologies like XPath, XML Schema, DOM, etc.
| HTML is a simple technology stack that is familiar to developers.

Advantages of XMLHere, are significant advantages of XML: - Makes documents transportable across systems and applications. With the help of XML, you can exchange data quickly between different platforms.
- XML separates the data from HTML
- XML simplifies platform change process
Advantages of HTMLFollowing are advantages of HTML language: - HTML document browser interfaces are simple to build
- It works across a system which is otherwise unrelated.
- HTML is easy to understand because it
has a very simple syntax
- You can use many tags to make a webpage.
- Allows you to use various colors, objects, and layouts
Disadvantages of XMLHere, are few drawbacks of XML: - XML requires a processing application
- The XML syntax is very similar to other alternative ‘text-based’ data transmission formats which is sometimes
confusing
- No intrinsic data type support
- The XML syntax is redundant
- Does not allow the user to create his tags.
Disadvantages of HTMLHere, are few drawbacks of HTML: - HTML lacks syntax checking and structure
- HTML is not suitable for data interchange
- HTML is not context aware
- HTML doesn’t allow us to describe the
information content or the semantics of the document
- HTML is not object-oriented, so it, not an extensible and very unstable language
- Data storage and interchange of data are not possible using HTML.

Is XML better than HTML?
XML provides framework to define markup languages. HTML can ignore small errors. XML does not allow errors. HTML is not Case sensitive.
Why we use XML instead of HTML?
XML Separates Data from HTML
When displaying data in HTML, you should not have to edit the HTML file when the data changes. With XML, the data can be stored in separate XML files. With a few lines of JavaScript code, you can read an XML file and update the data content of any HTML page.
Does XML replace HTML?
1 Does XML replace HTML? No. XML itself does not replace HTML: instead, it provides an alternative which allows you to define your own set of markup elements. HTML is expected to remain in common use for some time to come, and a Document Type Definition for HTML is available in XML syntax as well as in original SGML.
Is XML stricter than HTML?
XML IS TEXT, BUT ISN'T MEANT TO BE READ
But the rules for XML files are much stricter than for HTML. A forgotten tag, or an attribute without quotes makes the file unusable, while in HTML such practice is often explicitly allowed, or at least tolerated.
