Difference Utilities to Compare HTML Extension Files

HTML or hypertext markup language is the most widely used markup language for content on the Internet. It is called markup language because it basically describes the classification of the various parts of a block of text (or hypertext). For instance, it can denote a particular phrase as a hyperlink, and also define where the hyperlink goes. It can denote some other phrase as a heading, a paragraph as body text, and so on. These various markups are then acted upon by web browsers and other programs for final display to the end viewers. When programming HTML, it becomes sometimes necessary to compare HTML extension files.

For example, when working on a large website, the HTML code can grow to hundreds or thousands of lines. A programmer is busy updating the site’s HTML to a newer version, when all of a sudden, errors pop up. He could go and look through the HTML code line by line in order to find out what parts changed, and subsequently which change caused the errors. But in larger HTML documents, such a line-by-line perusal could take too long, and can be overly tedious, too.

This is where utilities called difference programs can step in to help. These programs are specifically designed to be able to compare two blocks of code quickly and thoroughly. They will be able to find even the tiniest differences or changes that a human programmer might have trouble finding. These programs can be set up to highlight any such changes quickly to make them easier to spot. The programmer can then more quickly and easily act on such changes, especially if they turn out to be typos or errors.

Aside from these utilities, there are also quite a wide variety of HTML helpers that can make the entire programming process easier. These programs can provide interfaces or front-ends to make editing or creating HTML documents more user-friendly. For example, a lot of these editors highlight delimiters and HTML keywords to make it easier to see the structure of the document. They can also provide automation and other easier ways to make extensive changes to an HTML file.

Apart from debugging or updating purposes, these difference utilities and HTML editors may be used for learning purposes. Novice HTML programmers often find it instructive to look at the source code of many different websites. For similar HTML documents, it may be a little difficult for the novice to spot the changes. Using these utilities, the HTML student would be able to more easily understand how two HTML documents are different, and what the effects of these differences are.

HTML is a very widely used language that is essential for any web developer. The various utilities mentioned here are bound to be useful tools, in the right situations. For any HTML programmer, from webmasters of big sites to novices who are just learning, the proper use of these utilities is invaluable. Learning how to use them can mean tons of saved labor. Get on with these so that you can compare HTML extension files faster and more efficiently.
