Troubleshooting Reading XML

Unity Engine
1

After following several tutorials I almost have my code working just the way I want, however when I call the load function it doesn’t appear to be correctly parsing the XML document (even though it acquires it) and returns a container of 0 items. Can anyone suggest how to amend my code?

Thanks!

The saving function works, but the load function returns a LeaderContainer of size 0 no matter what document it acquires.

using System.Collections;
using System.Collections.Generic;
using System.Xml.Serialization;
using System.Xml;
using System.IO;
using UnityEngine;

[XmlRoot("leaders")]
public class LeaderContainer {

    [XmlArray("Leaders"), XmlArrayItem("Leader")]
    public List<MemoryManager.Leader> leaders = new List<MemoryManager.Leader>();


    public void Save(string path)
    {
        var serializer = new XmlSerializer(typeof(LeaderContainer));

        using (var stream = new FileStream(path, FileMode.Create))
        {
            serializer.Serialize(stream, this);
        }
    }


    public static LeaderContainer Load(string path)
    {
        Debug.Log("Loading " + path);
        TextAsset _xml = Resources.Load<TextAsset>(path);

        XmlSerializer serializer = new XmlSerializer(typeof(LeaderContainer));

        StringReader reader = new StringReader(_xml.text);

        LeaderContainer l = serializer.Deserialize(reader) as LeaderContainer;

        reader.Close();

        Debug.Log(l.rosterSize());

        return l;
    }

    public static LeaderContainer LoadFromText(string text)
    {
        var serializer = new XmlSerializer(typeof(LeaderContainer));
        return serializer.Deserialize(new StringReader(text)) as LeaderContainer;
    }

    public int rosterSize()
    {
        int size = 0;
        foreach (MemoryManager.Leader l in leaders)
        {
            size++;
        }
        return size;
    }

}

Your code works for me. How are you calling Save and Load? What does MemoryManager.Leader look like? Does the XML contain what you expect after Save is called?

Leader is an xml class and memory manager initializes a leader2 class that inherits monobehavior and iterates over the data in leader2 assigning it from the leader xml class.

The problem is before I even get to that it is reporting that my saved LeaderContainer (above), which is supposed to contain a list of leaders loaded from the xml, contains an empty list of leaders.

I’ll post some sample code asap.
