Kotlin Solution

Kotlin has a built-in function for this, removeSuffix (Documentation)

var text = "filename.xml"
text = text.removeSuffix(".xml") // "filename"

If the suffix does not exist in the string, it just returns the original

var text = "not_a_filename"
text = text.removeSuffix(".xml") // "not_a_filename"
