Creates a new SimpleXMLElement object.

Parâmetros

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

Namespace prefix or URI.

is_prefix

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

Valor Retornado

Returns a SimpleXMLElement object representing data.

Erros

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.
