Web Spider & Search Engine.



xslt_openlog — Directs Sablotron errors to a log file.


boolean xslt_openlog(xslt_handle, filename, log_level);
resource xslt_handle: Handle to a Sablotron parser
string filename: Filename of the log file to use
int log_level: Desired logging level


TRUE on success, FALSE on failure.


Use this function to direct any Sablotron-generated error messages for the given parser handle to the log file named by filename . As of Sablotron version 0.44, the log_level parameter is not used. If the log file does not exist, it will be created; however, as always you must ensure that PHP has permission to write to the directory in which you decide to place the log file.


Example 1141. Opening a log file for a Sablotron parser


/* Intentionally introduce an extra space into file name. */
$xml_file = 'slash dot.xml';
$xsl_file = 'slashdot.xsl';

$xslt = xslt_create();
if (!xslt_openlog($xslt, '/tmp/sablot.log')) {
    echo "Failed to set up log file.\n";
if (!xslt_run($xslt, $xsl_file, $xml_file)) {
    echo "xslt_run() failed\n";
} else {
    echo xslt_fetch_result($xslt);
