XSL stands for EXtensible StylesheetLanguage, and is a style sheet languagefor XML documents.

XSL consists of three parts: XSLT - a language for transforming XML

documents

XPath - a language for navigating in XML

documents XSL-FO - a language for formatting XML

documents

In the transformation process, XSLT usesXPath to define parts of the sourcedocument that should match one or morepredefined templates. When a match isfound, XSLT will transform the matchingpart of the source document into the result

document.

The root element that declares the documentto be an XSL style sheet is or

To get access to the XSLT elements,attributes and features we must declare theXSLT namespace at the top of the document.

We wantto transform thisXML document

("cdcatalog.xml") intoXHTML

Create an XSL StyleSheet

Link the XSL StyleSheet to the XMLDocument

Link the XSL Style Sheetto the XML Document

An XSL style sheet consists of one or more set ofrules that are called templates.

A template contains rules to apply when aspecified node is matched.

The element is used to buildtemplates. The match attribute is used to associate a

template with an XML element. The match attributecan also be used to define a template for the entire

XML document. The value of the match attribute isan XPath expression (i.e. match="/" defines thewhole document).

The element can be used toextract the value of an XML element andadd it to the output stream of thetransformation

The XSL element can beused to select every XML element of aspecified node-set

Filtering the Output Legal filter operators

are: = (equal)

!= (not equal) < less than

> greater than


15/23

To sort the output, simply add an element inside the elementin the XSL file

17/23

To put a conditional if test against thecontent of the XML file, add an element to the XSL document.

19/23

The element is used inconjunction with and to express multipleconditional tests.

21/23

The element appliesa template to the current element or to thecurrent element's child nodes.

If we add a select attribute to the element it willprocess only the child element thatmatches the value of the attribute. We canuse the select attribute to specify the orderin which the child nodes are processed.
