WAPs 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

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

WML Coding

• All WML documents MUST have a specific header
• The Deck is delimited by the ltwmlgt . . . lt/wmlgt
  tag

lt?xml version"1.0"?gt lt!DOCTYPE wml PUBLIC
"-//WAPFORUM//DTD WML 1.1//EN" "http//www.wapforu
m.org/DTD/wml_1.1.xml"gt ltwmlgt ltcard id"main"
title"First Example"gt ltpgtHello
World!lt/pgtlt/cardgt lt/wmlgt

Entering Text

• Cards are delimited by the ltcardgt . . . lt/cardgt
  tags
• All Text within a card must be placed in ltpgt . .
  . lt/pgt tags

ltwmlgt ltcard id"main" title"Hello
World"gt ltpgt My First WML Card! (a.k.a. Hello
World!) lt/pgt lt/cardgt lt/wmlgt

WML Anchors (links)

• lta hrefaddressgt text lt/agt
• Use to reference a card (e.g. href
  myCard). Otherwise, will go to the first card
  in a deck

ltwmlgt ltcard id"main" titleLink
