I have problems with deserializing XML to the List of locations objects.
Given the following XML:
<?xml version="1.0" encoding="utf-8"?>
<locations>
<location id="1">
<level name="3" complete="True" stars="1" firstMisson="True" secondMission="False" thridMission="False" />
</location>
<location id="2">
<level name="4" complete="True" stars="3" firstMisson="True" secondMission="True" thridMission="True" />
</location>
</locations>
And the following class:
[System.Serializable]
[XmlRoot(ElementName = "level")]
public class Level
{
[XmlAttribute(AttributeName = "name")]
public string Name { get; set; }
[XmlAttribute(AttributeName = "complete")]
public string Complete { get; set; }
[XmlAttribute(AttributeName = "stars")]
public string Stars { get; set; }
[XmlAttribute(AttributeName = "firstMisson")]
public string FirstMisson { get; set; }
[XmlAttribute(AttributeName = "secondMission")]
public string SecondMission { get; set; }
[XmlAttribute(AttributeName = "thridMission")]
public string ThridMission { get; set; }
}
[System.Serializable]
[XmlRoot(ElementName = "location")]
public class Location
{
[XmlElement(ElementName = "level")]
public Level Level { get; set; }
[XmlAttribute(AttributeName = "id")]
public string Id { get; set; }
}
[System.Serializable]
[XmlRoot(ElementName = "locations")]
public class Locations
{
[XmlElement(ElementName = "location")]
public Location Location { get; set; }
public List<Locations> LocDb = new List<Locations>();
}
[System.Serializable]
[XmlRoot(ElementName = "xml")]
public class Xml
{
[XmlElement(ElementName = "locations")]
public Locations Locations { get; set; }
}
Deserialization Method
public List<Locations> locDB = new List<Locations>();
public static void LoadData()
{
string filepath = Application.dataPath + @"/XML/GameXMLdata.xml";
var xmlSerializer = new XmlSerializer(locDB.GetType());
var stream = File.Open(filepath, FileMode.Open);
locDB = (List<Locations>)xmlSerializer.Deserialize(stream);//locations xmlns=''> was not expected
stream.Close();
Debug.Log(locDB[1].Location.Id);
}
So how do I deserialize XML to List of location objects?
Many thanks for help.
You need only two classes:
[XmlType("level")]
public class Level
{
[XmlAttribute("name")]
public string Name { get; set; }
[XmlAttribute("complete")]
public string Complete { get; set; }
[XmlAttribute("stars")]
public string Stars { get; set; }
[XmlAttribute("firstMisson")]
public string FirstMisson { get; set; }
[XmlAttribute("secondMission")]
public string SecondMission { get; set; }
[XmlAttribute("thridMission")]
public string ThridMission { get; set; }
}
[XmlType("location")]
public class Location
{
[XmlElement("level")]
public Level Level { get; set; }
[XmlAttribute("id")]
public string Id { get; set; }
}
The important is to apply XmlType
attribute to the class Location
rather than XmlRoot
.
Now you can deserialize your XML to List<Location>
like this:
var xmlSerializer = new XmlSerializer(typeof(List<Location>),
new XmlRootAttribute("locations"));
List<Location> locations;
using (var stream = File.OpenRead(filepath))
locations = (List<Location>)xmlSerializer.Deserialize(stream);
The trick is to specify the root element name ("locations" in your case) using the XmlSerializer(Type, XmlRootAttribute)
constructor overload.
I had a similar problem on a class property and solved it using a different approach. Since in my scenario I wasn't able to touch the XmlSerializer
construction logic, this is what I did (using the types from OP for reference):
[XmlRoot("locations")]
public sealed class LocationCollection : Collection<Location>
{
}
With the custom collection class, I'm able to set the root at design time and still use a standard XmlSeriaizer
instance.
