XML(Extensible Markup Language) & HTML(Hypertext Markup Language)

Parameter
XML
HTML
Type of language
The XML is a framework for specifying markup languages.
HTML is predefined markup language.
Language type It is Case sensitive.
This is Case insensitive
Structural details This is provided.
This is not provided.
Purpose The Transfer of data.

The Presentation of the data

Coding Errors  Into the XML no coding errors are allowed.
Here Small errors are ignored.
Whitespace
We can use white-spaces in our code.
We can't use white spaces in our code.
Nesting
Should be done appropriately.
Does not have any effect on the code.
Driven by
The XML is content-driven‭‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬.
The HTML is format driven‭. ‬‬‬‬‬‬‬‬‬‬‬‬‬‬
End of tags
Here the closing tag is essential in a well-formed XML document.
Here 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. ‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬
The 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
Importance 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.

Html does not support the concept of namespaces. The naming collisions can be avoided either using a prefix in an object member name or by nesting objects.
Formatting decisions
XML types and attributes required a more significant effort to map application types.
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
An XML DOM implementation and application code are required to map text to JavaScript objects.
No extra application code required to parse text. For this purpose, you can use the eval function of JavaScript.
Learning curve
Much difficult as you need to learn technologies like XPath, XML Schema, DOM, etc. HTML is a simple technology stack that is familiar to developers.

Conclusion

  • The XML is a markup language which is designed to store data. It's popularly used or transfer of data.
  • The HTML is the markup language which helps you to create and design web content.
  • The XML tags are not predefined. You need to define your customized tags.
  • The HTML provides support for multimedia embedding in documents
  •  With the help of XML, you can exchange data quickly between different platforms.
  • The HTML works across a system which is otherwise unrelated
  • The XML intrinsic data type support
  • The HTML lacks syntax checking and structure
