[英]Extracting values from XML returned by azure service management API
我嘗試了幾種嘗試從XML文件中提取值的方法,但它們似乎都不起作用。 我正在使用C#。 XML如下
<?xml version="1.0" encoding="utf-8"?>
<HostedService xmlns="http://schemas.microsoft.com/windowsazure">
<Url>hosted-service-url</Url>
<ServiceName>hosted-service-name</ServiceName>
<HostedServiceProperties>
<Description>description</Description>
<Location>location</Location>
<AffinityGroup>affinity-group</AffinityGroup>
<Label>label</Label>
</HostedServiceProperties>
</HostedService>
我想檢索托管服務網址,托管服務名稱,描述,位置,相似性組和標簽
檢索這些值的最佳方法是什么?
編輯:
感謝LB,該方法非常有效。 但是,我剛剛被告知,我將不得不使用下面更大的XML。
<?xml version="1.0" encoding="utf-8"?>
<HostedService xmlns="http://schemas.microsoft.com/windowsazure">
<Url>hosted-service-url</Url>
<ServiceName>hosted-service-name</ServiceName>
<HostedServiceProperties>
<Description>description</Description>
<Location>location</Location>
<AffinityGroup>affinity-group</AffinityGroup>
<Label>base-64-encoded-name-of-the-service</Label>
</HostedServiceProperties>
<Deployments>
<Deployment>
<Name>deployment-name</Name>
<DeploymentSlot>deployment-slot</DeploymentSlot>
<PrivateID>deployment-id</PrivateID>
<Status>deployment-status</Status>
<Label>base64-encoded-deployment-label</Label>
<Url>deployment-url</Url>
<Configuration>base-64-encoded-configuration-file</Configuration>
<RoleInstanceList>
<RoleInstance>
<RoleName>role-name</RoleName>
<InstanceName>role-instance-name</InstanceName>
<InstanceStatus>instance-status</InstanceStatus>
</RoleInstance>
</RoleInstanceList>
<UpgradeDomainCount>upgrade-domain-count</UpgradeDomainCount>
<RoleList>
<Role>
<RoleName>role-name</RoleName>
<OsVersion>operating-system-version</OsVersion>
</Role>
</RoleList>
<SdkVersion>sdk-version-used-to-create-package</SdkVersion>
<InputEndpointList>
<InputEndpoint>
<RoleName>role-name</RoleName>
<Vip>virtual-ip-address</Vip>
<Port>port-number</Port>
</InputEndpoint>
…
</InputEndpointList>
<Locked>deployment-write-allowed-status</Locked>
<RollbackAllowed>rollback-operation-allowed</RollbackAllowed>
</Deployment>
</Deployments>
</HostedService>
我的最后一個問題是,有幾個重復的標簽,例如,
我如何區分它們?
您可以使用Xml對Linq解析您的xml字符串。 例如,
var xElem = XElement.Load(new StringReader(xml));
var ns = XNamespace.Get("http://schemas.microsoft.com/windowsazure");
var obj = new
{
ServiceName = xElem.Descendants(ns + "ServiceName").First().Value,
Description = xElem.Descendants(ns + "Description").First().Value,
};
或者您可以使用XmlSerializer
XmlSerializer xs = new XmlSerializer(typeof(HostedService), "http://schemas.microsoft.com/windowsazure");
var obj2 = (HostedService)xs.Deserialize(new StringReader(xml));
public class HostedService
{
public string Url;
public string ServiceName;
public HostedServiceProperties HostedServiceProperties;
}
public class HostedServiceProperties
{
public string Description;
public string Location;
public string AffinityGroup;
public string Label;
}
也許您可以嘗試從XmlDocument( http://msdn.microsoft.com/en-us/library/d271ytdx.aspx )和LINQ to XML-( http://msdn.microsoft.com/zh-cn/library /bb669152.aspx ),然后將其應用於您的案例。
