Issue in the conversion of EBUTTXML2STL format

[jayotirana]

I have an xml file and converting the same to stl format, some information is missing in the stl output file using the conversion end point: EBU-TT → STL Sample xml File:

Or use this file for conversion: https://bbc.github.io/subtitle-guidelines/sample-ebutt-prepared.html

some information is missing in the stl output file

Hmm, could you please specify which information exactly you miss in the conversion result?

[jayotirana]

..and they all lived happily ever after.</tt:span> </tt:p> Xml File: STL File:

Xml file has four blocks and in the STL file only 3 blocks loaded and the third one also not in the correct format.

Ah, I see; there is indeed an issue in this conversion path. Note that the involved module EBU-TT2STLXML is still in beta state. Nevertheless this is an issue that will be fixed soon. Thanks for raising this!
