Auth_Yadis_dom::content

(

$node

)

Return the textual content of a specified node.

Parameters

mixed

$node

A node object from a previous call to $this->evalXPath().

Returns

string $content The content of this node.

    {
        if ($node) {
            return $node->textContent;
        }
    }

& Auth_Yadis_dom::evalXPath	(		$xpath,
			$node = null
	)

Evaluate an XPath expression and return the resulting node list.

This should be overridden by subclasses.

Parameters

string	$xpath	The XPath expression to be evaluated.
mixed	$node	A node object resulting from a previous evalXPath call. This node, if specified, provides the context for the evaluation of this xpath expression.

Returns

array $node_list An array of matching opaque node objects to be used with other methods of this parser class.

Auth_Yadis_dom::registerNamespace	(		$prefix,
			$uri
	)

Register a namespace with the XML parser.

This should be overridden by subclasses.

Parameters

string	$prefix	The namespace prefix to appear in XML tag names.
string	$uri	The namespace URI to be used to identify the namespace in the XML.

Returns

boolean $result True if the registration succeeded; false otherwise.

Auth_Yadis_dom::setXML

(

$xml_string

)

Set this parser object's XML payload.

This should be overridden by subclasses.

Parameters

string

$xml_string

The XML string to pass to this object's XML parser.

Returns

boolean $result True if the initialization succeeded; false otherwise.
