getChild() may return null in which case your first example would throw
a NullPointerException.  getChildTextTrim() knows enough to not throw an
exception.  A fair comparison is:

  return e.getChildTextTrim("c");


  Element e = getChild("c");
  if (e != null) {
    return e.getTextTrim();
  else {
    return "";
