Creates a new SimpleXMLElement object

Description

public SimpleXMLElement::__construct(
    string $data,
    int $options = 0,
    bool $dataIsURL = false,
    string $namespaceOrPrefix = "",
    bool $isPrefix = false
)

Creates a new SimpleXMLElement object.

Parameters

data: A well-formed XML string or the path or URL to an XML document if dataIsURL 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_PARSEHUGE to be able to process deeply nested XML or very large text nodes.
dataIsURL: By default, dataIsURL is false. Use true to specify that data is a path or URL to an XML document instead of string data.
namespaceOrPrefix: Namespace prefix or URI.
isPrefix: true if namespaceOrPrefix 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.
