Returns an object of class SimpleXMLElement with properties containing the data held within the XML document. On errors, it will return FALSE.

Front 3

simplexml_load_string

Back 3

Takes a well-formed XML string and returns it as an object.


( string $data [, string $class_name = "SimpleXMLElement" [, int $options = 0 [, string $ns [, bool $is_prefix = false ]]]] )


Returns an object of class SimpleXMLElement with properties containing the data held within the xml document. On errors, it will return FALSE.

Front 4

SimpleXMLElement::addAttribute

Back 4

Adds an attribute to the SimpleXML element.


( string $name , string $value [, string $namespace ] )


No value is returned.

Front 5

SimpleXMLElement::addChild

Back 5

Adds a child element to the node and returns a SimpleXMLElement of the child.


( string $name [, string $value [, string $namespace ]] )


The addChild method returns a SimpleXMLElement object representing the child added to the XML node.

Front 6

SimpleXMLElement::asXML

Back 6

The asXML method formats the parent object's data in XML version 1.0.


([ string $filename ] )


If the filename isn't specified, this function returns a string on success and FALSE on error. If the parameter is specified, it returns TRUE if the file was written successfully and FALSE otherwise.

This method finds the children of the element of which it is a member. The result follows normal iteration rules.


([ string $ns [, bool $is_prefix ]] )

Front 9

SimpleXMLElement::__construct

Creates a new SimpleXMLElement object.


( string $data [, int $options [, bool $data_is_url [, string $ns [, bool $is_prefix ]]]] )


Returns a SimpleXMLElement object representing data .

Front 10

SimpleXMLElement::getDocNamespaces

Back 10

Returns namespaces declared in document


([ bool $recursive ] )


The getDocNamespaces method returns an array of namespace names with their associated URIs.

Creates a prefix/ns context for the next XPath query. In particular, this is helpful if the provider of the given XML document alters the namespace prefixes. registerXPathNamespace will create a prefix for the associated namespace, allowing one to access nodes in that namespace without the need to change code to allow for the new prefixes dictated by the provider.


( string $prefix , string $ns )


Returns TRUE on success or FALSE on failure.

Front 14
