very nice patch. Thank you. Ill send me code comments a bit later for you to adjust and we are ready to land

[Noneatme]

Alright! Thanks!

Sorry, it took me longer :) Patch looks great except couple issues:

1. default settings validation: You can create an array of default values and then do an array_merge with settings passed into the function.
2. revert if(file_exists($importFile)) to an early return to streamline the code.

if (!file_exists) {
     throw exception
     return
}

        if($result) {
                $success = true;
            }
            // Something went wrong
            else {
                $success = false; 
            }

this is the same as return (bool)$result;

1. rename loadXML -> loadXml for a naming consistency.

as well i think it doesnt make sense to add escapeQuery parameter as most of escaped sql queries will fail. You need to escape variables, not SQL query itself.
So you can remove that.

I fixed the issues you you mentioned. Thanks!
But now, the tests fail somehow (data doesn't get inserted). I have to take a deeper look. Don't merge right now, I will push a commit later when I found the issue.

It should work now. The .csv test file was not in dos mode so the \r\n selector failed.
