Cms, links inside flash movie

I’m using a dynamic textfield that loads text from an xml-file.
The xml-file gets its content out of a mysql database. So then I let my client update the texts in the database through some kind of CMS (php).

Now I have this particular problem.

I want my client to be able to insert a link in the xml file through the CMS. Ultimately, when the user clicks that link, another swf gets loaded in a MC somewhere in the movie.

E.g. The client types:
You can view a picture here and here.

When the user clicks on of these links, an swf with the picture gets loaded in a MC somewhere in the same movie.

Is something like that possible?
