I tested the XML Aggregation feature against RSS feeds from the FinalBuilder build management tool. The xmlagg.php was failing with the following error:

Fatal error: Call to a member function getAttribute() on a non-object in C:\Inetpub\forum.mmrd.com\scripts\xmlagg.php on line 166

I noted that this line of the code was trying to pull out a link to fill in the {link} label in a feed post signature. In my case, there was no link.

I changed the relevant area of xmlagg.php from:

162		// Apply custom signature, may contain {link} tag.
163		if ( isset($node->getElementsByTagName('link')->item(0)->nodeValue)) {
164		    $link = $node->getElementsByTagName('link')->item(0)->nodeValue;
165		} else {
166		    $link = $node->getElementsByTagName('link')->item(0)->getAttribute('href');
167		}

to:

162		// Apply custom signature, may contain {link} tag.
163		if ( isset($node->getElementsByTagName('link')->item(0)->nodeValue)) {
164		    $link = $node->getElementsByTagName('link')->item(0)->nodeValue;
165		} else if ($node->getElementsByTagName('link')->length > 0) {
166		    $link = $node->getElementsByTagName('link')->item(0)->getAttribute('href');
167		}
