TYPO3 Core

please provide steps to reproduce the issue including example svg file.
Thanks!

Unfortunately I can not provide the full svg because it is from client project which is not yet online.

The problem is, that simplexml_load_string throws a warning if the namespaces are not correct. This should simply be ignored.
It is not the responsibilty of TYPO3 to log/show any error within an uploaded svg image (external resource).

Here just the relevant part:

Hi All,

I can able to reproduce the same issue with TYPO3 9.5.13 version. Could you please have a look on this? Because of this, the filelist module is broken. Thank you.
