I have got this line of code to get all files of Xml that are downloaded on my server

C#

string[] fileEntries = Directory.GetFiles(Server.MapPath("~/SavedFolder/" +  Session["Username"].ToString() + "//"));

currently i am using XmlDocument to load each file name in the file entries
i want a faster way to read these Xml any suggestion how can i use Xml Reader or any other Xml tool .

What I have tried:

currently i am using

C#

    string[] fileEntries = Directory.GetFiles(Server.MapPath("~/SavedFolder/" +  Session["Username"].ToString() + "//"));

foreach(string fileName in fileEntries)
 {

  XmlDocument xml = new XmlDocument();
  xml.Load(@fileName)
 }

How slow are we talking here?
What have you measured it as taking?
How often is this done?
How many files?

Himaan Singh 18-May-16 5:39am

files are around 100 each of 1 mb each

Are you only reading the files or do something else with that XML you just read in? Did you broke apart the time, to see if it spent on the reading part or on the processing part?

what i do is read different nodes from the xml and store that information in a list

That's only partly answers my question - what about the timing?

Himaan Singh 18-May-16 5:49am

i guess the processing time is more

Himaan Singh 18-May-16 5:50am

cause it has nodes that has huge data

Makes sense to me - but it means, that you have to focus on that part instead of wasting your time about how to read an XML file...

Go through the extensive documentation for XmlReader and concert your code to us it and see if it helps speed things up.

You need to be more specific about how long it currently takes, and how long you want it to take. Readers are faster for sure but are also more difficult, but you could probably go parallel to speed things up with minimum effort.

Maybe something like this, you can select the nodes that are needed this way:

C#

using (var xmlTextReader = new XmlTextReader(fileNameXml))
{
    while (xmlTextReader.Read())
    {
        switch (xmlTextReader.NodeType)
        {
            case XmlNodeType.Element: // The node is an element (group).
                Debug.Print(@"<" + xmlTextReader.Name + @">");
                break;

            case XmlNodeType.Text:

                Debug.Print(xmlTextReader.Value);
                break;

            case XmlNodeType.EndElement: // Display the end of the element.
                Debug.Print(@"</" + xmlTextReader.Name + @">");
                break;
        }
    }
}
