JSTL XML <x:transform> Tag

The <x:transform> tag is used in a XML document for providing the XSL (Extensible Stylesheet Language) transformation. It is used for transforming xml data based on XSLT script.

The syntax used for including the <x:transform> tag is:

Let's see the simple example to understand the xml <x:transform> tag:

Let us put the following program in transfer.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="2">
<tr>
<th align="left">Name
</th>
<th align="left">Designation
</th>
<th align="left">Age
</th>
</tr>
<xsl:for-each select="organisation/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>

Now put the following program in transfer.xml, keeping in the same directory:

<?xml version="1.0" encoding="UTF-8"?>
<organisation>
<company>
<emp>
<name>Rajan Singh</name>
<designation>Bussiness Developer</designation>
<age>40</age>
</emp>

<emp>
<name>Supriya Gaur</name>
<designation>HR Executive</designation>
<age>22</age>
</emp>
</company>

<company>
<emp>
<name>Shashnak Singhal</name>
<designation>Sr. Java Programmer</designation>
<age>26</age>
</emp>

<emp>
<name>Hemant Kishor</name>
<designation>Sr. PHP Programmer</designation>
<age>23</age>
</emp></company></organisation>

Now put the following program in index.jsp, keeping in the same directory:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml" %>
<html>
<head>
  <title>x:transform Tag</title>
</head>
</html>
<c:import var="xml" url="transfer.xml" />
<c:import var="xsl" url="transfer.xsl" />
<x:transform xml="${xml}" xslt="${xsl}" />

Output:
