Customization of RSS items creation inside the XML

PROBLEM:
When a RSS was created inside the channel, the order of creation was not the proper one. The problem arised when an item was created swapping its version from draft to live workspace.

SOLUTION:
We edited the $resItems of the main() function inside the class.tx_push2rss3ds_pi1.php of the push2rss_3ds extension in the following way:

$resItems = $GLOBALS['TYPO3_DB']->exec_SELECTquery( '*',
'tx_push2rss3ds_item',
'NOT deleted AND NOT hidden '.$workspaceLiveCondition.' AND pid="'.$rowChannel['pid'].'"'.$whereClause2,
'', 'tstamp desc');
