Xmnl tags in flash

HI,

Can someone tell me if there only certain tags in xml that flash recognises, i know this is true with HTML and flash but is it the same in xml? I have an xml file with tags suchs as…‘title’, ‘main’, ‘thumb’. Im trying to add other tags such as ‘description’ but cant get flash to read it, in the text field in flash were the ‘description’ attribute should be i just get an ‘undefined’. Why would this be…
(i’ve included an example of the xml file below)…

in the actionscript the “extText_txt.text = this.description;” is where the description tag from the xml should load…but i cant get it to work…

thanks for any help…
