Tried to uninstall all xmlsitemap modules and got this errors:

Now - what the heck is now cluttered in the database?

What did you uninstall? All the modules? If so, it is the core bug where module with dependencies aren't properly installed in reverse order.

I have disabled all submodules first, than disabled the xmlsitemap module and then uninstalled all xmlsitemap modules at once.

The error messages doesn't sounds like a dependency issue. More like bugs in the syntax of the SQL statements!

You have to uninstall the sub-modules first as well, then uninstall the primary module. Read #705226-6: Uninstallation Issue as this has come up before and it should be documented in the README.txt.

The good news is there shouldn't really be much messed up in the database. There might be a few stragglers in {variables} which you can find with name LIKE 'xmlsitemap_%'.

Great, by design broken. I still do not understand how this can cause MySQL errors with placeholders and wrong syntax!??? How about making sure required functions (if this is the reason) are available in all submodules!? It may create duplicate code, but it would be a workaround.

The reason is the {xmlsitemap} table gets uninstalled first before the sub-modules try to delete their data from the table, hence the APIs no longer know which placeholders to use since there is no schema data. I've liked to the comment that contained the link to the issue where you can help to fix this bug in core: #151452: Uninstalling modules does not follow dependencies and can lead to WSOD.

And while I realize that you're upset at a module for not working around a serious bug that desperately needs to be addressed in core, I've implemented a temporary fix that should prevent the errors on uninstall.

This looks like a reasonable and easy workaround. Thx.
