范例

例子 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";
}

?>

上例将输出:

<titles>PHP: Behind the Parser</title>
