Phrame Example: Xml class
This is a short example of how to use the Xml class.
<?php
//create Test2 class
class Test2
{
var $_test2var;
var $_test2num;
var $_test2array;
function Test2()
{
$this->_test2var = 'test2';
$this->_test2num = 101;
$this->_test2array = array('food' => 'pizza', 'color' => 'red');
}
}
//create Test class
class Test extends Xml
{
var $_testvar;
var $_testnum;
var $_testarray;
var $_testobject;
function Test()
{
$this->_testvar = 'test';
$this->_testnum = 100;
$this->_testarray = array('one' => 1, 'two' => 2, 'three' => 3);
//hold copy of Test2
$this->_testobject = new Test2();
}
}
//create instance of Test
$test = new Test();
//marshal Test class into xml
//**if Test class did not subclass Xml, use "$xml = Xml::marshal($test);"
$xml = $test->marshal();
//display marshalled Test class
echo '<b>Test class</b><br/><pre>'.Xml::xmlentities($xml).'</pre><hr/>';
$first = Xml::transform($xml, array('first.xsl'));
//display transform with only first.xsl
echo '<b>first.xsl</b><br/><pre>'.Xml::xmlentities($first).'</pre><hr/>';
$second = Xml::transform($xml, array('first.xsl', 'second.xsl'));
//display transform pipeline with first.xsl and second.xsl
echo '<b>second.xsl</b><br/><pre>'.Xml::xmlentities($second).'</pre>';
?>
first.xsl
This stylesheet does the first part of the pipeline transform: xml->xml->html
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html"/>
<xsl:template match="test">
<favorites>
<xsl:for-each select="_testobject/_test2array/value">
<favorite>
<xsl:attribute name="type">
<xsl:value-of select="@key"/>
</xsl:attribute>
<xsl:value-of select="."/>
</favorite>
</xsl:for-each>
</favorites>
</xsl:template>
</xsl:stylesheet>
second.xsl
This stylesheet does the second part of the pipeline transform: xml->xml->html
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html"/>
<xsl:template match="favorites">
<html>
<body>
<p>favorites</p>
<ul>
<xsl:for-each select="favorite">
<li><xsl:value-of select="@type"/>: <xsl:value-of select="."/></li>
</xsl:for-each>
</ul>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
That completes the short example of how to use the Xml class.
