如何根据name属性读取xml并获取值

Question

<root>
    <Message type="sms">
        <Details locale="en" message-type="User.ResetPassword" />
        <Context>
            <Parameter name="Time" value=" 16:03:31" />
            <Parameter name="pswr" value="00" />
            <Parameter name="Date" value="18/12/2014" />
        </Context>
        <Receiver>+923328749199</Receiver>
    </Message>
</root>

我该如何阅读此文件？例如，我想获得时间，密码和日期的值，以及接收者标记值。

      }
   }
}

代码反序列化后

var serializer = new XmlSerializer(typeof(root));

using (var file = File.OpenText("sample.xml"))
{
    root data = (root)serializer.Deserialize(file);

    // ... 
}

您可以使用数据按root对象访问所有成员。

希望帮助..........

Dim Xdoc As XDocument
    Xdoc = XDocument.Parse(pstrXmlInput)
    Dim Tktno = From Attbvalue In Xdoc.Descendants("Context").Elements("Parameter").Attributes("value")
                Select Attbvalue.Value

Answer 3

使用XDocument。

这是我的解决方案：

如果您的xml来自网址，请使用XDocument.Load（/ 网址 /）

var xml = "<root><Message type='sms'><Details locale='en' message-type='User.ResetPassword' /><Context><Parameter name='Time' value=' 16:03:31' /><Parameter name='pswr' value='00' /><Parameter name='Date' value='18/12/2014' /></Context><Receiver>+923328749199</Receiver></Message></root>";
var document = XDocument.Parse(xml);

var messages = document.Root.Elements();
foreach (var message in messages)
{
    var context = message.Element("Context");
    var parameters = context.Elements("Parameter");
    foreach (var parameter in parameters)
    {
        var name = parameter.Attribute("name").Value;
        var value = parameter.Attribute("value").Value;

        Console.WriteLine ("Parameter {0} with value of {1}", name, value);
    }

    Console.WriteLine ("Receiver {0}", message.Element("Receiver").Value);
}

<强>输出

Parameter Time with value of  16:03:31
Parameter pswr with value of 00
Parameter Date with value of 18/12/2014
Receiver +923328749199
