Parsing XML file using C#?

Question

I\'m new to both XML and C#; I\'m trying to find a way to efficiently parse a given xml file to retrieve relevant numerical values, base on the \"proj_title\" value=heat_run or

8MB really isn't very large at all by modern standards. Personally I'd use LINQ to XML:

XDocument doc = XDocument.Load("ex.xml");
var projects = doc.Descendants("proj_title")
                  .Where(x => (string) x == "heat_run")
                  .Select(x => x.Parent) // Just for simplicity
                  .Select(x => new {
                              Start = (int) x.Element("proj_start"),
                              End = (int) x.Element("proj_end")
                          });

foreach (var project in projects)
{
    Console.WriteLine("Start: {0}; End: {1}", project.Start, project.End);
}

(Obviously adjust this to your own requirements - it's not really clear what you need to do based on the question.)

Alternative query:

var projects = doc.Descendants("proj")
                  .Where(x => (string) x.Element("proj_title") == "heat_run")
                  .Select(x => new {
                              Start = (int) x.Element("proj_start"),
                              End = (int) x.Element("proj_end")
                          });
