Read xml from url
This is what I have so far. I am trying to just read XML from a url and just get e.g. temperature, humidity ... etc. But every time I try something else it gives me an error. I want to get information and put it in a label.
namespace WindowsFormsApplication1 {
public partial class Form1: Form {
public Form1() {
InitializeComponent();
}
private void btnSubmit_Click(object sender, EventArgs e) {
String zip = txtZip.Text;
XmlDocument weatherURL = new XmlDocument();
weatherURL.Load("http://api.wunderground.com/api/"
your_key "/conditions/q/" + zip + ".xml");
foreach(XmlNode nodeselect in weatherURL.SelectNodes("response/current_observation"));
}
}
}

It took me a bit of trial and error, but I got it. In C #, make sure you are using - using System.Xml;
Here is the code using the wunderground API. For this to work, make sure you subscribe to a different key key, but that won't work. Where they say it is your_key where you paste your key. It should look something like this. I used a button and three shortcuts to display information.
namespace wfats2
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
XmlDocument doc1 = new XmlDocument();
doc1.Load("http://api.wunderground.com/api/your_key/conditions/q/92135.xml");
XmlElement root = doc1.DocumentElement;
XmlNodeList nodes = root.SelectNodes("/response/current_observation");
foreach (XmlNode node in nodes)
{
string tempf = node["temp_f"].InnerText;
string tempc = node["temp_c"].InnerText;
string feels = node["feelslike_f"].InnerText;
label2.Text = tempf;
label4.Text = tempc;
label6.Text = feels;
}
}
}
}
When you press the button, you will receive the information displayed in the label assignment. I am still experimenting and you can update every time as often as opposed to pressing a button every time to get the update.
