[wp-hackers] WordPress Transients API

[Pete Mall]

There is indeed a problem with SimpleXML serialization... I was able to work
around it by serializing the SimpleXML object before set_transient and using
the following code after get_transient:

unserialize( str_replace( array( 'O:16:"SimpleXMLElement":0:{}',
'O:16:"SimpleXMLElement":' ), array( 's:0:"";', 'O:8:"stdClass":' ), $str )
);
