If you missed the previous article that led to this one, you can find it here: http://www.devwebpro.com/2001/0720.html

Below are some of the mechanics of the language:

The Prologue, is the first part of your WML article. It contains information for the browser to let them know what kind of document it is and where they can find the rules (DTD) for this document. It usually is:
http://www.wapforum.org/DTD/wml_1.1.xml

<?xml version=”1.0″?>
<!DOCTYPE wml PUBLIC “-//WAPFORUM//DTD WML 1.1//EN”
“http://www.wapforum.org/DTD/wml_1.1.xml”>


Line Space and Formatting Tags

<wml>
<card title=”Horses”>
<p>
Welcome!<br/>To the <u>wonderful</u> world of <i><b>Horses</b></i>!
</p></card>
</wml>


Here is an example of making a table in WML (This too is the same as HTML):

<wml>
<card title=”TableofHorses”><p>
<table columns=”3″>
<tr>
<td>Thoroughbred Horses</td>
<td>Quarter Horses</td>
<td>Arabians</td>
</tr>
</table>
</p></card>
</wml>


<anchor>
When you use the anchor tag, you should use “go”, “prev”, or “refresh” tags to let the browser know what specific action to take.

<wml>
<card title=”HorseLinks”><p>
<anchor>Thoroughbreds
<go href=”thoroughbreds.wml”/>
</anchor>

<anchor>Arabians
<go href=”arabians.wml”/>
</anchor>

<anchor>Paints
<go href=”paints.wml”/>
</anchor>

</p></card>
</wml>


<a>
The <a> tag always performs a “go” task, with no variables. The example below does the same as the <anchor> tag example:

<wml>
<card title=”Secretariat1″><p>
<a href=”secretariat2.wml”>More Information</a>
</p></card>
</wml>


Image
>A WML card can be set up to display an image:

<wml>
<card title=”Picofsecretariat”> <p>
Here is a picture of Secretariat
<img src=”../images/Secretariat.wbmp” alt=”Secretariat” />
in a paragraph
</p></card>
</wml>


Input Fields

<wml>

<p>

Age: <input name=”Age” size=”15″ format=”*N”/><br/>
Sex: <input name=”Sex” size=”15″/>
</p>

</card>
</wml>


Select and Option Tags for Forms

<p>
<select>
<option value=”secretariat”>Secretariat</option>
<option value=”drfager”>Dr. Fager</option>
<option value=”spectacularbid”>Spectacular Bid</option>
</select>
</p>

</wml>

<p>
<select multiple=”true”>
<option value=”arabians”>Arabians</option>
<option value=”quarters”>Quarter Horses</option>
<option value=”saddlebred”>Saddlebreds</option>
</select>
</p>
