Does anyone here know an other workaround? Thanks in advance!

You need to watch where line breaks go in source posts to Usenet. You got a
stray greater-than character ('>', a.k.a., "right angle bracket") that
belonged with the xml PI, but was somehow moved to a different line.

Also, the variable "XMLString", being a variable, should start with a
lower-case letter, by convention.

public class Questionmark_TEST{
public Questionmark_TEST(){}

public static void main(String [] args){
String XMLString =
"<?xml version=\"1.0\" encoding=\"UTF-8\"?>"

    "<categories><NodeOne action='Print?'/></categories>";

    String OldNode = "<NodeOne action='Print?'/>";
    String NewNode = "<NodeOne action='Print?'>empty</NodeOne>";

    XMLString = XMLString.replaceAll(OldNode,NewNode);
    System.out.println("new XMLString : "+XMLString.toString());
}
}

Did you read the Javadocs on the replaceAll() method?
<http://java.sun.com/javase/6/docs/api/java/lang/String.html#replaceAll(java.lang.String,%20java.lang.String)>

The first argument is a regular expression, in which the question mark has
special significance.
