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).
xhXSLT 处理器连接标识符，由 xslt_create() 创建。
handler
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:
$xh
, int $error_level
, int $error_code
, array $messages
)没有返回值。
Example #1 xslt_set_error_handler() Example
<?php
// Our XSLT error handler
function xslt_error_handler($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));
?>
以上例程的输出类似于：
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"
}
}

Addition to the last note. in the array I have used array($this, "myMethod") to make it use an internal function in a class.
I reckon this is how it is meant to work (not tested)
$myObj = new MyObj()
xslt_set_error_handler_($xh, array($myObj, "myErrorMethod"));

To set the error handler to the instance of an object, use the:
xslt_set_error_handler($xh, array($obj, $method))
syntax.
