Read in XMLdig Waveform

Hey, I want to read in a waveform to MatLab which has the XMLDig-format. The waveform was recorded with a Lecroy Oscilloscope. I am able to read the data into Matlab and encode it (base64 encoding).

fseek(fid, 1387, 'bof'); %beginning of binary data
decimal=fread(fid,4192906,'schar');  %size of data
STR = string(decimal);
txt = (char((decimal)));
decoded = (matlab.net.base64decode(txt));
decodedbin = dec2bin(decoded,8); %convert to bin with 8 digits

This code works for my file, but i dont know how to intepret the data. If someone has had the same problem and was able to solve it and plot the waveform right i would be very thankful for help.

Unfortunately the documentation of the file format is only available to registered Lecroy customers.

@Walter Roberson there are only these two explanations in the documentation file.

The only way I can see what is described working is if there is information in the header before the base64 information that tells you which array is encoded and what the expected sizes are. If there is, I think it might be possible to decode into arrays. However according to the documentation, the data arrays have to be analyzed to produce waveforms; the process of doing that is not clear from the description.
