There are at least a couple of different approaches to this via the typeswitch
strategy, but I think the simplest would be:
1. In your function for closer, recurse over the child nodes as usual (which I
assume will output a <closer> element, or whatever you transform it to), then
process your postscript children:
for $ps in $node/tei:postscript
return <postscript>{$ps/@*, eccoparse:recurse($ps)}</postscript>
2. Extend your postscript function so it returns null if the postscript is a
child of <closer>:
declare function eccoparse:postscript($node as element(tei:postscript)) as
element()*
{
if ($node/parent::tei:closer) then ()
else <postscript>{$node/@*}{eccoparse:recurse($node)}</postscript>
}
Speaking as someone who wrote a lot of pseudo-templates in XQuery before
MarkLogic added an XSLT 2.0 parser to their product, this is one area where XSLT
is a lot more pleasant to use, if that's a possibility.

I want to move the <postscript> element from its position as the last child
of <closer> into the position of right sibling of <closer> so that the
desire output would look like this:
<closer>
<signed>Your ever affectionate WOODVILLE.</signed>
</closer>
<postscript>

How do I do this? In a typeswitch function the different tasks relating to
elements are carried out by subsidiary function. Here is the postscript
function that simply passes through the element:
declare function eccoparse:postscript($node as element(tei:postscript)) as
element()
{
<postscript>{$node/@*}{eccoparse:recurse($node)}</postscript>
};
I know how to various things that would change the postscript element but
leave it in its current place. But how do I put it in another place without
changing anything in it? Is this a task that should be done at the level of
the parent element?
I'll be grateful for any advice.
