xslt - Wrapping and moving child nodes -

could please me transforming following snippet?

<root>     <topic>                  <!-- first topic -->         <p>content1</p>         <topic>              <!-- second topic -->             <p>content2</p>         </topic>         <topic>              <!-- third topic -->             <p>content3</p>         </topic>     </topic> </root> 

i need cut second topic , third topic off first topic, wrap them in new/empty topic , attach new topic children root node.

<root>     <topic>                   <!-- first topic -->         <p>content1</p>     </topic>     <topic>                   <!-- new topic -->         <topic>               <!-- second topic -->             <p>content2</p>            </topic>         <topic>               <!-- third topic -->             <p>content3</p>         </topic>     </topic> </root> 

maybe there simple solution. tried prefix second/suffix third topic tag (looks dirty solution me), fail moving them.

<xsl:if test="position() = 1">     <![cdata[     <topic>     ]]>     ... </xsl:if>  <xsl:if test="position() = last()">     ...     <![cdata[     </topic>     ]]> </xsl:if> 

update 1 more complex , detailed example:

source - before transformation

<?xml version="1.0" encoding="utf-8"?> <root>   <!--     root has      title , multiple child     topics. no other child     elements.   -->   <title>root</title>   <topic id="topic_1">     <!--       allowed child elements of 'topic'       listed in dita spec.:       http://bit.ly/1ruybdq     -->     <title>first topic - first level</title>   </topic>   <topic id="topic_2">     <title>second topic - first level</title>     <!--       main problem.       topic must not contain       child topics , other child       elements after       transformation.       if topic has child topic       , other child elements,       topics have extracted.     -->     <topic id="topic_3">       <title>third topic - second level</title>     </topic>     <topic id="topic_4">       <!--         number of topics not limited.       -->        <title>fourth topic - second level</title>       <topic id="topic_5">         <!--           third level topics have           moved second           hierarchy level. no topic           may reside on third           level after transformation.         -->         <title>fifth topic - third level</title>       </topic>     </topic>   </topic> </root> 

result - after transformation

<?xml version="1.0" encoding="utf-8"?> <root>   <title>root</title>   <topic id="topic_1">     <title>first topic - first level</title>   </topic>   <topic id="topic_2">     <title>second topic - first level</title>   </topic>   <!--     third , fourth topic have     been moved extracted     second topic. both (could     number) have been wrapped     dummy 'topic' element.   -->    <topic>     <!--        second level topics have       been wrapped "dummy"       topic element.     -->     <topic id="topic_3">       <title>fourth topic - second level</title>     </topic>     <topic id="topic_4">       <title>fifth topic - second level</title>     </topic>      <topic id="topic_5">       <!--         third level topic         has been moved         second hierarchy level.         -->       <title>sixth topic - third level</title>     </topic>   </topic> </root> 

maybe there simple solution.
