Thanks Gabriel, not really a complete answer, but it did lead me to [[LINK href="http://stackoverflow.com/questions/15312554/using-wp-remote-get-to-work-with-xml-in-wordpress"]]this entry on StackOverflow[[/LINK]] which in turn enabled me to produce:
$url = 'http://api.facebook.com/restserver.php?method=links.getStats&urls=http://www.techcrunch.com';
$response = wp_remote_get( $url );
$body = wp_remote_retrieve_body( $response );
$xml = simplexml_load_string( $body );
$like_count = $xml->link_stat->like_count;
echo $like_count;

if ( $xml ) {
print_r($xml);

Produces an error message unfortunately ... simplexml_load_string(): Entity: line 1: parser error
