Elenco dei parametri

data

A well-formed XML string

class_name

You may use this optional parameter so that simplexml_load_string() will return an object of the specified class. That class should extend the SimpleXMLElement class.

options

Since PHP 5.1.0 and Libxml 2.6.0, you may also use the options parameter to specify additional Libxml parameters.

ns

Namespace prefix or URI.

is_prefix

TRUE if ns is a prefix, FALSE if it's a URI; defaults to FALSE.

Valori restituiti

Returns an object of class SimpleXMLElement with properties containing the data held within the xml document, o FALSE in caso di fallimento.

Errori/Eccezioni

Produces an E_WARNING error message for each error found in the XML data.

Suggerimento

Use libxml_use_internal_errors() to suppress all XML errors, and libxml_get_errors() to iterate over them afterwards.

Esempi

Example #1 Interpret an XML string

<?php
$string 
= <<<XML
<?xml version='1.0'?> 
<document>
 <title>Forty What?</title>
 <from>Joe</from>
 <to>Jane</to>
 <body>
  I know that's the answer -- but what's the question?
 </body>
</document>
XML;

$xml simplexml_load_string($string);

print_r($xml);
?>

Il precedente esempio visualizzerĂ :

SimpleXMLElement Object
(
  [title] => Forty What?
  [from] => Joe
  [to] => Jane
  [body] =>
   I know that's the answer -- but what's the question?
)

At this point, you can go about using $xml->body and such.
