  1. WAP’s WMLby David Boncarosky • WML Inherits From XML • WML Extends Interactivity to Cell Phones, Pagers, PDAs • Display Varies Widely From Device to Device • WML tags lack consistency across different manufacturers

  2. WML Coding • WML Based on a Deck of Cards -- the device only shows 1 card at a time • Cards in a Deck can Interact with other Cards in Deck and Cards in External Decks

  3. WML Coding • All WML documents MUST have a specific header • The Deck is delimited by the <wml> . . . </wml> tag <?xml version="1.0"?> <!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml"> <wml> <card id="main" title="First Example"> <p>Hello World!</p></card> </wml>

  4. Entering Text • Cards are delimited by the <card> . . . </card> tags • All Text within a card must be placed in <p> . . . </p> tags <wml> <card id="main" title="Hello World"> <p> My First WML Card! (a.k.a. Hello World!) </p> </card> </wml>

  5. WML Anchors (links) • Similar to HTML links • <a href=“address”> text </a> • Use # to reference a card (e.g. href = “#myCard”). Otherwise, will go to the first card in a deck <wml> <card id="main" title=“Link Example"> <p> <a href="#anotherCard"> My First link </a> </p> </card> </wml>

  6. WML sample Site <?xml version="1.0"?> <!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml"> <wml> <template> <do type="accept" label="Find a Person"> <go href="#search" /> </do> <do type="accept" label="School Info"> <go href="#schools" /> </do> <do type="accept" label="My CMU email"> <go href="#login" /> </do> </template>
