I don't feel real strongly about it either but don't want to add a lot of
new methods to Element that probably don't belong there.  getChildText() was
added/kept for a common use case involving web.xml files I think.  Hmmm, who
might have wanted that?

In the signatures where I first put my 2 cents in, I was just trying to
offer a way to cover the null pointer problem with getChild().  Something
like

String text = Helper.getText(yourElement.getChild("name")) //return the text
or ""
String text = Helper.getTextTrim(yourElement.getChild("name")) 
String text = Helper.getTextNormalized(yourElement.getChild("name"))

You get the idea.  These are a little shorter than the other helper ideas
presented so far and do pretty much the same thing.
