Import-Export and Plot-SVG files

Hey guys I was trying to use the function on the following link to import, export and plot a file with svg format: https://de.mathworks.com/matlabcentral/fileexchange/66554-svg-import-export . The 'example' in the link worked with the the file 'building.svg', but it doesn't work when I try to load my own file. Can someone help me with that please?... Here is the error code:

>> example
Dot indexing is not supported for variables of this type.

Error in loadSVG (line 43)
    image.x=str2num(char(item.getAttribute('x')));

Error in example (line 1)
svg=loadSVG('einstufigesZR.svg');
 
>> 

and attached is my own simple file as an example.

Thanks guys for the help.
