› Used to transform XML documents to other formats ,like HTML or other XML documents

It uses XPATH to navigate thro XML docs

Elements and attributes can be added/removed from the document

XSLT uses XPATH to define parts of the source document that should match one or more predefined templates

When a match is found ,XSLT transforms the matching part of the source document into result document

Create an XSL Style Sheet

xsl:stylesheet is the root element

Link the Style sheet to XML document

<xsl:stylesheet version="1.0” xmlns:xsl="http://www.w3.org/1999/XSL/Transform”

<?xml-stylesheet type="text/xsl" href="cdcatalog.xsl"?>”

Template consists of rules to apply when a matching node is found

xsl:template is used to build template The match attribute is used to associate

a template with an XML element. The value of the match attribute is an

XPath expression

Match=“/” is defines the whole document

<xsl:template match="/“>

<?xml version="1.0" encoding="ISO-8859-1"?>

<?xml-stylesheet type="text/xsl" href=“name.xsl"?>

<program><btech> <name>Arun</name> <regno>10BIT001</regno> <cgpa>9</cgpa></btech>

</program>

<?xml version="1.0" encoding="ISO-8859-1"?><xsl:stylesheet version="1.0"xmlns:xsl="http://www.w3.org/1999/XSL/Transform"><xsl:template match="/"> <html> <body> <h2>Students Name List</h2> <table border=‘1’> <tr bgcolor=‘white’> <th>Name</th> <th>Register No</th> </tr> <xsl:for-each select=“program/btech”> <tr> <td><xsl:value-of select=name"/></td> <td><xsl:value-of select=“regno"/></td> </tr> </xsl:for-each> </table> </body> </html></xsl:template></xsl:stylesheet>

Save as Program.xml (top)Save as Name.xsl (right)

Open the program.xml file in a browser

Used to extract the value of a selected node

<td><xsl:value-of select=name"/></td> <td><xsl:value-of select=“regno"/></td>

Used for looping through XML document

<xsl:for-each select=“program/btech”> <tr> <td><xsl:value-of select=name"/></td> <td><xsl:value-of select=“regno"/></td> </tr> </xsl:for-each>

Used for conditional testing against the content of the XML document

<xsl:if test=“expression”> 

</xsl:if>

<xsl:for-each select=“program/btech”><xsl:if test=“cgpa > 9“> <tr> <td><xsl:value-of select=name"/></td> <td><xsl:value-of select=“regno"/></td> </tr></xsl:if></xsl:for-each>

Used for conditional testing against the content of the XML document

<xsl:if test=“expression”> 

</xsl:if>

<xsl:for-each select=“program/btech”><xsl:if test=“cgpa > 9“> <tr> <td><xsl:value-of select=name"/></td> <td><xsl:value-of select=“regno"/></td> </tr></xsl:if></xsl:for-each>
