My data is in the form of XML files, which I would like to evaluate with MATLAB R2021a. The sizes of the single files are up to 60GB. Using

readstruct('Case1.res', "FileType", "xml");

I can import these files into MATLAB.

Unfortunately, if the input file is greater than 2GB MATLAB reports the file to be faulty. Is there a way to resolve this issue?

Answer 1

As of MATLAB R2021a, this is currently not possible using 'readstruct' or 'readtable'.

However, if you are using MATLAB R2021a, you can use the MATLAB API for XML Processing (MAXP). Here's a doc link:

Note that this will require some more code to work with than 'readstruct', but there is no 2GB limit.
