从大型XML文件中删除不可打印和/或Unicode字符

Question

I have a method which receives a File object, containing XML-data. Files can be over 50 MB. Is there a convenient way to remove control chars and/or non-printable chars from it.

For smaller files I read the File contents to String and use replaceAll("\\p{Cntrl}", "").
