Parsing simple XML error

[Diamonddrake]

I am working on a little USPS tracking class, very simple calls web api returns xml, parses the xml to an object, passes that object back via an event.

for some reason I can't seem to get the XML to parse correctly. I there are an unknown amount of a certain node in the root node, so deserialization is out, but using XMLReader I can only get the first value from the TrackDetails nodes.

Here is the xml example

<?xml version="1.0"?>

<TrackResponse><TrackInfo ID="EJ958088694US"><TrackSummary>

Your item was delivered at 1:39 pm on June 1 in WOBURN MA 01815.

</TrackSummary><TrackDetail>

May 30 7:44 am NOTICE LEFT WOBURN MA 01815.

</TrackDetail><TrackDetail>

May 30 7:36 am ARRIVAL AT UNIT NORTH READING MA 01889.

</TrackDetail><TrackDetail>

May 29 6:00 pm ACCEPT OR PICKUP PORTSMOUTH NH 03801.

</TrackDetail></TrackInfo></TrackResponse>

no problem getting the ID from the attribute or the track summary, but I can't seem to get all the trackDetails, I get the first one, but never any of the others. I don't do much xml parsing and normally I just use serialization. So this is proving problematic for me.

some Code i have tried

using (XmlReader reader = XmlReader.Create(new StringReader(e.Result)))
  {
                reader.MoveToContent();

                    while (reader.Read())
                    {
                        if (reader.IsStartElement())
                        {
                            switch (reader.Name)
                            {
                                
                                case "TrackInfo":
                                    reader.MoveToFirstAttribute();
                                    Pack.PackageID = reader.Value;
                                    break;


                                case "TrackSummary":
                                    Pack.TrackingSummary = reader.ReadElementContentAsString();
                                    break;

                                case "TrackDetail":
                                    Pack.TrackingDetails.Add(new TrackingDetail(reader.ReadElementContentAsString()));
                                    break;

                                default:
                                    reader.Skip();
                                    break;
                            }
                        }

                    }

or

using (XmlReader reader = XmlReader.Create(new StringReader(e.Result)))
  {
                    while (reader.Read())
                    {
                        if (reader.NodeType == XmlNodeType.Element)
                        {
                            if (reader.Name == "TrackInfo")
                            {
                                reader.MoveToFirstAttribute();
                                Pack.PackageID = reader.Value;
                            }
                            else if (reader.Name == "TrackSummary")
                            {
                                Pack.TrackingSummary = reader.ReadElementContentAsString();
                            }
                            else if (reader.Name == "TrackDetail")
                            {
                                Pack.TrackingDetails.Add(new TrackingDetail(reader.ReadElementContentAsString()));
                            }
                        }
                    }
}

even tried

using (XmlReader reader = XmlReader.Create(new StringReader(e.Result)))
  {
                        reader.ReadToFollowing("TrackInfo");
                    reader.MoveToFirstAttribute();
                    Pack.PackageID = reader.Value;

                    reader.ReadToFollowing("TrackSummary");
                    Pack.TrackingSummary = reader.ReadElementContentAsString();

                    while (reader.ReadToNextSibling("TrackDetail"))
                    {
                        Pack.TrackingDetails.Add(new TrackingDetail(reader.ReadElementContentAsString()));
                    }
  }

all of them run without error, showing the tracking summary, the ID and 1 of the 3 trackdetails, But none of them show all three, and not knowing how many may be there, its important that all of them are there.

So what am I doing wrong?

note: Pack is just an instance of a class that holds all the data as strings.

turns out I can serialize, in the schema I needed maxOccurs="unbounded" and now everything works fine. Visual Studio has a nice Schema generator built into, I guess I should have looked there first :)

XSD.exe still used to generate the classes though.

Thanks
