Examples

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 === false) {
    
$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";
}

?>

The above example will output:

  <titles>PHP: Behind the Parser</title>
----------------------------------------------^
Fatal Error 76: Opening and ending tag mismatch: titles line 4 and title
  Line: 4
  Column: 46

--------------------------------------------

Please beware that the column property seems almost always to be invalid. I thought it only occurred when the line in question was long (and I was just about to submit a bug report with an example), however, at the time of posting, you can even see the problem in the example provided on this page: line 4 does not even have 46 characters. Where the XML line is long, the difference can be very large.

This property comes from the libxml extension, so in any case I don't think this is a PHP bug, however it is worth knowing that the value might be totally unreliable to save some confusion.

The PHP documentation page for the libXMLError class gives some indication, stating:

"This property isn't entirely implemented in libxml and therefore 0 is often returned."

(My libxml version: 2.9.1)
