Retrieve array of errors.
Returns an array with LibXMLError objects if there are any errors in the buffer, or an empty array otherwise.
Example #1 A libxml_get_errors() example
This example demonstrates how to build a simple libxml error handler.
<?php
libxml_use_internal_errors ( true );
$xmlstr = <<< XML
<?xml version='1.0' standalone='yes'?>
<movies>
<movie>
<titles>PHP: Behind the Parser</title>
</movie>
</movies>
XML;
$doc = simplexml_load_string ( $xmlstr );
$xml = explode ( "\n" , $xmlstr );
if (! $doc ) {
$errors = libxml_get_errors ();
foreach ( $errors as $error ) {
echo display_xml_error ( $error , $xml );
}
libxml_clear_errors ();
}
function display_xml_error ( $error , $xml )
{
$return = $xml [ $error -> line - 1 ] . "\n" ;
$return .= str_repeat ( '-' , $error -> column ) . "^\n" ;
switch ( $error -> level ) {
case LIBXML_ERR_WARNING :
$return .= "Warning $error -> code : " ;
break;
case LIBXML_ERR_ERROR :
$return .= "Error $error -> code : " ;
break;
case LIBXML_ERR_FATAL :
$return .= "Fatal Error $error -> code : " ;
break;
}
$return .= trim ( $error -> message ) .
"\n Line: $error -> line " .
"\n Column: $error -> column " ;
if ( $error -> file ) {
$return .= "\n File: $error -> file " ;
}
return " $return \n\n--------------------------------------------\n\n" ;
}
?>
以上例程会输出:
<titles>PHP: Behind the Parser</title> ----------------------------------------------^ Fatal Error 76: Opening and ending tag mismatch: titles line 4 and title Line: 4 Column: 46--------------------------------------------
