"One way would be to look for uppercase lowercase combinations inside a word boundary, but not (only) at the beginning. This isn't a combination you see in 'normal' words so it could work. \n\nSo something like \\s[^ ]+[A-Z][a-z].+\\s\n\nYou'll probably need to tune the boundaries, as now it just looks for combis devided by spaces. "
