Programming

By Chadburgard ·
I am just beginning to learn different forms of programming. I'm starting to notice that HTML, XML, JAVA, and Visual Basic are all pretty much the same, with the exception of a few rules. I have noticed that several books on Java and Visual Basic talk about and start discussing XML. From what I have studied on HTML it?s really similar to XML. Am I right, or way off?

HTML and XML are two different programmings.
XML .. Short for Extensible Markup Language, a specification developed by the W3C. XML is a pared-down version of SGML, designed especially for Web documents. It allows designers to create their own customized tags, enabling the definition, transmission, validation, and interpretation of data between applications and between organizations.
HTML (hypertext markup language) is a mark up language for the Internet. With the help of tags, it allows the markup of content according to predefined categories for web documents: Titles, paragraphs or hyperlinks can be interpreted and displayed by web browsers. The advantage of HTML is that the structure of the predefined markup tags is very simple. However, it is not possible to reflect any content-oriented structures with the markup-any content-oriented classification will be lost. Complex database and object structures cannot be mapped with HTML.
There is a written language to convert XML to HTML.

XML and HTML are mark-up languaes - as is SGML - for formatting information; they specify the arrangement of the data that flows through their pages.

Java and Visual Basic are object-oriented algorithmic languages. Other algorithmic languages areCobol, Algol, Fortran and Basic. The object-oriented languages tend to take their structures from Algol, especially Algol 68 - indeed, if Algol 68 had been implemented more widely we would nowadays be using Algol something where we in fact use Java and VB.

"Programming Languages" by Jean Sammet describes and relates a lot of languages, but it was written quite a while ago so it does not cover those you are learning; still, it will give you the history within which those have evolved.

First of all, get your concepts straight.
HTML is a language you use to create web pages. It has to do with layout (the way things look), and there is no logic involved besides they way in which you present things on your documents. XML was created with the purpose of enabling data sharing between different clients, companies, etc. What XML does is separate the data from the layout, in an organized way that someone else can later on read. As for Visual Basic and Java, this are object orientedlanguages, that you would use mainly to create applications. Microsoft made a scripting engine based on VB that you use on the Internet. It is known as VBScript, and you use it on your pages to make them DYNAMIC, and HANDLE ALL THE LOGIC. See the difference now?
You have probably seen Active Server Pages before right? (e.g. index.asp). Active server pages is another VB based parser that handles code written in VB included in web pages. What this one will do is receive the code of the page you request when browsing the Internet, and execute all the code on the server before sending the HTML output back to your browser.
VBScript and ASP are both "reduced set" versions of Visual Basic and do not support all the functionality of VB.

Good Luck!
