Creates a new SimpleXMLElement object

Description

final public SimpleXMLElement::__construct ( string $data [, int $options = 0 [, bool $data_is_url = false [, string $ns = "" [, bool $is_prefix = false ]]]] )

Creates a new SimpleXMLElement object.

Parameters

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.

Note:
It may be necessary to pass LIBXML_PARSEHUGE to be able to process deeply nested XML or very large text nodes.
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: Namespace prefix or URI.
is_prefix: TRUE if ns is a prefix, FALSE if it's a URI; defaults to FALSE.

Return Values

Returns a SimpleXMLElement object representing data.

Errors/Exceptions

Produces an E_WARNING error message for each error found in the XML data and additionally throws an Exception if the XML data could not be parsed.

Tip

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

Examples

Note:
Listed examples may include example.php, which refers to the XML string found in the first example of the basic usage guide.

<?php

include 'example.php';

$sxe = new SimpleXMLElement($xmlstr);
