Yep, now it finally works. Certainly it requires a few more lines. I was going to rewrite some TikZ code which was too dependent on LaTeX and xstring was the last stone on the shoe. Thank you a lot, Phelype and Wolfgang (I didn't know about push/popmacro either and now it's in my to-do readings). Just wondering ... are there specific low level hel;pers (wrt strings)
