Hi Klaus,
thanks for answer.
It's a huge tour consisting of single panoramas only, where the '.' could be handled using filterbasename.
All the pano-xml is generated dynamically using a json file with all it's benefits - and it was working fine.
I never paid much attention to the fact that single panos omit the scene-tag etc. - single panos and vtours where always separated and for the latter there is the comfortable tour-editor so that you don't look at the xml-output very often.
Unfortunately I ran into the situation where I wanted to attach a vtour, ignoring the differences in the details ("I can wrap the single <image> tags as scenes on my own - it' easy as pie..." )
But yeah, you adapt one thing only to face the next problem...
Meanwhile I came to the conclusion that there is no "easy way out" (it should have been in the concept from the beginning), and your answer confirms me that this would be an everlasting source of ugly patchworking and headache.
So the best solution is simply omitting the periods and to re-generate the single-panos to single-scene-vtours so that in the end all pathes, the xml-structure, name-handling etc. is always the same.
It's some work to do, but finally there will be "Ruhe im Karton"
thx
