PHP echo objects from an XML document where there are duplicate nodes

I have been using the Bing Maps API to get traffic incidents from a certain area. This would then create an XML document, I can access objects that are single nodes but can't echo any nodes that are nested within other nodes. The XML document looks like:

<Response xmlns:xsd="http://ift.tt/tphNwY" xmlns:xsi="http://ift.tt/ra1lAU" 
 xmlns="http://ift.tt/1prkLAu">
<Copyright>
 - Message -
</Copyright>
<BrandLogoUri>
  - Logo -
 </BrandLogoUri>
 <StatusCode>200</StatusCode>
 <StatusDescription>OK</StatusDescription>
 <AuthenticationResultCode>ValidCredentials</AuthenticationResultCode>
 <TraceId>
  - Trace ID- 
 </TraceId>
 <ResourceSets>
 <ResourceSet>
 <EstimatedTotal>1</EstimatedTotal>
 <Resources>
 <TrafficIncident>
 <Point>
 <Latitude> - Latitude - </Latitude>
 <Longitude>- Longitude -</Longitude>
 </Point>
 <IncidentId>- IncidentId -</IncidentId>
 <LastModifiedUTC>- Time -</LastModifiedUTC>
 <StartTimeUTC>- Time -</StartTimeUTC>
 <EndTimeUTC>- Time -</EndTimeUTC>
 <Type>- Type -</Type>
 <Severity>- Severity -</Severity>
 <Verified>- True -</Verified>
 <RoadClosed>- True -</RoadClosed>
 <Description>
  - Description - 
 </Description>
 <ToPoint>
 <Latitude>-Latitude -</Latitude>
 <Longitude>- Longitude -</Longitude>
 </ToPoint>
 </TrafficIncident>
 </Resources>
 </ResourceSet>
 </ResourceSets>
 </Response>

To echo the objects in a single node I have been using the following PHP Code: "; echo $xml->TraceId . "

"; echo $xml->Copyright . "

"; echo $xml->Verified . "

"; ?> To echo the Latitude which is in a nested node I have tried the PHP code: foreach($xml->TrafficIncident->Point->Latitude as $row){ echo''.$row.''; }

But so far no luck. Any Ideas?
