C#解析xml文件获取中国的省市县名称获zipcode编号。需要提交加载xml文件。获取市级城市时，需要提供省级名称。获取县级城市市需要提供省级和市级城市名称。

需要province.xml文件，下载

测试代码

static void Main()
{
XmlDocument doc=new XmlDocument();
doc.Load("province.xml");
List<string> allprovince = getProvince(doc);
for (int i = 0; i < allprovince.Count; i++)
{
System.Console.WriteLine(allprovince[i]);
}
List<string> allcity = getCity(doc, "安徽省");
for (int i = 0; i < allcity.Count; i++)
{
System.Console.WriteLine(allcity[i]);
}
List<string> allcounty = getCounty(doc, "安徽省", "安庆市");
for (int i = 0; i < allcounty.Count; i++)
{
System.Console.WriteLine(allcounty[i]);
}
}

获取省级城市名称

public static List<String> getProvince(XmlDocument doc)
{
List<String> provincelist = new List<string>();
XmlNode provinces = doc.SelectSingleNode("/root");
foreach (XmlNode province1 in provinces.ChildNodes)
{
provincelist.Add(province1.Attributes["name"].Value);
}
return provincelist;
}

获取市级城市名称

public static List<String> getCity(XmlDocument doc, String provincestr)
{
List<String> citylist = new List<string>();
string xpath = string.Format("/root/province[@name='{0}']/city", provincestr);
XmlNodeList cities = doc.SelectNodes(xpath);
foreach (XmlNode city1 in cities)
{
citylist.Add(city1.Attributes["name"].Value);
}
return citylist;
}

获取县级城市名称

public static List<String> getCounty(XmlDocument doc, String provincestr, String citystr)
{
List<String> qulist = new List<string>();
string xpath = string.Format("/root/province[@name='{0}']/city[@name='{1}']/district", provincestr, citystr);
XmlNodeList area = doc.SelectNodes(xpath);
foreach (XmlNode area1 in area)
{
qulist.Add(area1.Attributes["name"].Value);
}
return qulist;

}
