No, but I can simplify your code in a couple of ways.

Don't know why you're storing this result, only to fetch it in the
next line. Why not just replace the two lines above with:
Iterator e = r.runQuery("elementSearch", new ValueVector());
...

Not sure why you're using the variable "n". What's wrong with just
doing this:
number = r.executeCommand("(count-query-results childElementCount)").intValue(null);
