c#解析XML
1、引入using system.xml;
2、相应代码
XmlDocument doc = new XmlDocument();
doc.LoadXml(content);
XmlNamespaceManager nsMgr = new XmlNamespaceManager(doc.NameTable);
nsMgr.AddNamespace("a", "http://schemas.datacontract.org/2004/07/EnvCriteria.Model");
XmlNodeList dataNode = doc.SelectNodes("//a:Tab_AQIPublishInfo", nsMgr);
foreach (XmlNode node in dataNode)
{
string positionName = node.SelectSingleNode("./a:PositionName", nsMgr).InnerText.Trim();
if (!NameToStation.ContainsKey(positionName))
{
common.LOG.errorLog("a new station is added to Guangdong air quality. " + positionName);
continue;
}
AirQuality airquality = new AirQuality();
airquality.station_id = NameToStation[positionName].ID;
airquality.PM25_Concentration = ToDouble(node.SelectSingleNode("./a:PM2_5", nsMgr).InnerText.Trim());
airquality.PM10_Concentration = ToDouble(node.SelectSingleNode("./a:PM10", nsMgr).InnerText.Trim());
airquality.NO2_Concentration = ToDouble(node.SelectSingleNode("./a:NO2", nsMgr).InnerText.Trim());
airquality.SO2_Concentration = ToDouble(node.SelectSingleNode("./a:SO2", nsMgr).InnerText.Trim());
airquality.O3_Concentration = ToDouble(node.SelectSingleNode("./a:O3", nsMgr).InnerText.Trim());
airquality.CO_Concentration = ToDouble(node.SelectSingleNode("./a:CO", nsMgr).InnerText.Trim());
airquality.time = Convert.ToDateTime(node.SelectSingleNode("./a:TimePoint", nsMgr).InnerText.Trim());
list.Add(airquality);
}
