XPath for extracting all the element+attribute nodes

This is my XML test text:
"<memo author="Pat Coleman"><to>Carole Poland</to></memo>"

How can I get with XPath/XML DOM a node-set containing all the element and attribute nodes?

is   $obj.selectNodes('//@*|//*')   the shortest/most efficient solution?

This question can not be answered without context

$obj.selectNodes('//@*|//*')

is likely the "shortest" solution in terms of XPath clarity and consiseness

However, I don't think I would ever do that without knowing at least a little about the optimisations going on inside the processor. A naive processor would walk the three twice, once for the elements and once for the attributes

If this were a XPath2 processor, I would do something like
$obj.selectNodes('//node()/(self::* | @*)')
to force into only one tree-walk regardless of processor optimisations

the save approach would be
$obj.selectNodes('//*')
then iterate the array, and for each node add the getAttributes
If you ask for efficiency, that will almost always beat it
