从 google api 解析 xml 数据

Question

我有一个谷歌地图链接，它返回一个 xml 给我。我想要该 xml 中特定标记的值。有人可以建议我该怎么做吗？链接:

http://maps.google.com/maps/api/geocode/xml?address=1270 Broadway Ste 803, New York, NY 10001, USA&sensor=false

Answer 1

这是一个返回字典中坐标的函数。注意:这是新的 V3 api。无需 API key 。传感器是。

    // Figure out the geocoordinates for the location
private Dictionary<string, string> GeoCode(string location)
{
    // Initialize the dictionary with empty values.
    Dictionary<string, string> dic = new Dictionary<string, string>();
    dic.Add("latitude", "");
    dic.Add("longitude", "");

    try
    {
        string url = "http://maps.google.com/maps/api/geocode/xml?address=" + System.Web.HttpUtility.UrlEncode(location) + "&sensor=false";
        XmlDocument doc = new XmlDocument();
        doc.Load(url);
        XmlNodeList nodes = doc.SelectNodes("//location");

        // We're assuming there's only one location node in the xml.
        foreach (XmlNode node in nodes)
        {
            dic["latitude"] = node.SelectSingleNode("lat").InnerText;
            dic["longitude"] = node.SelectSingleNode("lng").InnerText;
        }
    }
    catch (Exception)
    {
        // If anything goes wrong, we want to get empty values back.
        dic["latitude"] = "";
        dic["longitude"] = "";
    }

    return dic;
}
