What is The Difference Between XML And Janus, Programming Languages

XML is a Markup Language, while Janus is a Logic-based Programming Language

What are Markup Languages

A markup language is an artificial language that uses annotations to text that define how the text is to be displayed.

What are Logic-based Programming Languages

Logic programming is a type of programming paradigm which is largely based on formal logic. Any program written in a logic programming language is a set of sentences in logical form, expressing facts and rules about some problem domain. (Wikipedia)

While XML is a Markup Language, and Janus is a Logic-based Programming Language

Let us now look at the difference between the two:

What is XML Programming Language – A brief synopsis

The name stands for Extensible Markup Language. It is extensible because it allows the users to define their own XML elements. It supports the sharing of structured data over the Internet and the encoding and serializing of data. It originated as a subset of SGML. XPath is the XML Path Language that is used to select nodes from an XML document. It supports the computation of values. XQuery is used to query the collections of XML data. Extensible Stylesheet Language Transformations (XSLT) is an XML-based language that is used for the transformation of XML documents into human-readable formats. Apache Ant is a tool for the automation of software build processes. It uses XML to describe the build processes.
