Phill addressed this problem in his implementation a few emails back.

Essentially, his getXXX methods also take a default value that it returns in
the case where it fails...


getInt(String name, int default) {
int result;
try{
  result = Integer.parseInt(getChildTextTrim(name));
}
catch(Exception ex){
  result = default;
}
return result;
}
