Abstracting data in a txt file

matthew king

Sir/Ma'am

I'm hoping someone could point me in the right direction. I'm attempting to read a txt file via c# and obtain specific information. The data is constructed in a.txt file in the following manner: . . I'm trying to read the txt file line by line and isolated the values within Automobile id=" ", so I can append them to a richtextbox. Ultimately, I'm trying to populate a richtextbox with all the Automobile ids within the given text file (e.g. Chevy1 Ford22 ford18 dodge1). Any help you can provide would be appreciated!

This is a suitable problem to solve using regular expressions.

Here's some code (using console app for testing purposes). I'm assuming that there's actually a 'dot' after each closing '>' :

using System;
using System.IO;
using System.Text.RegularExpressions;

class Test
{
   static void Main()
   {
   string text = File.ReadAllText("king.txt");
   string regExp = @"(?<=\.)";
   MatchCollection matches = Regex.Matches(text, regExp);
   foreach(Match m in matches) Console.WriteLine(m.Value);
   Console.ReadKey();
   }
}

That data looks like XML. Are you familiar with XML? There are many articles in this web site about XML. If it is XML then it will be more reliable to read the data as XML.
