The world of web is becoming popular with each passing day. People are turning to the web for all kinds of purposes, be it for business or spiritual upliftment. The internet has become a great source of information which can be accessed by anyone from anywhere. Being an internet user is completely different from being a website-maker. Making websites requires skills and expertise in HTML and certain programming languages. HTML stands for Hyper Text Markup Language and XML stands for Extensible Markup language. HTML came into existence much before XML.
XML was created in 1996 by a set of 11 people and it was derived from SGML which stands for Standard Generalized Markup Language. The basic job of XML was to simply store and carry data as it is. The fact that XML uses general terms makes it very easy to understand and use. Its usability also makes it very convenient and a language of choice for a lot of webmasters. A number of languages have been developed recently which are based on XML. These languages are RSS, XHTML, SOAP and Atom. A lot of MS office productivity tools, by default, use XML based files. The processor of XML is also known as a parser. An XML processor typically goes through the code and the passes it on to an application.
The basic difference between the two languages is the goal they have. The basic goal of HTML is to decide how the data in a website will be displayed. The goal of XML is to simply contain the data. The tags and pre-defined codes exist in HTML which decides how a web page will be displayed. In XML, the file that is created has no pre-defined terms or codes. Whatever is written can easily be understood for what it is because it is quite self-explanatory. Words or terms can be created by the webmaster and then be saved in a file. Many website designers create their own terms which can be related to the business of their clients. It is easy for people who do not get HTML too well and think that codes complicate things rather than making it easy to use.
There is also a sense of clarity in XML compared to HTML. HTML needs to be learnt more vigorously by the webmasters than XML. HTML has different tags for providing layout and design of a webpage. It also has a particular structure to the coding which has to be followed while creating a website. HTML is used for displaying online pages which may have graphics, sound or video files. Hypertext links can also be used to view information contained in a website.
Certain websites which are extension to a business require monetary transactions to take place. HTML caters for such requests also. These services include transferring money from one account to another in banking websites, book train or air tickets through travel websites and many similar actions. HTML is also capable of including excel sheets and other such documents directly as part of a website. W3C maintains and keeps modifying HTML by updating it from time to time.
