Export audio to third party audio editor

I searched through the archives to try to find any pertinent articles about this, but all I could find were articles posted back in 2012 shortly after FCP-X was first introduced. I know back then, Apple had pretty much stripped out of FCP all the export capabilities that were in FCP 7 for the purpose of exporting tracks so they could be brought over to a third party audio editor (like Pro Tools or Adobe Audition) for audio sweetening.

Now, I suspect this functionality is back in FCP-X in the form of the Export > XML option in the File menu.

But I wonder if anyone familiar with this operation could step me through it. I'm wanting to bring the discreet tracks (i.e., "attached storylines") inside FCP-X into a third party audio editor. I typically use Pro Tools for work like this. But I'm also asking for a friend, and he uses Adobe Audition. Neither one of us is a fan of Logic Pro. (I have it, but my eyes glaze over every time I try to make sense of it.)

Anyone here know how this is achieved when going to either Pro Tools or Adobe Audition?

Thanks in advance.
