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
        }
    }
}
