@Thomas Zecha I've put the xml stuff on hold since we last spoke to avoid duplicating efforts. My intention was to jump back in when your development was more advanced, to help with testing and adding components and stuff. I haven't tested what Vadim has done in this branch. I think I will have a look at it sooner or later, but for the moment I have been concentrating my efforts on other aspects of qucs-s development. If you have time to work on the netlisting stuff, go ahead. No worries :-)
