I would like a universal solution.
There's no universal solution, by definition. The nearest you'll get is something like the PostgreSQL "dollar string": $SomeTag$any text$SomeTag$ You can choose any tag you like for SomeTag and it'll match only the corresponding tag, so this can be nested. But it's long and ugly, especially when you don't need to actually nest it. Python is not a shell scripting language, and trying to treat it as one is usually going to get you into tangles like this. Much better, IMO, is to treat Python as a scripting language, where higher-level constructs like lists are the norm. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
