I have an XML feed that I’ve retrieved via httpwebrequest, and I’m having problems

  • 0

I have an XML feed that I’ve retrieved via httpwebrequest, and I’m having problems parsing the feed since its unlike the times I’ve tried this in the past. So far I have the url
http://webservices.nextbus.com/service/publicXMLFeed?command=routeConfig&a=sf-muni&r=N

which I’ve stored in

 XDocument doc = XDocument.Parse(feedString);

And I know that when I’ve dumped that all in a listbox for debugging purposes, I get everything there, I’m just having problems parsing the feed:

<body copyright="All data copyright San Francisco Muni 2012.">
<route tag="N" title="N-Judah" color="003399" oppositeColor="ffffff" latMin="37.7601699" latMax="37.7932299" lonMin="-122.5092" lonMax="-122.38798">
<stop tag="5240" title="King St & 4th St" lat="37.7760599" lon="-122.39436"   stopId="15240"/>
<stop tag="5237" title="King St & 2nd St" lat="37.7796199" lon="-122.38982" stopId="15237"/>
<stop tag="7145" title="The Embarcadero & Brannan St" lat="37.7846299" lon="-122.38798" stopId="17145"/>
<stop tag="4510" title="Embarcadero Folsom St" lat="37.7907499" lon="-122.3898399" stopId="14510"/>
<stop tag="5629" title="Tunnel Entry Point Inbound Nea" lat="37.79279" lon="-122.39126" stopId="15629"/>

And so on and so on

I’d like to store each attribute in each stop tag into an array, but I’m completely stumped as to how I’d begin even.

Thanks

Update:
I think I got it to work on that first msdn link, but this only gets the first line:

 using (XmlReader reader = XmlReader.Create(new StringReader(feed)))
        {
            reader.ReadToFollowing("stop");
            reader.MoveToFirstAttribute();
            string tag = reader.Value;


            reader.MoveToNextAttribute();
            string title = reader.Value;

            reader.MoveToNextAttribute();
            string lat = reader.Value;

            reader.MoveToNextAttribute();
            string lon = reader.Value;


        }

How would I loop through each stop with that code above?

Thanks

EDIT: #2

This loop works, but keeps showing the first row of stop attributes:

using (XmlReader reader = XmlReader.Create(new StringReader(feed)))
           {
               reader.ReadToFollowing("stop");
               while (reader.MoveToNextAttribute())
               {

               // Move the reader back to the element node.



                   //reader.ReadToFollowing("stop");
                   reader.MoveToFirstAttribute();
                   string tag = reader.Value;
                   MessageBox.Show(tag);

                   reader.MoveToNextAttribute();
                   string title = reader.Value;
                   MessageBox.Show(title);
                   reader.MoveToNextAttribute();
                   string lat = reader.Value;
                   MessageBox.Show(lat);
                   reader.MoveToNextAttribute();
                   string lon = reader.Value;
                   MessageBox.Show(lon);


               }
               reader.MoveToElement();
           }

I feel like I’m so close to figuring it out.

    Here is something you can use:

    XmlReader xmlReader = XmlReader.Create("http://webservices.nextbus.com/service/publicXMLFeed?   command=routeConfig&a=sf-muni&r=N");
List<string> aTitle= new List<string>();

// Add as many as attributes you have in your "stop" element

while (xmlReader.Read())
{
 //keep reading until we see your element
 if (xmlReader.Name.Equals("stop") && (xmlReader.NodeType == XmlNodeType.Element))
 {
   string title = xmlReader.GetAttribute("title");
   aTitle.Add(title);

   // Add code for all other attribute you would want to store in list.
  }
}

    Finally call the list and based on index you can get all the items.
