SaveXml in php returning empty string - php

Question

I have the following xml :
<assumption_list>
<assumption name="test" id="23" description="test1" is_shared="no">
<watchlists>
<watchlist globalissuer="koolwater" prepayrate="5" prepaytype="CPR" defaultrate="5" defaulttype="CDR" lossrate="7" lagmonths="2"/>
</watchlists>
</assumption>
</assumption_list>
I load the following received from a jsp call in php as DOMDocument
I am trying the get the <watchlists> node as a string by using the following code :
$result = $xmlDoc->getElementsByTagName('watchlists');
$strxml='';
foreach($result as $element)
{
print_r(simplexml_import_dom($element));
$strxml = $xmlDoc->saveXML($element);
var_dump($strxml);
}
I do see my print_r(simplexml_import_dom($element)); this getting populated but for some reasons i see the empty string after the saveXml operation. Is there something wrong with the current implementation.
I am trying to get the xml string representation so that i can pass the xml string to c# dll used by php application

If you want to output the xml string representation, you can use a simple htmlentities() on this one. Consider this example: Sample Output
$xmlDoc = '<assumption_list> <assumption name="test" id="23" description="test1" is_shared="no"> <watchlists> <watchlist globalissuer="koolwater" prepayrate="5" prepaytype="CPR" defaultrate="5" defaulttype="CDR" lossrate="7" lagmonths="2"/> </watchlists> </assumption></assumption_list>';
$xmlDoc = simplexml_load_string($xmlDoc);
$result = $xmlDoc->assumption->watchlists->watchlist;
// echo $result->asXML(); // output as xml
echo htmlentities($result->asXML()); // output as xml string
