Like a natural language, there are two parts to a markup language: its vocabulary and its grammar. The vocabulary tells you the names of the components that you can use in a document. Those things are Elements like <P> and <A> Attributes like class and href Entities like and é QR Encoder In None Using Barcode maker for Font Control to generate, create QR Code ISO/IEC18004 image in Font applications. www.OnBarcode.comPainting UCC - 12 In None Using Barcode creation for Font Control to generate, create GTIN - 12 image in Font applications. www.OnBarcode.comCHAPTER 1 INTRODUCING XML

These are rules like the following: An <A> element has an href attribute A <UL> element can contain one or more <LI> elements The <HEAD> element must contain a <TITLE> element Now, you could imagine a different markup language that uses a different vocabulary and grammar. Instead of a <P> element, it might use the name <para>; rather than having <H1> to <H6> for headings, it might use <section> elements with <title> elements inside them, and so on.

Identifying those parts is important for two reasons: It affects the way that information looks on the page. The presentation of a piece of content is often tied to its meaning. If we had elements to indicate the meaning of these words and phrases, we would be able to display them in different ways with CSS. It helps other people, and more importantly applications, look at the page and draw some conclusions about the information that it contains. If we used <B> to indicate the program s title and the name of a character, then all an application could tell was that those phrases should be in bold. If we had more descriptive element names, like <title> and <character>, then the application could distinguish between the two and could actually make use of that information.

This is fine as far as it goes, but it doesn t give us the flexibility and control that an element and attributes would. For example, currently the TVGuide.html HTML page contains the following structure for cast lists: <UL class="castlist"> <LI> <SPAN class="character">Zoe Slater</SPAN> <SPAN class="actor">Michelle Ryan</SPAN> Make DataMatrix In Visual Studio .NET Using Barcode drawer for Reporting Service Control to generate, create DataMatrix image in Reporting Service applications. www.OnBarcode.comPrinting QR Code ISO/IEC18004 In Objective-C Using Barcode creation for iPad Control to generate, create QR Code JIS X 0510 image in iPad applications. www.OnBarcode.comCHAPTER 1 INTRODUCING XML
<LI> <SPAN <SPAN <LI> <SPAN <SPAN </UL>
class="character">Jamie Mitchell</SPAN> class="actor">Jack Ryder</SPAN> class="character">Sonia Jackson</SPAN> class="actor">Natalie Cassidy</SPAN> In this structure the cast list contains a number of character-actor pairs, but there s nothing in the grammar of HTML that determines this it s just a rule that we know about. We assume that this rule holds true in the CSS that we use to present the cast list. Instead, we could design a markup language that uses elements to mark up the cast list as shown in Listing 1-2. Listing 1-2. castlist1.xml <castlist> <member> <character>Zoe Slater</character> <actor>Michelle Ryan</actor> </member> <member> <character>Jamie Mitchell</character> <actor>Jack Ryder</actor> </member> <member> <character>Sonia Jackson</character> <actor>Natalie Cassidy</actor> </member> </castlist> Using elements means that it s easy to write the grammar for the cast list: <castlist> elements contain one or more <member> elements. <member> elements contain a <character> element followed by an <actor> element. <character> and <actor> elements contain text. It also means that we can add attributes to these elements if we want to, perhaps indicating the gender of the different characters as we do in Listing 1-3. Listing 1-3. castlist2.xml <castlist> <member> <character gender="female">Zoe Slater</character> <actor>Michelle Ryan</actor> </member>
