In the simple taglib example , I used a tag handler class to implement a taglib. This is an example to implement a taglib with a UI component. The purpose is to use a custom tag to split a string and print each part in a separate paragraph, i.e., print <p>john</p> <p>steve</p> <p>mike</p> with custom tag <my:foreach> : <my:foreach var="who" value="john steve mike"> ...

The tags <x:parse> Parses an XML document. The document to be parsed can be specified by the doc attribute or enclosed as the body of the tag. The parsed document is exposed as the var attribute or the varDom attribute. When exposed as var , the type of the exposed object is implementation dependent; when exposed as varDom , the type of the exposed object is org.w3c.dom.Document . Objects exposed by var and varDom can both be used to set the context of an XPath expression.

The tags <c:import> The <c:import> tag imports the contents of a URL and expose that in one of three ways: Import contents from a URL and write it out to the page (url may be relative or absolute): <c:import url="theUrl" /> Import contents from a URL and save it to a scoped variable string named by the var attribute.

IE and firefox both support client side XSLT. This can be done by inserting an xml-stylesheet into the XML file, which would trigger the browser to apply the XSL to the XML document and generate a transformed page: <?xml version="1.0" encoding="utf-8" ?> <?... Or, it can be done more dynamically with client side JavaScript. However, IE and FF offer different APIs for XSLT. Below is my attempt to bridge the differences. It's been tested to work for IE 7.0, FF 2.0 and Opera 9.0.2. function XSLT(url) { var xslt = false; ... The following HTML page shows how to use it: <HTML> <HEAD> <SCRIPT language="JavaS...
