Question

我正在使用返回以下xml的Web服务。在c＃中，我建立了连接并返回一个XmlNode类型的对象

我需要提取这些值主要是TIME_PERIOD =“2010”OBS_VALUE =“4796580” 我很感激帮助我

这是XML

<CompactData xmlns="http://www.SDMX.org/resources/SDMXML/schemas/v2_0/message" xmlns:inegi="urn:sdmx:org.sdmx.infomodel.keyfamily.KeyFamily=inegi:TIPO_B_DSD:compact" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.SDMX.org/resources/SDMXML/schemas/v2_0/message SDMXMessage.xsd urn:estat:sdmx.infomodel.keyfamily.KeyFamily=inegi:DSD_TIPO_B:1.0:compact inegi:DSD_TIPO_B_Compact.xsd">

</inegi:DataSet>
</CompactData>

Answer 1

使用此代码。

XmlDocument doc = new XmlDocument();
doc.LoadXml(xmlstring);
XmlNode dataNode = doc.SelectSingleNode("/*[local-name()='CompactData']/*[local-name()='DataSet']/*[local-name()='Series']/*[local-name()='Obs']");
String obsValue = dataNode.Attributes ["OBS_VALUE"];
String timePeriod = dataNode.Attributes["TIME_PERIOD"];

最好的方法是忽略命名空间并使用下面的代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;

namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XDocument doc = XDocument.Load(FILENAME);

            XElement obs = doc.Descendants().Where(x => x.Name.LocalName == "Obs").FirstOrDefault();

            string TIME_PERIOD = obs.Attribute("TIME_PERIOD").Value;
            string OBS_VALUE = obs.Attribute("OBS_VALUE").Value;
        }
    }
}

如何从xml读取数据？
