Al, I have looked at all my XDAs and each has a .wix Import and Export.
As Xara uses this format for testing (probably), it is what I expected.

Code:

I have a large site in German that unpacks into 15MB as a WIX.
I searched for "angegangen" ['approached'] from the open design file in the phrase "und tiefgründig angegangen um das Beste von " in a text editor and found a WIX line:
{2201,246,WCS("und altersbedigten Ver"),W(228),WCS("nderungen die ver"),W(228),WCS("nderte "),W(228),WCS("usserliche "),W(196),WCS("sthetik kunstvoll und tiefgr"),W(252),WCS("ndig angegangen um das Beste von "),WCS(" von")}
What is clear is the fragmentation and the lack of context, which would require a lot of back-tracking to determine where and what in the design the WIX code referred to.
You would then need a click-link to open the XDA with that WIX in the right place.

Clearly, just bite the bullet and export as PDF and use that or as a Vertical Supersite Export and the browser's Find function.

No, I have been waiting for the always-promised/never-delivered API for SmartShapes before looking at the possibilities.

On my Acorn Archimedes, I have a program in BBC Basic that allows coding to generate AFF and DRW files that can be imported into an XDA.
It is probably easier to address such things now as SVGs.
