Reply to: node list issues/questions

It is tied more directly to your nodelist object (variable) and the values it contains, so that (in theory) if you were to iterate through the list of nodes once and set the attribute values, then iterate through a second time and read the attribute values the read operation would reflect the current state after the first iteration (not the original state) of the document's nodes. The confusion that most people might have with this is that you are not dealing with things purely in script here, you are actually making real modifications to the document.
