Xquery compare two nodesets

Issue

Compare two nodesets for equality using xquery

Resolution

Use a recursive function to runa deep-equal() function across all nodes

Xquery

declare function utils:deep-equal($node1 as element(), $node2 as element()) as xs:boolean {
    let $equal as xs:boolean := deep-equal($node1, $node2)
    return (
      if (not($equal) or empty($node1/*)) then $equal
      else  (
        every $de in (
            for $n in $node1/*
            let $position := count($n/preceding-sibling::*)+1
            return utils:deep-equal($n, $node2/*[$position])
            )
        satisfies $de = true()
        )
    )
};
