File not Found during Collada Export Process about importer-exporter HOT 5 CLOSED

Do you think you can share the CityGML data? This would help us a lot in reproducing and fixing the issue.

Sure no problem, here you can find one smaller dataset with the same problem:

Hi Mechele,

I can reproduce that problem as well. The cause of that problem is that your CityGML files (e.g. CLES_11) contain some invalid GMLIDs like "Unit_106.419/4.1170".
According to the XML/GML Specification, GMLID must start with a letter or underscore, and can only contain letters, digits, underscores, hyphens, and periods.....

It means that the character "/" is not allowed in GMLID.

Solution: The Importer-Exporter Tool provides a functionality for generating globally unique UUIDs and assigning them to all GML objects during the CityGML-Import process. Invalid GMLIDS will be therefore replaced by the newly generated UUID value, and then the Collada-Exporter should work fine.
This functionality can be found under (preferences --> CityGML Import --> gml_id handling --> replace all gml:ids by UUIDs) on importer-exporter-GUI.

Dear Zhihang,

thank you for your reply. I've just tested your solution and it works well, no errors are raised up.

We didn't noticed the "/" character in the ID, now we have to find the problem in our CityGML generation process, but the replace:ids functionality works.

Thank you,
