I´m thinking in a way to integrate flash and dbmansql

I have an flash file that reads an html file to show real state details
where it can find some information like type, value, image

--- the html ---
image1=images/imovel_flash1.jpg&title1=<b>Casa Residencial // Ref: 106VE</b>&content1=Santa Mena - Guarulhos<br>3 dormitórios ( 1 suíte )<br>3 wcs<br>5 vagas<br>terreno: 1000mts
--- end html ---

when I want to update the listing it´s just update the html

Now I want to make a query and save it as a txt, html or maybe xml, but I need some directions on how to make xml_feed work or have any other way to make this file ?

please somebody give me any directions with xml

Thanks
