Description:
------------
We develop a contentsystem to access Adobe InCopy Documents out of a Primebase Database.  To read and parse the AIC (Adobe InCopy Document Format) we use the DOM XML extension.  UNfortunatly after reading the CLOB/BLOB out of the database an loading it via DOM XML ($dom->loadXML($string), PHP throws the warning "Extra content at the end of the document".  Not all the time, but irreguarly.  If I read the the BLOB, write it in a temp textfile and then read it via $dom->load($filename), everything works fine.  I have checked several times, the data out of the database is _always_ the same amd the XML is wellformed. Is there a memory leak in the loadXML method? 

Reproduce code:
---------------
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<aic:document xmlns:aic="http://ns.adobe.com/AdobeInCopy/2.0/" name="Hier steht eine Bildunterschrift f?r Bildbreite 65" ver="3.0">

<aic:story xml:space="preserve" track="0" dFont="Times" optalign="0" optsize="40280000 0"><aic:pstyle name="B_BU"/><aic:cstyle name="[No character style]"/>NEU!!!! Hier steht eine Bildunterschrift f?r Bildbreite 65,5</aic:story>
</aic:document>

[...]
primebase_cursor_bind($result, 0,PRIMEBASE_BLOB);
    while ($line = primebase_fetch_array($result)) {
    	$aicdocument = primebase_read_blob($line[content]);

    	$dom = new DOMDocument;
  		$dom->loadXML($aicdocument); }
echo htmlspecialchars(utf8_decode($dom->saveXML()));
[...]

Expected result:
----------------
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<aic:document xmlns:aic="http://ns.adobe.com/AdobeInCopy/2.0/" name="Hier steht eine Bildunterschrift f?r Bildbreite 65" ver="3.0">

<aic:story xml:space="preserve" track="0" dFont="Times" optalign="0" optsize="40280000 0"><aic:pstyle name="B_BU"/><aic:cstyle name="[No character style]"/>NEU!!!! Hier steht eine Bildunterschrift f?r Bildbreite 65,5</aic:story>
</aic:document>



Actual result:
--------------
Warning:  DOMDocument::loadXML() [function.loadXML]: Extra content at the end of the document in Entity, line: 6 in /usr/local/dreams/htdocs/k4_table_info.php on line 34
