Description:
------------
using the method textContent on a node using teh php 5 DOM 
retrieves the cdata for every child as well - that doesn't 
seem right. it certainly is useless 

Reproduce code:
---------------
XML
--------------
<?xml version="1.0"  ?> 
<base> 
I see
    <item>   
       stuff 
    </item> 
    <item>   
       and
    </item> 
   <item>   
       more 
      <subitem>stuff</subitem>
    </item> 
    
</base> 

PHP
-----------
$root = $this->registry->getElementsByTagName('base');
       
        foreach($root as $node) { 
            print $node->textContent . " "; 
        } 

Expected result:
----------------
I see 

Actual result:
--------------
I see stuff and more stuff
