Usage Example
|
XML_Array -- Convert XML to Associative Array
Usage: $xml = new XML_Array(xmldata(string),ignorefields(array 1,2,3),replacefields(array OLD => NEW),show attributes?,convert to upper)
$array = $xml->ReturnArray();
Example: $xml = new XML_Array('http://www.slashdot.org/slashdot.xml',array('backslash'),array('story' => '_array_'),true,false);
print_r($xml->ReturnArray());
print_r($xml->ReturnReplaced());
print_r($xml->ReturnAttributes());
Array_XML -- Convert Associative Array to XML
Usage: $array = new Array_XML($xml->ReturnArray(),$xml->ReturnReplaced(),$xml->ReturnAttributes())
$xml = $array->Return();
