PHP8.1 xml output supprt

[wouter-toppy]

Almost simular to #2856

except, its not possible to pass a argument to the function anymore.

Uncaught RuntimeException: PHP Error: DOMDocument::createTextNode(): Passing null to parameter #1 ($data) of type string is deprecated in /app/vendor/openlss/lib-array2xml/LSS/Array2XML.php:174 in /app/vendor/vimeo/psalm/src/Psalm/Internal/ErrorHandler.php:66

Bug is not directly fixable in psalm. but needs to be fixed in the lib-array2-xml bundle.
Reported a issue there, which needs to be fixed and tagged.

if so. than psalm need to require expliceit that version (or higher)

nullivex/lib-array2xml#21

Hey @wouter-toppy, can you reproduce the issue on https://psalm.dev ?

Ran into this as well. Psalm v4.30.0 on PHP 8.1.10.

The lib-array2xml repo has not had any updates in over three years. It could be abandoned. Fork?

The workaround is incredibly simple, albeit gruesome. Apply the fix from this PR nullivex/lib-array2xml#19 to the file in the vendor directory.

While normally modifying vendor files is a huge no-no for me, since I just need this for a one-off on my local machine it's fine for me, just beware.
