IBM Version 5 manual Generate XML file, Design an output, Html and mapping approach

9.1.5 Generate XML file

Now we are going to generate the XML File and add some sample data to it. This data it’s going to be transformed and presented in a HTML output page.

1.Select passengerList.xsd.

2.Right-clickGenerate—>XML File.

3.Select Airline as the folder name.

4.Enter passengerList.xml as the filename, click Next.

5.Select Flight as root element, select Create required and optional content, click Finish.

We need to add some sample data to the XML file. (See Example 9-2.)

Example 9-2 Static XML file

<?xml version="1.0" encoding="US-ASCII"?>

<passenger:Flight departure="8:00pm" flightNo="Air Canada 700" xmlns:passenger="http://www.airline.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.airline.com passengerList.xsd ">

<passenger:Customer> <name>John Doe</name> <membership>123456</membership>

</passenger:Customer>

</passenger:Flight>

9.1.6 Design an output page

Since XML is not a markup language specialized in presentation, we are going to design an HTML output page to show the data. XSL Transformations (XSLT) will be used to transform the XML to HTML data. To create the XSL, there are several approaches as follows:

1.Design an HTML file, then map to the XML using mapping tool. We can use XSL generator to generate the XSL using the map file.

2.Develop the XSL from scratch. We can use the different wizards in the XSL editor.

3.Design an XHTML file then generate the XSL file.

HTML and mapping approach

Using this approach, we created a DTD file first. Then generate the XML which contains HTML tags. Given the XML definition, we can think of HTML as a sub set of XML. We need to map the static XML file data to HTML tags, in order to be able to use the XML to XML mapping tool, we are going to create the file html.dtd, and generate html.xml. (See Example 9-3.)
