SimpleXMLElement::__construct

(PHP 5 >= 5.0.1)

SimpleXMLElement::__construct — Creates a new SimpleXMLElement object

__construct ( string $data [, int $options [, bool $data_is_url [, string $ns [, bool $is_prefix ]]]] )

Creates a new SimpleXMLElement object.

data: A well-formed XML string or the path or URL to an XML document if data_is_url is TRUE.
options: Optionally used to specify additional Libxml parameters.
data_is_url: By default, data_is_url is FALSE. Use TRUE to specify that data is a path or URL to an XML document instead of string data.
ns
is_prefix

Returns a SimpleXMLElement object representing data.

Produces an E_WARNING error message for each error found in the XML data and throws an exception if errors were detected.

Tipp

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

Beispiel #1 Create a SimpleXMLElement object

<?php
include 'example.php';
$sxe = new SimpleXMLElement($xmlstr);
echo $sxe->movie[0]->title;

?>

Beispiel #2 Create a SimpleXMLElement object from a URL

<?php
$sxe = new SimpleXMLElement('http://example.org/document.xml', NULL, TRUE);
echo $sxe->asXML();

?>

simplexml_load_string() – Übersetzt einen XML-String in ein Objekt
simplexml_load_file() – Übersetzt ein XML-File in ein Objekt
Behandlung von XML-Fehlern
libxml_use_internal_errors() – Disable libxml errors and allow user to fetch error information as needed
