→util:ddo
==util:ddo==
{| width='100%'
|Returns nodes in ''distinct document order'': duplicate nodes will be removed, and the remaining nodes will be returned in [https://www.w3.org/TR/xquery-31/#dt-document-order document order]. All results of path expression are in distinct document order, so the function is equivalent to the expression <code>$nodes/self::node()</code>.

| '''Summary'''
|Returns Evaluates {{Code|$input}} and returns the result {{Code|$count}} instances of the specified times. Unless {{Code|$sequencemultiple}}is enabled, the input expression is only evaluated once. A similar result can be generated with The function call <code>util:replicate($input, $count, true())</code> is equivalent to <code>(1 to $count) ! $sequenceinput</code>, but in the latter case, the right-hand expression will be evaluated multiple times.

| '''Errors'''
|
* <code>util:replicate('A', 3)</code> returns <code>A A A</code>.
* In the following query, a single new element node is constructed, and {{Code|true}} is returned:
<syntaxhighlight lang="xquery">
let $nodes := util:replicate(<node/>, 2)
return $nodes[1] is $nodes[2]
</syntaxhighlight>
* In this query, two nodes are constructed, and the result is {{Code|false}}:
<syntaxhighlight lang="xquery">
let $nodes := util:replicate(<node/>, 2, true())
return $nodes[1] is $nodes[2]
</syntaxhighlight>
