XSL Tags

• What is XSL
• separate the commands from the output using namespaces
• specifically: the xsl:namespace (where we tell the path, and type of namespace)

• XSL basics are different for IE5 and IE6
• For earlier versions of IE5 and Netscape
• Use either attributes or elements, not both if you need to display the data (this version only allows access to one or the other)
• use namespaces and asp includes to combine data
• Use a server function to connect the two, this converts both to html and allows our data to be seen in any browser
• For IE6 and Netscape 6.0
• Use XSLT (xsl stylesheet --XPath, XPointer, etc)
• use variables and parameters
• make your presentation independent of the cascading tree of the xml document
• Use DOM
• Use import and include to include your own libraries, with display set up
• the document() function allows you to include multiple XML documents, and pass requests to other servers

• Why use xsl
• Does the mechanics of displaying xml
• converts tree document to presentation
• formatting vocabulary describes presentation for layout, typesetting, etc.
• Sets the order of displaying the data
• Can use "includes" to set up your heading and/or navigation on other pages
• Can use "excludes" to exclude certain types of tags from your schema or dtd
• Allows you to sort and search to choose what to display
• can convert to vector graphics -for graphs (see SVG)

Connecting

• attach a java bean
<link rel="stylesheet" href="mystyle.css" type="text/css" />
• attach a javascriptlet - with regular html tags (it works)
<script src="archive.js" language="JavaScript"></script>
• attach a java bean
<bean class="java.awt.Panel" id="mailPanel">
<add><bean class="java.awt.Label">
<property name="text" value="This is a label"/>
</bean> </add></bean>
• attach a javascriptlet, activeX,or plug-ins
<OBJECT width=100 height=300 TYPE="text/x-scriptlet" DATA="jjscriptlet.htm"></object>
• from XML to XSL
<?xml-stylesheet type="text/xsl" href="Root.xsl"?>
• from XML to ASP

<?xml-stylesheet type="text/xsl" href="propertiesdemo.asp"?>

Two common XSL namespaces:

• Internet Explorer 5.0

<?xml version='1.0'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl">

• Internet Explorer 6.0

<?xml version='1.0'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

 

-- only for 6.0

<xsl:apply-templates/>

Makes for modular programming with xml
