xslt_set_error_handler — Set an error handler for a XSLT processor
Set an error handler function for the XSLT processor given by xh , this function will be called whenever an error occurs in the XSLT transformation (this function is also called for notices).
The XSLT processor link identifier, created with xslt_create().
The user function needs to accept four parameters: the XSLT processor, the error level, the error code and an array of messages. The function can be shown as:
No value is returned.
Example#1 xslt_set_error_handler() Example
<?php
// Our XSLT error handler
function xslt_error_handler($handler, $errno, $level, $info)
{
// for now, let's just see the arguments
var_dump(func_get_args());
}
// XML content :
$xml='<?xml version="1.0"?>
<para>
oops, I misspelled the closing tag
</pata>';
// XSL content :
$xsl='<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<strong><xsl:value-of select="para"/></strong>
</xsl:template>
</xsl:stylesheet>';
$xh = xslt_create();
xslt_set_error_handler($xh, "xslt_error_handler");
echo xslt_process($xh, 'arg:/_xml', 'arg:/_xsl',
NULL, array("/_xml" => $xml, "/_xsl" => $xsl));
?>
The above example will output something similar to:
array(4) {
[0]=>
resource(1) of type (XSLT Processor)
[1]=>
int(3)
[2]=>
int(0)
[3]=>
array(6) {
["msgtype"]=>
string(5) "error"
["code"]=>
string(1) "2"
["module"]=>
string(9) "Sablotron"
["URI"]=>
string(9) "arg:/_xml"
["line"]=>
string(1) "4"
["msg"]=>
string(34) "XML parser error 7: mismatched tag"
}
