SimpleXMLElement::__construct
Creates a new SimpleXMLElement object
Description
public SimpleXMLElement::__construct(
string $data,
int $options = 0,
bool $dataIsURL = false,
string $namespaceOrPrefix = "",
bool $isPrefix = false
)
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.
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.
