读取公共AWS S3存储桶中的文件计数

Question

I am able to retrieve the XML which contains the info about the files using the below piece of code:

XElement responseXML = XElement.Load(AWS_S3_URL);        
ICollection<XElement> fileElements = responseXML.Elements("Contents") as ICollection<XElement>;
Debug.Log("responseXML.Elements() ===== " + fileElements.ToString());

The first line of code returns the following xml. But I am not able to retrieve the count of element:

<ListBucketResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
    <Name>XXXXXXXXXXXX</Name>
    <Prefix />
    <Marker />
    <MaxKeys>1000</MaxKeys>
    <IsTruncated>false</IsTruncated>
    <Contents>
        <Key>AffectivaLogs/</Key>

    </Contents>
</ListBucketResult>

Able to do it easily using XmlDocument instead of XElement .

XmlDocument responseXML = new XmlDocument();
responseXML.Load(AWS_S3_URL);
XmlElement root = responseXML.DocumentElement;
XmlNodeList node = root.GetElementsByTagName("Contents");        
Debug.Log("responseXML.Elements() ===== " + node.Count);
