Extensible Stylesheet Language (XSL) is an XML-related technology which is used to transform XML data. XML files are used to set the ground-rules for a given body of data and to describe the data itself. XSL allows us to take that data and convert it into information which can be displayed in a web browser window or opened with a text editor. It can also be used to create an XML file which is a modified version of an original XML file.

When displaying elements in a browser window, the XSL elements which enable looping through an XML tree and decision-making really come into their own. One of the key methods used in XSL for looping through XML elements is the “For-each” element. This uses the “select” attribute to specify which element is to be targeted in the loop. The “For-each” element has both an opening and a closing tag and any lines of code placed between the opening and closing tags will be repeated each time the element specified in the “select” attribute is encountered in the XML file.

For example, let’s say we have an input XML file containing a list of companies and the addresses of their websites. Let’s also say that the element which we will be targeting in the XSL “For-each” statement is called “company” and that, for each company element, we have a “name”, “telephone” and “website” element. Before beginning our “For-each” loop, we could output the opening tag of an HTML “ul” element (an unordered or bulleted list).

Inside the “For-each” loop, we could output an HTML “li” element and, between its opening and closing tags, output the contents of the “name” and “telephone” elements from the XML file. The data in the “website” element in the input XML could be used to convert the “name” into a clickable link.

As regards the appearance of the data in the resulting HTML output, this would be controlled by a linked CSS file. CSS can be used to format the output in any way we desire, so our bulleted list can take on pretty much any appearance we care to give it.

JavaScript and AJAX is a well-established and important web technology. Computers are becoming the center of operations for a lot of large companies, so wouldn’t you like to get in the middle of this frenzy with JavaScript training? This training has actually not been out as long as you may have figured.

If you know someone that has just finished a technical school or a computer school, one thing that a lot of these people say is they feel that they were missing out on some training that they should have had. In fact, in the past a lot of institutes didn’t even offer classes for this explicit training.

If the term JavaScript sounds foreign to you, you may not be extremely computer savvy. This term actually refers to a client based language that literally embeds itself into our web browsers. Your web browser are programs such as Internet Explorer and Firefox.

The script was first used in 1995. Upon being released the script was given the name LiveScript, which was later changed to the modern term JavaScript that we all know it by today.

This script, in an essence is a little miracle worker. It allows any website that you are looking at to come to life. Without this script, an HTML code would not be able to make the impressive banners and add-ons like they presently do now.

JavaScript is actually what unlocks all the exciting features that you can view on modern day web pages. This script allows an immense amount of benefits to be able to take place such as performing calculations, allowing users to have an interactive website, and enabling awesome visual effects.

It is kind of difficult to try to think back to what the internet looked like before this script was made. For people that remember this time fondly, it shows how far technology has been able to progress over such a short period of time.

JavaScript because it is a client based programming all of the features that you see on a website are all done to real time. With it being at real time no one has to worry about any delays, and the overall satisfaction factor can be accomplished.

There are a plethora of different places that you can obtain JavaScript training from. Obtaining this training will help you get your start with a brand new and lucrative career. It’s a great move to make during this time of our economies decline.
