With things like this, C# is regaining my attention. Parse a simple XML to a string array containing only the child elements defined in an other string array:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml.Linq;

namespace PruebaLinqFuncional
{
    class Program
    {
        public static List ParseXML(string xml, string objectName, string[] dataToParse)
        {
            //Programacion funcional en C# :O

            /*
            return XDocument.Parse(xml).Descendants(objectName).Select((element) =>
            {
                var lst = new List();
                foreach (string field in dataToParse)
                    lst.Add(element.Element(field).Value);
                return lst.ToArray();
            }).ToList();
             */

            return XDocument.Parse(xml).Descendants(objectName).Select( (element) =>
            {
                return dataToParse.Select( (field) => 
                { 
                    return element.Element(field).Value; 
                }).ToArray();
            }).ToList();
        }

        static void Main(string[] args)
        {
            var xml = @"

  string-value
  string-value
  int-value
  string-value
  
    
      Mi_URL_Uno
      Mi_Blob_Uno
      date/time-value
      etag
      size-in-bytes
      blob-content-type
      
      
    
    
      Mi_URL_Dos
      Mi_Blob_Dos
      date/time-value
      etag
      size-in-bytes
      blob-content-type
      
      
    
  
  
    blob-prefix
  
  
";


            foreach (var stra in ParseXML(xml, "Blob", new string[] { "Url", "Name" }))
                Console.WriteLine(string.Join(",", stra));

            Console.ReadLine();
        }
    }
}
