After upgrade PHP from 4.2.3 into 4.3.2 xslt transformation stop working.

1.php (not working)
<? 

// Allocate a new XSLT processor 
$xh = xslt_create() or die('Can not do; xslt_create()'); 

$arguments = array( 
    '/_xml' => file_get_contents('xml/1.xml'), 
    '/_xsl' => file_get_contents('xsl/1.xsl'), 
); 

// Process the document 
if ( $result = xslt_process($xh, 'arg:/_xml', 'arg:/_xsl', NULL, $arguments) ) { 
    print "SUCCESS, test.xml was transformed by test.xsl into result.xml"; 
    print ", result.xml has the following contents\n<br>\n"; 
    print "<pre>\n"; 
    echo $result; 
    print "</pre>\n"; 
} 
else { 
    print "Sorry, test.xml could not be transformed by test.xsl into"; 
    print "  result.xml the reason is that " . xslt_error($xh) . " and the "; 
    print "error code is " . xslt_errno($xh); 
} 

xslt_free($xh); 
?> 

2.php - working
<?

$arguments = array(

// Process the document 
if ( $result = xslt_process($xh, 'arg:/_xml', 'xsl/1.xsl', NULL, $arguments) ) {

    print "<pre>\n"; 
    echo $result; 
    print "</pre>\n"; 
} 
else { 
    print "Sorry, test.xml could not be transformed by test.xsl into"; 
    print "  result.xml the reason is that " . xslt_error($xh) . " and the ";
