It would be smarter, from an architectural point of view, to have a separate listing of actors with unique IDs to which you could link. Familiar examples are the img and br elements in HTML. Remember that in XML all opening tags must be matched by a closing tag.
For empty elements, you can use a single empty-element tag to replace this: Entities I mentioned entities earlier. An entity is a handy construct that, at its simplest, allows you to define special characters for insertion into your documents.
XML, true to its extensible nature, allows you to create your own entities.
More than Structure… XML documents are more then just a sequence of elements. The documents are really a hierarchy of nested objects.
This feature, combined with all that content encapsulated in opening and closing tags, takes all XML documents far past the realm of mere data and into the revered halls of information. Data can comprise a string of characters or numbers, such as But the only way to turn this data into information and therefore make it useful is to add context to it — once you have context, you can be sure about what the data represents.
When you take into account the second point — that an XML document is really a hierarchy of objects — all sorts of possibilities open up. Remember what we discussed before — that, in an XML document, one element contains all the others? Well, that root element becomes the root of our hierarchical tree.
You can think of that tree as a family tree, with the root element having various children in this case, product elementsand each of those having various children name, description, and so on. In turn, each product element has various siblings other product elements and a parent the rootas shown in Figure 1.
The logical structure of an XML document. Because what we have is a tree, we should be able to travel up and down it, and from side to side, with relative ease.

Before, we talked about transforming data into information by adding context. Formatting Issues Earlier in this chapter, I made a point about XML allowing you to separate information from presentation.
For example, if you stored your information in a word processing program, it would contain all kinds of information about the way it should appear on the printed page — lots of bolding, font sizes, and tables.
Unfortunately, if that document also had to be posted to the Web as an HTML document, someone would have to convert it either manually or via softwareclean it up, and test it. If yet another person wanted to take the same information and use it in a slide presentation, they might run the risk of using outdated information from the HTML version.
As you can see, it can get pretty messy! If you made changes to the XML file, the other files would also change automatically once you passed the XML file through the process.The transporter was a subspace device capable of almost instantaneously transport an object from one location to another, by using matter-energy conversion to transform matter into energy, then beam them to or from a chamber where they were reconverted back into their original pattern.
