Function Details

function compareDocumentPosition

number compareDocumentPosition(Node n)

Compares a node with this node with regard to their position in the document and according to the document order.

When comparing two attribute nodes; 32 is returned if they have the same ownerElement, otherwise 0. This is probably not standard, but it’s what Firefox return, so we do the same.
