我试图获取谷歌天气数据如下:
try
{
string cityName = txtCityName.Text;
//Format the google URL with CityName
string weatherURL = string.Format("http://www.google.com/ig/api?weather={0}", cityName);
//Parse the XML URL and get the Data
var weatherXML = XDocument.Parse(weatherURL);
var weatherResult = from weatherDetail in weatherXML.Descendants("current_conditions")
select new currentWeatherCondition
{
condition = ((string)weatherDetail.Element("condition").Attribute("data")).Trim(),
temp = ((string)weatherDetail.Element("temp_c").Attribute("data")).Trim(),
imageURL = ((string)weatherDetail.Element("icon").Attribute("data")).Trim(),
};
}
catch (Exception err)
{
Response.Write(err.Message.ToString());
}
我收到异常* 根级别的数据无效。第1行,位置1. * 因为我没有传递XML数据而是URL。如何将XML数据传递到解析器
答案 0 :(得分:2)
Parse期待一个用XML填充的字符串
使用XDocument.load(我认为会使用url),或者使用webrequest获取xml字符串并在
中传递
