I still can't find any indication that Qt XML is deprecated. Why do people 
believe that? It says:

But this is just a symptom of DOM. Elsewhere the documentation says:

If Qt XML really becomes deprecated one day, I can just use another DOM 
implementation without changing my algorithms. :)

So, as long as my code is not finished and shows performance problems, I will 
use QDomDocument.

My project is written in C++, and needs to interface this functionality. So, a 
library with a C++ interface would be convenient.

Transforming the SVG file with XSLT to a list of text occurences sounds like a 
good idea.
