Java: Most efficient method to iterate over all elements in a org.w3c.dom.Document?

Question

What is the most efficient way to iterate through all DOM elements in Java?

Something like this but for every single DOM elements on current org.w3c.dom.Docume

Answer 1

for (int i = 0; i < nodeList.getLength(); i++)

change to

for (int i = 0, len = nodeList.getLength(); i < len; i++)

to be more efficient.

The second way of javanna answer may be the best as it tends to use a flatter, predictable memory model.
