Dealing with XML errors when loading documents is a very simple task. Using the libxml functionality it is possible to suppress all XML errors when loading the document and then iterate over the errors.
The libXMLError object, returned by libxml_get_errors(), contains several properties including the message, line and column (position) of the error.
示例 #1 Loading broken XML string
<?php
libxml_use_internal_errors(true);
$sxe = simplexml_load_string("<?xml version='1.0'><broken><xml></broken>");
if ($sxe === false) {
echo "Failed loading XML\n";
foreach(libxml_get_errors() as $error) {
echo "\t", $error->message;
}
}
?>
以上例程会输出：
Failed loading XML
Blank needed here
parsing XML declaration: '?>' expected
Opening and ending tag mismatch: xml line 1 and broken
Premature end of data in tag broken line 1
