Listing 1:transform.xsl file
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:param name="doc"/> <xsl:template match="/"> <html> <body> <h2>Company's Employee detail</h2> <table border="1"> <tr> <th align="left">name </th> <th align="left">designation </th> <th align="left">age </th> </tr> <xsl:for-each select="org/company/emp"> <tr> <td> <xsl:value-of select="name"/> </td> <td> <xsl:value-of select="designation"/> </td> <td> <xsl:value-of select="age"/> </td> </tr> </xsl:for-each> </table> </body> </html> </xsl:template> </xsl:stylesheet>

Listing 3:JSP file-example.jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml" %>
<c:import var="xml" url="transform.xml" />
<c:import var="xsl" url="transform.xsl" />
<x:transform xml="${xml}" xslt="${xsl}" />
