Eine WML Plattform mit zwei Karten - eine für Benutzer eingeben und eine für das Anzeigen des Resultats - kann aufgestellt werden, wie in diesem Beispiel demonstriert worden, das Gebrüll gegeben wird:
<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
"http://www.wapforum.org/DTD/wml_1.1.xml">
<card id="card2" title="Answer">
<p>
You selected: $(name)
</p>
</card>
</wml>
You selected: HTML
Example Explained
The first lines in the WML document are called the prolog. The prolog defines that this is an XML document, it then defines the version of the XML , and the DTD to be referenced.
The Deck
<wml> ..... </wml>
The deck is the WML document itself. It is embedded within <wml> tags
The Cards
<card> ..... </card>
Cards are always displayed one at the time. This WML deck contains two cards - one for user input and one for displaying the result.
The <do>element
<do> ..... </do>
The first card has a <do> element that defines an event to be triggered. The type="accept" attribute of the <do> element causes the label="Answer" to be displayed in the lower left corner of the display.
The Event
The <go> element triggers when the user clicks the <do> label. The href="#card2" attribute of the <go> element causes card2 to be displayed on the screen.
The Variable
Card2 displays the $(name) variable from card1, because variables are valid across cards.
