Description:
------------
If you create an element on a DOMDocument, and then append a CDATA section to the node, if formatOutput is enabled, it makes the node put a return caridge before and after the CDATA section. IE: 
        <key_0>
<![CDATA[BLAHBLAH]]>
        </key_0>

This is problematic, as when you fetch the data from the node, it carries the return caridges with it. The only way of solving this currently (that I know of) is to not use formattput on the DOMDocument.


Reproduce code:
---------------
<?php
   $dom = new DOMDocument("1.0");
   $dom->formatOutput = true;
   $node = $dom->createElement("node");
   $cdata = $dom->createCDATASection("BLAH BLAH BLAH");
   $dom->appendChild($node);
   $node->appendChild($cdata);
   $dom2 = DOMDocument::loadXML($dom->saveXML());
   $rootNode = $dom2->documentElement;
   $text = $rootNode->textContent;
   print("'$text'");
   $packData = @unpack("H*", $text);
   print_r($packData);
?>

Expected result:
----------------
'BLAH BLAH BLAH'Array
(
    [1] => 424c414820424c414820424c4148
)


Actual result:
--------------
'
BLAH BLAH BLAH
'Array
(
    [1] => 0a424c414820424c414820424c41480a
)
//you can see the 0A after the ' and before the closing '
