Panicking about XML to WML

Panicking about XML to WML?

• Here is some help

2
Recap

• You can use
• XML to store the data
• XSLT to transform the presentation of the data
  BUT No.1
• only if the output platform can process the
  XSLT and the XML file
• BUT No.2
• WAP browsers cant handle this processing

3
So how do you process XSLT for WAP?

• Well since you cant client side process it then
  you must server side process it
• Easiest method?
• Use ASP (or Coldfusion)

4
Using ASP

• Using Microsoft Document Object Model server code
  (DOM) you can execute and instance of an XML
  parser
• You call an ASP page which calls the DOM
• This will load the XML
• Then it will load the XSL
• The it process the XML through the XSL and
  outputs the file

5
ASP method

• lt
• '---Create an instance of the DOM object---
• Set xml Server.CreateObject("MSXML2.DOMDocument"
  )
• '---Let it run synchronously---
• xml.async false
• '---Load the XML document---
• xml.load (Server.MapPath("XMLCourse.xml"))
• Set xsl Server.CreateObject("MSXML2.DOMDocument"
  )
• xsl.async false
• '---Load the XSLT stylesheet---
• xsl.load (Server.MapPath("WML.xsl"))
• '---Set the MIME type---
• Response.ContentType "text/vnd.wap.wml"
• '---Send the WML prologue---
• Response.Write lt?xml version'1.0'?gt
  Response.Write "lt!DOCTYPE wml PUBLIC
  ""-//WAPFORUM//DTD " _ "WML 1.1//EN""
  ""http//www.wapforum.org/DTD/wml_1.1.xml""gt"
• '---Performs the transformation---
• Response.write (xml.transformNode(xsl))
• gt

Using Coldfusion

• lt!--- You want to work with the Company.xml file,
  ---gt
• lt!--- which is in the same folder as this CF
  template ---gt
• ltCFSET MyXmlFile ExpandPath("Company.xml")gt
• lt!--- Read XML file into string variable called
  MyXmlCode ---gt
• ltCFFILE ACTION"READ"
• FILE"MyXmlFile"
• VARIABLE"MyXmlCode"gt
• lt!--- You also need to work with your XSLT
  Stylesheet code ---gt
• ltCFSET MyStylesheet ExpandPath("TransformCompany
  .xsl")gt
• lt!--- Read XSLT file into string variable called
  MyXsltCode ---gt
• ltCFFILE
• ACTION"READ"
• FILE"MyStylesheet"
• VARIABLE"MyXsltCode"gt
• lt!--- Perform the XSLT Stylesheet transformation
  ---gt
• ltCFSET TransformedXmlCode XmlTransform(MyXmlCode
  , MyXsltCode)gt
