xquery - Ordering of nodes after in memory update with mem:insert-child() is inconsistent -


i using ryan dew's xquery module (https://github.com/ryanjdew/xquery-xml-memory-operations) marklogic v8.0-5 perform in-memory updates document.

the following code sample replicates problem experience when use insert-child() operation. elements inserted insert-child() should reflect insertion order, find not. in other words, elements should ordered one, two, three, four, 5 in output. instead, order appears random.

let $x := <root><original-container><one/><two/><three/><four/><five/></original-container><new-container/></root> let $tx := mem:copy($x) let $_ :=    $item in $x/original-container/*    return (        xdmp:set( $tx, mem:delete($tx, $item) ) ,        xdmp:set( $tx, mem:insert-child($tx, $x/new-container, $item) )    )  return mem:execute( $tx )

i may misusing code library--in particular, creating transaction map , resetting xdmp:set() after each insert-child() operation. perhaps not correct?

i apologize, bug in code. expression returning nodes in "document order" , across documents can appear random. i've committed fix , more details can found @ the ticket on github.
