解析Web服务响应返回的xml

Question

我已经阅读了很多关于这个主题的问题,但我似乎与我想要做的事情有关.基本上我正在调用一个Web服务来返回有关车辆识别号(VIN)的信息.它返回一个如下所示的xml流:

<VINquery Version="1.0.0" Date="5/25/2003">
  <VIN Number="1HGES15501Lxxxxxx" Status="SUCCESS">
    <Vehicle VINquery_Vehicle_ID="23261" Model_Year="2001" Make="Honda" Model="Civic" Trim_Level="LX Sedan">
      <Item Key="VINquery Vehicle ID" Value="23261" Unit=""/>
      <Item Key="Model Year" Value="2001" Unit=""/>
      <Item Key="Make" Value="Honda" Unit=""/>
      <Item Key="Model" Value="Civic" Unit=""/>
      <Item Key="Trim Level" Value="LX Sedan" Unit=""/>
      <Item Key="Manufactured in" Value="UNITED STATES" Unit=""/>
      <Item Key="Production Seq. Number" Value="xxxxxx" Unit=""/>
      <Item Key="Body Style" Value="SEDAN 4-DR" Unit=""/>
      <Item Key="Engine Type" Value="1.7L L4 SOHC 16V" Unit=""/>
      <Item Key="Transmission-short" Value="5M OD" Unit=""/>
      <Item Key="Transmission-long" Value="5-Speed Manual Overdrive" Unit=""/>
      <Item Key="Driveline" Value="FWD" Unit=""/>
      <Item Key="Tank" Value="13.20" Unit="gallon"/>
      <Item Key="Fuel Economy-city" Value="30 - 32" Unit="miles/gallon"/>
      <Item Key="Fuel Economy-highway" Value="38 - 39" Unit="miles/gallon"/>
      <Item Key="Anti-Brake System" Value="Non-ABS" Unit=""/>
      <Item Key="Steering Type" Value="R&P" Unit=""/>
      <Item Key="Standard Seating" Value="5" Unit=""/>
      <Item Key="Optional Seating" Value="No data" Unit=""/>
      <Item Key="Length" Value="174.60" Unit="in."/>
      <Item Key="Width" Value="67.50" Unit="in."/>
      <Item Key="Height" Value="56.70" Unit="in."/>
    </Vehicle>
  </VIN>
</VINquery>

我想获取该数据并为每个键/值解析它.这是我的代码我使用获取xml数据:

private string baseURL = "http://ws.vinquery.com/restxml.aspx?accessCode=xxxxxx&vin=xxxxxxxxx";
private string reportType = "&reportType=2";

public XmlDocument ExplodeVIN(string strVIN)
{
   DataTable dt = new DataTable();

   string url = baseURL + strVIN + reportType;

   HttpWebRequest req = WebRequest.Create(url) as HttpWebRequest;

   XmlDocument xmlDoc = new XmlDocument();
   using (HttpWebResponse resp = req.GetResponse() as HttpWebResponse)
   {
     xmlDoc.Load(resp.GetResponseStream());
   }
   return xmlDoc;
}

我得到xmlDoc后我不知道下一步该做什么.

谢谢你的帮助.

Answer 1

您可以Dictionary<string, string>使用Linq 解析xml 到Xml:

var xdoc = XDocument.Parse(xml);
var items = xdoc.Descendants("Item")
                .ToDictionary(i => (string)i.Attribute("Key"),
                              i => (string)i.Attribute("Value"));

用法:

string driveline = items["Driveline"];

要么

foreach(var kvp in items)
    // use key value pair
