XML Basics

XML stands for eXtensible Markup Language. XML is used to aid the exchange of data. The language makes it possible to define data in a structured way. XML tags are not predefined like HTML. XML lets you create your own unique tags that are meaningful for your data, hence the use of the term 'extensible.'

XML in Brief

XML is the acronym for the extensible markup language. According to the W3C, it is 'the universal format for structured documents and data on the Web'. The following list explains what XML is and what it is not.

XML is Like...

Maybe XML is more like a carcinogen. We don't notice it's there, but we're still getting exposed to it. In ever-increasing doses. But unlike a carcinogen, XML is not bad for our health; in fact, it has many life-enhancing properties. Well, work-enhancing properties.

XML Tips

Extensible Markup Language, or XML, is currently the most promising language for storing and exchanging information on the World Wide Web. Although Hypertext Markup Language (HTML) is presently the most common language used to create Web pages, HTML has a limited capacity for storing information. In contrast, because XML allows you to create your own elements, attributes, and document structure, you can use it to describe virtually any kind of information—from a simple recipe to a complex database. And an XML document—in conjunction with a style sheet or a conventional HTML page—can be easily displayed in a Web browser.

XrML and Emerging Models of Content Development and Distribution  

With the publication of XrML 2.0, ContentGuard provides an open, flexible, and extensible means of expressing digital rights that not only addresses copy protection, but, as importantly, offers a much broader and powerful means for publishers to experiment with and deploy new business models.

Year Zero

I am as frustrated as any other web developer at the glacial pace of the CSS Working Group and the lack of progress with CSS3. I just don't think we need to dump the baby out with the bathwater. Change is needed. It looks like change is coming. It may even be a regime change. But let's not start drawing up new calendar systems just yet. The clock of CSS is running slow. We need to wind it up. That doesn't mean we need to smash it.

Yellow Screen of Death

In Mozilla-based applications, the yellow screen of death is the screen displayed when they encounter an XML parsing error. This typically happens when the XML document that the browser is trying to access is not well-formed, for example when it does not nest tags properly.

The History of the Internet and the Web, and the Evolution of Web Standards

a brief overview of the creation of the Internet, the World Wide Web, and the "web standards" that this entire series focuses upon. I think it is useful and interesting to understand how we got to where we are, but it will be short enough so you don’t get overwhelmed, and can get into the details nice and quickly.

The Web Standards Model: HTML, CSS and JavaScript

You can accomplish content, styling and layout just using HTML—font elements for style and HTML tables for layout, so why should I bother with this XHTML/CSS stuff? Here are the most compelling reasons for using CSS and HTML over outdated methods.

Web Standards – A Beautiful Dream, But What's the Reality?

Web standards allow for interoperability between all web browsers, on every operating system, and even on every electronic device available. But is that really reality? The really simple answer is no; while that’s an ideal situation, that is far from reality.

Acid Redux

I fully acknowledge that a whole lot of very clever thinking went into the construction of Acid3 (as was true of Acid2), and that a lot of very smart people have worked very hard to pass it. Congratulations all around, really. I just can’t help feeling like some broader and more important point has been missed.

Helping Others Understand Web Accessibility

When I hold workshops for people who want to learn more about web standards and accessibility, I often notice that the attendants really have tried to improve their accessibility knowledge. But they get overwhelmed when they go to the official documentation from the W3C and try to understand it.

Beyond DOCTYPE: Web Standards, Forward Compatibility, and IE8

Progress always comes at a cost. In the case of web browsers, users bear the cost when developers take the rendering of certain authoring tools and browsers (especially Internet Explorer) as gospel. We could spend hours explaining why our sites broke, but wouldn’t it be better if they didn’t break in the first place?

From Switches to Targets: A Standardista's Journey

Version targeting allows browsers to much more easily develop new features and fix bugs and shortcomings in existing features, which has the potential to speed up the evolution of web design and development. That alone is reason enough to give it a chance.

Accessibility is Part of Your Job

Accessibility is one of the fundamentals of the Web, so how people who claim to be passionate about the Web and say that they deliver high quality can choose to ignore it is beyond me.

Keep Browser Lock-Out a Thing of the Past

Browser sniffing and deliberately preventing people using a so-called unsupported browser from entering a site is a thing from the past that we do not need these days.

POSH: Plain Old Semantic HTML

POSH, in case you haven’t heard of it already, is short for “Plain Old Semantic HTML”, and is obviously much quicker and easier to say than “valid, semantic, accessible, well-structured HTML”. Unfortunately POSH - semantic markup - is also something most people building websites or creating content for the Web have yet to discover.

One thing that is particularly frustrating with caring about Web standards and accessibility is what often happens after your work is done and a site is handed over to the client.

Avoid the Void

There are plenty of occasions when coding JavaScript events where you simply need to call a function, for which an entire event registration model is too lengthy. The most commonly used method is to bind your event to an anchor link. The user clicks and the onclick event is fired, calling a reference to a function. Because the user isn’t actually visiting a URL, something has to be done with the href attribute.

The Two Fundamental and Opposing Views of the Web

Conventional wisdom states that a standardized set of computer communication languages, which every device understands, is a necessary component of interoperability. The most popular of these languages being Hypertext Markup Language (HTML). However, in order for this idea to come to fruition, all hardware and software vendors must come to a consensus on implementation techniques, as well as features and functionality. As the Web continues to grow, and the cost of developing new technology decreases, this becomes increasingly difficult to manage.
