Swapping nodes in a DOM tree

by Pascal Opitz

published 12 April 2007

I was quite surprised to find out that the insertBefore method actually does most of the job for you.
A detail in the manual offers us insight in how: "If the newChild is already in the tree, it is first removed."

Hence: 

myNode.parentNode.insertBefore(myNode, myNode.nextSibling);

  1. haha, the manual.
    That is actually quite nice to know. Is it implemented correctly in all the usual PHP, JS, different browsers whatever? And when can I add Ruby (on, over, under or without Rails) to that list?
