递归/动态地将XML属性添加到单个动态对象中

Question

So i have an XML document that has multiple tiers like this:

<root>
<Client id='1' name='bob'>
     <health id='1'>
          <ex id='2'\>
          <ex id='3' \>
     </health>
</Client>
<Client id='1' name='bob'>
     <health id='1'>
          <ex id='2'\>
          <ex id='3' \>
     </health>
</Client>
</root>

I am trying to recursively go through the XML document and each attribute to an ExpandoObject and add all sub nodes into an ExpandoObject recursively. So the end result of the above xml would have an ExpandoObject with client attributes and also an ExpandoObject inside of it with attributes of health and 2 expandoObjects with their 'ex' attributes in the health ExpandoObject. So its like putting an XML document inside of a multidimensional Dictionary aka an ExpandoObject.

I am having a lot of trouble with the recursion its confusing me hardcore and I can't seem to get it working. Does anyone know how I can traverse like an XDocument recursively and add an ExpandoObject to itself for every sublevel but if its the same depth level add multiple ExpandoObjects to the object above it?

I know this might confuse you since I am also confused but the end object should look something like this:

Object asd = [Properties of Client] + (ExpandoObject asd2 = [properties of health] + (ExpandoObject asd3 = properties of ex + ExpandoObject asd4 = properties of ex2)

I found some code that has been working for me so far.

 public static class XmlDocumentExtension
{
    public static dynamic ToObject(this XmlDocument document)
    {
        XmlElement root = document.DocumentElement;
        return ToObject(root, new ExpandoObject());
    }

    private static dynamic ToObject(XmlNode node, ExpandoObject config, int count = 1)
    {
        var parent = config as IDictionary<string, object>;
        foreach (XmlAttribute nodeAttribute in node.Attributes)
        {
            var nodeAttrName = nodeAttribute.Name.ToString();
            parent[nodeAttrName] = nodeAttribute.Value;
        }
        foreach (XmlNode nodeChild in node.ChildNodes)
        {
            if (IsTextOrCDataSection(nodeChild))
            {
                parent["Value"] = nodeChild.Value;
            }
            else
            {
                string nodeChildName = nodeChild.Name.ToString();
                if (parent.ContainsKey(nodeChildName))
                {
                    parent[nodeChildName + "_" + count] = ToObject(nodeChild, new ExpandoObject(), count++);
                }
                else
                {
                    parent[nodeChildName] = ToObject(nodeChild, new ExpandoObject());
                }
            }
        }
        return config;
    }

    private static bool IsTextOrCDataSection(XmlNode node)
    {
        return node.Name == "#text" || node.Name == "#cdata-section";
    }
}

i think looping this will help you (change 'this' to object of a class that you want to set its properties from xml attributes) :

public void AddXElementAttributesToThisClass(XElement xe)
        {
            ExpandoObject obj = new ExpandoObject();
            foreach (var attribute in xe.Attributes())
            {
                 (obj as IDictionary<string, object>)[attribute.Name.ToString()] = attribute.Value.Trim();
            }
            var dynamicDictionary = obj as IDictionary<string, object>;
            foreach (var property in this.GetType().GetProperties())
            {
                var propName = property.Name;
                var value = property.GetValue(this, null);
                if (dynamicDictionary.ContainsKey(propName) && value != dynamicDictionary[propName])
                {
                    var foundXmlObj= dynamicDictionary[propName];
                    property.SetValue(this, foundXmlObj);
                }
            }
        }
