JavaScript getElementsByTagName within specific container

In php, I can use getElementsByTagName on any DOM object but it seems JavaScript does not have that concept.

IE if the var detailsNode is a specific node, detailsNode.getElementsByTagName('summary') does not seem to work, firebug error says detailsNode.getElementsByTagName is not a function.

So, how do I target getElementsByTagName() to only look within a specified DOM element in JavaScript?

Thank you for suggestions.

Oh, and the answer needs to be straight up DOM2 method, no jQuery for this (where it would be easy).

Element and Node objects do have getElementsByTagName which returns an array of the found elements in the given Element/Node.
