Description:
------------
import of nodes named as "link" kills trailing-slashs/-tags?

Test script:
---------------
$xml = new DOMDocument;
$xml_dir = $xml->createElement("item");

$pagedoc = new DOMDocument;
$pagedoc->load($broadcaster.'test.xml');

$xml_page = $xml->createElement("page");
$xml_page = $xml->importNode($pagedoc->documentElement, true);

$xml_dir->appendChild($xml_page);

$xml->appendChild($xml_dir);


## file 1
<root>
	<subs>
		<route dispatch="root:abc" />
		<route disptach="root:def">def</route>
	</subs>
</root>


#### file 2
<root>
	<subs>
		<link dispatch="root:abc" />
		<link disptach="root:def">def</link>
	</subs>
</root>


Expected result:
----------------
## -> file 1

<mainstage>
	<item>
		<root>
			<subs>
				<route dispatch="root:abc"/>
				<route disptach="root:def">def</route>
			</subs>
		</root>
	</item>
</mainstage>

## -> file 2
<mainstage>
	<item>
		<root>
			<subs>
				<link dispatch="root:abc"/>
				<link disptach="root:def">def</link>
			</subs>
		</root>
	</item>
</mainstage>

Actual result:
--------------
## -> file 1

<mainstage>
	<item>
		<root>
			<subs>
				<route dispatch="root:abc"/>
				<route disptach="root:def">def</route>
			</subs>
		</root>
	</item>
</mainstage>

## -> file 2
<mainstage>
	<item>
		<root>
			<subs>
				<link dispatch="root:abc">
				<link disptach="root:def">
			</subs>
		</root>
	</item>
</mainstage>
