xml - XPath to get all child nodes (elements, comments, and text) without parent

Question

I need an XPath to fetch all ChildNodes ( including Text Element, Comment Element & Child Elements ) without Parent Element. Any help

Sample Example:

<DOC>
<PRESENTEDIN>
    <X>
        First Text Node #1 
        <y> Y can Have Child Nodes # 
            <child> deep to it </child> 
         </y>
         Second Text Node #2 <z/> 
    </X>
    <EVTS>
        <evt/>
        <evt>
            <mtg_descr> SAE 2006 World Congress &amp; Exhibition </mtg_descr>
            <sess_descr> Advanced Hybrid Vehicle Powertrains (Part 1 of 5) </sess_descr>
            <loc> Detroit,MI,United States </loc>
            <sess_prod_grp_cd> TSESS </sess_prod_grp_cd>
            <sess_evt_name> P13 </sess_evt_name>
            <sess_gen_num> 138352 </sess_gen_num>
            <mtg_start_dt> 04/03/2006 </mtg_start_dt>
            <mtg_end_dt> 04/06/2006 </mtg_end_dt>
            <desig> CONGRESS-2006 </desig>
        </evt>
    </EVTS>
    <EVTTYPE>PAPER</EVTTYPE>
    <SUPERTECH>
        <![CDATA[C8585]]>
    </SUPERTECH>
</PRESENTEDIN>

XPATH TRIED

   1. $doc/PRESENTEDIN/X
   2. $doc/PRESENTEDIN/X/descendant::*
   2. $doc/PRESENTEDIN/X/self::*

EXPECTED OUTPUT

    First Text Node #1 
    <y> Y can Have Child Nodes # 
        <child> deep to it </child> 
     </y>
     Second Text Node #2 <z/> 

I DON'T WANT

<X>
  First Text Node #1 
        <y> Y can Have Child Nodes # 
            <child> deep to it </child> 
         </y>
         Second Text Node #2 <z/> 
</X>

Answer 1

From the documentation of XPath ( http://www.w3.org/TR/xpath/#location-paths ):

child::* selects all element children of the context node

child::text() selects all text node children of the context node

child::node() selects all the children of the context node, whatever their node type

So I guess your answer is:

$doc/PRESENTEDIN/X/child::node()

And if you want a flatten array of all nested nodes:

$doc/PRESENTEDIN/X/descendant::node()
