读取公共AWS S3存储桶中的文件计数

Question

我可以使用下面的代码检索包含有关文件信息的XML：

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

第一行代码返回以下xml。但我无法检索元素的数量：

<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>
        <Key>Bean Man with Affectiva.Editor.csproj</Key>

        <Size>34349</Size>
        <StorageClass>STANDARD</StorageClass>
    </Contents>
</ListBucketResult>

Answer 1

可以使用XElement代替XmlDocument responseXML = new XmlDocument(); responseXML.Load(AWS_S3_URL); XmlElement root = responseXML.DocumentElement; XmlNodeList node = root.GetElementsByTagName("Contents"); Debug.Log("responseXML.Elements() ===== " + node.Count); 轻松完成。

InfInt myint1 = "15432154865413186646848435184100510168404641560358";
    InfInt myint2 = 156341300544608LL;

    myint1 *= --myint2 - 3;
    std::cout << myint1 << std::endl;
