design question for pushing DOM/XML to client, then display

[Yasushi Okubo]

Hi, experts

I have a design question for how to push/display DOM/XML page on 
client.  There is a table data stored in an array that is displayed with 
datascroller.  I want to add a function to export  this data  in xml 
format on client.
I  am thinking to convert an array to DOM  then use  write function to 
covert it to XML file. 
Could someone advise me the best way to display this xml file on the 
client side without writing it as a file in the directory on the server 
?  It sounds ajax can to it easily, but do not know how to do yet.

Thanks,
yasushi
