Honestly, if you just need a one-off transformer, VB.Net is probably one of the better options. The .Net XML library is pretty good in the box, and VB.Net has XML literal support on the top... if you just need to read, then C# is a better language imo.
VB.NET is masochism, and XML literals are a dumb, confusing, and unnecessary feature. Creating XML elements with regular code is quite easy, and at scale, you probably want templates.
