if you mean a moongate, then you can take a look at this example as well
http://xmlspawner.15.forumer.com/index.php...123&hl=moongate
If you want to specify an xmldialog Action that will create a temporary moongate to some location you can use something like this
moongate/location/(1200,300,16)/target/(1500,1100,0)/targetmap/felucca/ATTACH/temporaryquestobject,,5which will create a moongate at location 1200,300,16 which will transport players to target location 1500,1100,0 and will delete itself after 5 minutes
