XSL error handling in PHP5

[al3x4nder@gmail.com]

I`m need hanling XSLT errors in my script,
before I`m use Sablotron, that has nice
interface for it:
------------8<------------------
function ProduceXHTML($x ml, $xsl){
$xh = xslt_create();
xslt_set_encodi ng ($xh, CODE_PAGE);
$arguments = array('/_xml' => $xml, '/_xsl' => $xsl);
$result = @xslt_process($ xh, 'arg:/_xml', 'arg:/_xsl', NULL,
$arguments);
$this->error = (int)xslt_errno ($xh);
if($this->error){
$errorMessage = sprintf("Cannot process XSLT document
[code %d]: %s",
xslt_errno($xh) , xslt_error($xh) );
$this->AddErrorMessag e(5, $errorMessage);
}

xslt_free($xh);
}

------------8<------------------

but now I`m ported my project
in PHP5 and use XSLlib like this:

------------8<------------------
function ProduceXHTML($x sltemplate){
$xh = new XSLTProcessor() ;
$xml = new DOMDocument();
$xsl = new DOMDocument();

$xsl->loadXML($thi s->LoadXSLT(TEMPL ATES_ROOT.$xslt emplate));
$xml->loadXML($thi s->xml);

$xh->importStyleShe et($xsl);
$xhtml=$xh->transformToXML ($xml);

if($this->IsDebug()){
header('Content-type: text/xml');
die($this->xml);
}
if ($xhtml) {
$xhtml = str_replace("&a mp;", "&", $xhtml);
echo $xhtml;
} else {
/* commented, because PHPv5 used
printf("Cannot process XSLT document [code %d]: %s",
xslt_errno($xh) , xslt_error($xh) );
*/
return false; // invalid XSL
}
unset($xh);

}
------------8<------------------
anybody know how I can track errors now?

thanks and sorry for my English

Re: XSL error handling in PHP5

I solved this problem years ago:

1) Have a standard error handler which can be invoked using trigger_error() ;
I call mine 'errorHandler'.

2) Create an alternative error handler for XML/XSL processing in PHP 5. I
call mine 'XML_errorHandl er'

function XML_errorHandle r ($errno, $errstr, $errfile, $errline,
$errcontext)
// deal with errors from XML or XSL functions.
{
// pass these details to the standard error handler
errorHandler (E_USER_ERROR, $errstr, $errfile, $errline,
$errcontext);
} // XML_errorHandle r

3) Just before performing and XML/XSL processing switch to the alternative
error handler:

set_error_handl er('XML_errorHa ndler');

4) Don't forget to switch back again afterwards:

set_error_handl er('errorHandle r');

All this code can be downloaded from my website in my sample application at
