Recursive function to going through each embedded schema field in a schema to reach a leaf data field - tridion

Question

I have a schema in Tridion which have embedded schema fields which may further have embedded fields in there.
I want to reach final leaf field so that I can assign some value to it. For that I want to write recursive function which loop through each and every field until it reaches a final field.
I am implementing using the Core Service in SDL Tridion 2011
My code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.ServiceModel;
using System.Net;
using System.Xml;
using Tridion.ContentManager.CoreService.Client;
using System.Text;
using Tridion.ContentManager.CoreService;
using System.ServiceModel.Channels;
using System.IO;
using System.Collections;
using System.Text.RegularExpressions;
using System.Xml.Linq;
using System.Data.OleDb;
using System.Data;
using System.Configuration;
namespace Loading_Utility
{
public partial class TST : System.Web.UI.Page
{
Fields obj = new Fields();
protected void Page_Load(object sender, EventArgs e)
{
using (ChannelFactory<ISessionAwareCoreService> factory =
new ChannelFactory<ISessionAwareCoreService>("wsHttp_2011"))
{
ISessionAwareCoreService client = factory.CreateChannel();
var schemaFields = client.ReadSchemaFields("tcm:202-2242-8", true, new ReadOptions());
ComponentData component = (ComponentData)client.GetDefaultData(ItemType.Component, "tcm:202-638-2");
var fields = Fields.ForContentOf(schemaFields);
component.Schema.IdRef="tcm:202-2242-8";
}
}
public void fieldRecursion(Field field)
{
//var getFields = fields;
if (field.GetType() == typeof(EmbeddedSchemaFieldDefinitionData))
{
// code for checking further if field is embedded or not
//Field newField = field.GetSubFields().GetFieldElements( new ItemFieldDefinitionData() as Field)
//fieldRecursion(recursiveField);
}
//string fieldName = recursiveField.Name;
//fields[fieldName] = "HI";
}
}
}

Whilst I don't have the solution you are looking for, I see you're using the core service, personally I prefer to get hold of the Component XML (Component.Content) and parse/manipulate it as I need. Perhaps if you can paste the XML here I can drop it into one of my sample core service projects and send you a solution back?
In the event that doesn't help you, i've had a look at the api, and this should help you get going in the right path. Perhaps once you have a solution you could paste it here?
public void RecurseEmbeddedFields(SchemaFieldsData schemaFields)
{
foreach (ItemFieldDefinitionData field in schemaFields.Fields)
{
if (field.GetType() == typeof(EmbeddedSchemaFieldDefinitionData))
{
// check if this field contains more embedded fields
// if it does recurse
}
}
}

OK, I felt a bit guilty about not helping, but I still stand by my view that this is not a Tridion-related question and that you should try getting some more experience with general development practices.
Here's an example of how to load the Component's content, then read it recursively using Xml:
Xml of the component:
<Content xmlns="uuid:02395f72-acef-44e8-9c35-ff8c9f380251">
<EmbeddedSchema1>
<SomeField>Hello</SomeField>
<EmbeddedSchema2>
<ATextField>There</ATextField>
</EmbeddedSchema2>
</EmbeddedSchema1>
</Content>
Core Service code:
static void Main(string[] args)
{
SessionAwareCoreServiceClient client = new SessionAwareCoreServiceClient("wsHttp_2011");
ReadOptions readOptions = new ReadOptions();
ComponentData component = (ComponentData)client.Read("tcm:5-3234", readOptions);
Console.WriteLine("Find fields recursively");
XmlDocument content = new XmlDocument();
content.LoadXml(component.Content);
SchemaData schema = (SchemaData)client.Read(component.Schema.IdRef, readOptions);
XmlNamespaceManager ns = new XmlNamespaceManager(new NameTable());
ns.AddNamespace("content", schema.NamespaceUri);
foreach (XmlElement node in content.SelectNodes("content:*", ns))
{
ReadContentRecursively(node, ns);
}
client.Close();
}
private static void ReadContentRecursively(XmlElement node, XmlNamespaceManager ns)
{
if(!string.IsNullOrEmpty(node.InnerText))
{
foreach (XmlNode innerNode in node)
{
if(innerNode is XmlText)
{
Console.WriteLine("Node " + node.Name + " with value \"" + innerNode.Value + "\"");
}
}
}
if(node.SelectNodes("content:*", ns).Count > 0)
{
foreach (XmlElement childNode in node.SelectNodes("content:*", ns))
{
Console.WriteLine("Found Field: " + childNode.Name);
ReadContentRecursively(childNode, ns);
}
}
}
Notice how ReadContentRecursively calls itself?
Hope this helps.
