Passing XML values from one swf to another?

hi,

i’m pretty new to xml and actionscripting, so i’m dealing with the following problem :

i’m creating a flash database where students in architecture will be able to click in a row/column matrix to define a theme. following to that action, the right data needs to be loaded from an xml file into a new swf, that loads over the base swf with a LoadMovieNum function.

i’ve put all the data in one xml, and the first base swf needs to examine what part of that xml to load into the second swf.

:q: how do i pass the values (according to the right theme) from the base swf to the 2nd swf that i’m loading, so that tha last one can show the right text values?
