What is The Difference Between PL/I And XHTML, Programming Languages

PL/I is a Procedural Programming Language, while XHTML is a Logic-based Programming Language

What are Procedural Programming Languages

Procedural (imperative) programming implies specifying the steps that the programs should take to reach to an intended state. A procedure is a group of statements that can be referenced through a procedure call. Procedures help in the reuse of code. Procedural programming makes the programs structured and easily traceable for program flow.

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 PL/I is a Procedural Programming Language, and XHTML is a Logic-based Programming Language

Let us now look at the difference between the two:

What is PL/I Programming Language – A brief synopsis

It is an imperative computer programming language targeted at scientific and engineering applications. Mainly intended to perform data processing, it also supports structured programming and recursion.

What is XHTML Programming Language – A brief synopsis

It is a markup language that is similar to HTML and follows the XML syntax. It is midway between HTML and XML. XHTML documents allow automated processing of data.
