E4X get element's next sibling

Question

Hey,

I have a reference to a XML node which is part of a bigger XML tree. Is there a way to get that elements next/previous sibling without accessing the parent and looking for it? Something like DOM's nextSibling would be what I look for.

edit: Given that there is no natural way to do this with E4X, I'll just stick to the following (except that in my case, I'll store the actual index somewhere instead):

// next sibling:
node.parent().children()[ node.childIndex() + 1 ]
// previous sibling:
node.parent().children()[ node.childIndex() - 1 ]

Is this what you are looking for?

I don't see any such methods in ECMA-357, 2nd edition. Moreover, "sibling" doesn't seem to appear anywhere in my copy of the standard. If any such methods exist, they exist because Adobe added them as extensions to the spec.
