getElementByElementName() similar to getElementByClassName() ?

[pstein]

Whenever I want to add something at the end inside an (the first) element which is identifiable by class name I can write:

var div = document.getElementsByClassName("myclassname")[0];
div.innerHTML = div.innerHTML + "foobar";

This works fine.

But what if there is no class name but only the element tag like in

<cite>
<span>01.07.2016</span>
<span>sometext</span>
</cite>

How can I add "foobar" text at the end (after last span) but inside (!) the <cite> element?

Is there a function similar to getElementByElementName(...) which means I could write:

var div = document.getElementsByElementName("cite")[0];
div.innerHTML = div.innerHTML + "foobar";

It's called getElementsByTagName() and it's actually much older and better supported than getElementsByClassName.
