Form html updating xml
HTML rarely (if ever) provides information about how the document is structured or what it means.In layman’s terms, HTML is a presentation language, whereas XML is a data-description language.HTML’s sole purpose is to allow anyone to quickly create Web documents that can be shared with other people.XML, on the other hand, isn’t just suited to the Web – it can be used in a variety of different contexts, some of which may not have anything to do with humans interacting with content (for example, Web Services use XML to send requests and responses back and forth).However, XML allows you to define your own set of tags. It’s much more flexible than HTML because it allows you to create your own custom tags.
If you were presented with a list of these names and asked to provide a category that contained them all, it’s likely you’d say something like “female animals.” Furthermore, if I asked you what a lioness was, you’d say, “female lion.” If I further asked you to list associated words, you might say “pride,” “hunt,” “savannah,” “Africa,” and the like.
The others either roll their eyes in anticipation of hype and half-formed theories, or cringe in fear of a long, dry history of markup languages.
As a result, I’ve learned to keep my explanation brief.
I’ll try to stay away from the grandstanding hoopla that has characterized much of the discussion of XML; instead, I’ll give you the background and know-how you’ll need to make XML a part of your professional skillset. Whenever a group of people asks this question, I always look at the individuals’ body language.
A significant portion of the group leans forward eagerly, wanting to learn more.
Then, we’ll spend some time starting the project we’ll develop through the course of this book: building an XML-powered content management system.
