(PHP 5, PHP 7)
SimpleXMLElement::__construct — Creates a new SimpleXMLElement object
$data [, int $options = 0 [, bool $data_is_url = false [, string $ns = "" [, bool $is_prefix = false ]]]] )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, which affect reading of XML documents. Options which affect the output of XML documents (e.g. LIBXML_NOEMPTYTAG) are silently ignored.
Note:
It may be necessary to pass
LIBXML_PARSEHUGEto 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.
Returns a SimpleXMLElement object representing data.
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.
Use libxml_use_internal_errors() to suppress all XML errors, and libxml_get_errors() to iterate over them afterwards.
