XML(Extensible Markup Language) and 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 Errorsand 
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. andlt;HTMLandgt; tag needs an equivalent andlt;/HTMLandgt; tag but andlt;brandgt; tag does not require andlt;/brandgt; 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 and 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
