OK, that's why I asked "Do they have a suffix...", I meant the orphan
ones.

So you'll have to write a simple (bash?) script that uses find (as
above) to find all the xmp files and then removes only the orphans.

The logic would be something like:-

    find an .xmp file
    strip off the .xmp (use basename)
    find the 'parent' file (the one with the .xmp removed)
    if the above fails then remove the .xmp file
