hive off nested childs

<!--
    i would like to hive off the nested child-node
    but in the correct order
    e.g.:
-->
<!-- source example 1-->

<span style="font-family: [Ohne];">
    <span style="font-family: qwe;">etu</span><!-- hive off this nested child-node above the parent -->
    restia volorsin
</span>

<!-- after xslt -->

<span style="font-family: [Ohne];">

    restia volorsin
</span>
<span style="font-family: qwe;">etu</span>


<!-- or  source example 2-->

<span style="font-family: [Ohne];">
    restia volorsin
    <span style="font-family: qwe;">etu</span><!-- hive off this nested child-node after the parent -->
</span>

<!-- after xslt -->

<span style="font-family: qwe;">etu</span>
<span style="font-family: [Ohne];">

    restia volorsin
</span>
