given the following xml (bug_report.xml):
<?xml version="1.0" encoding="utf-8" ?>
<ITEM>
<TEST>1</TEST>
<ABC>0</ABC>
</ITEM>
and the following xsl (bug_report.xsl):
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="text" indent="no"/>
<xsl:param name="TEST"/>
<xsl:param name="ABC"/>
<xsl:template match="/">
<xsl:apply-templates select="ITEM[TEST=$TEST and ABC=$ABC]"/>
</xsl:template>
<xsl:template match="ITEM">
position: <xsl:value-of select="position()"/>
</xsl:template>
</xsl:stylesheet>
and the following php (bug_report.php):
<?php
/*
* this function is the xslt processor
* @param ($xml) string xml text-data
* @param ($xsl) string xsl stylesheet
* @param ($addl_buffers) array additional xml buffers, if any
* @param ($rt_params) array run-time paramaters for the stylesheet, if any. optional.
* @return ($data) xslt translated data
*/
function transform_xslt ($xml = '', $xsl = '', $addl_buffers = '', $rt_params =
array()) {
$args = array( "/_xml" => $xml,
"/_xsl" => $xsl
);
/* add addl buffers here */
/* testng */
if($addl_buffers != '') {
foreach($addl_buffers as $buffer_name => $values) {
$args[$buffer_name] = $values;
}
}
$xh = xslt_create();
$data = xslt_process($xh, "arg:/_xml", "arg:/_xsl", NULL, $args, $rt_params)
or $data = xslt_error($xh).":".xslt_errno($xh);
xslt_free($xh);
return($data);
}
$xml = join('', file("bug_report.xml"));
$xsl = join('', file("bug_report.xsl"));
$params = array("TEST" => 1, "ABC" => 0);
$trans = transform_xslt($xml, $xsl, "", $params);
echo "<pre>\n";
echo $trans;
echo "</pre>\n";
?>
if you inadvertently use:
<xsl:apply-templates match="ITEM[@TEST=$TEST and @ABC=ABC]"/>
on line 10 of bug_report.xsl instead of:
<xsl:apply-templates match="ITEM[TEST=$TEST and ABC=$ABC]"/>
