c# read XML file not correctly formatted

Question

I have to read an XML file, that has no root element, to extract contained data. The XML has many elements like these:

Answer 1

You xml is simply not well formed which often happens when xml data is merged together. Your xml has multiple tags at root level so use XML reader like below :

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


namespace ConsoleApplication4
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XmlReaderSettings settings = new XmlReaderSettings();
            settings.ConformanceLevel = ConformanceLevel.Fragment;
            XmlReader reader = XmlReader.Create(FILENAME,settings);
            while (!reader.EOF)
            {
                try
                {
                    if (reader.Name != "LOG_x0020_ParityRate")
                    {
                        reader.ReadToFollowing("LOG_x0020_ParityRate");
                    }
                    if (!reader.EOF)
                    {
                        XElement parityRate = (XElement)XElement.ReadFrom(reader);

                        ParityRate newLog = new ParityRate();
                        ParityRate.logs.Add(newLog);
                        newLog.date = DateTime.ParseExact((string)parityRate.Element("DATE"), "MM/dd/yyyy - hh:mm", System.Globalization.CultureInfo.InvariantCulture);
                        newLog.name = (string)parityRate.Element("CHANNELNAME");
                        newLog.sql = (string)parityRate.Element("SQL");
                        newLog.hotel = (int)parityRate.Element("ID_HOTEL");
                    }
                }
                catch (Exception ex)
                {
                }
            }
        }
    }
    public class ParityRate
    {
        public static List<ParityRate> logs = new List<ParityRate>();

        public DateTime date { get; set; }
        public string name { get; set; }
        public string sql { get; set; }
        public int hotel { get; set; }
    }
}

Answer 2

You can try to use XmlParser:

A Roslyn-inspired full-fidelity XML parser with no dependencies and a simple Visual Studio XML language service.

It pars any bad formed xml.

Answer 3

I found a way to solve my problem, I gave up to read it as an XML and I read it as a StreamReader, looking for the text I want to read, so I don't have to fight against the XML format

using (StreamReader strReader = File.OpenText(path))
            {
                while (!strReader.EndOfStream)
                {
                    string line = strReader.ReadLine();
                    if (line.Contains("<LOG_x0020_ParityRate>")) {
                        line = strReader.ReadLine();
                        string data_ = getTagText(line);
                        string channelName_ = getTagText( strReader.ReadLine());
                        string sql_ = getTagText( strReader.ReadLine());
                        string idHotel_ = getTagText(strReader.ReadLine());
                        string type_ = getTagText(strReader.ReadLine());


                    }


                }
            }
