Parse xml from request.file without saving in server

Question

I upload an xml file through $.ajax post as formdata to an mvc controller. Is it possible to parse the file without it being saved in some directory in the server. My c# code is as below

        [HttpPost]
        public ActionResult VersionXML()
        {
            if (Request.Files.Count > 0)
            {
                var file = Request.Files[0];
                /*--Can I exempt this if clause and do something for the parsing--*/
                if (file != null && file.ContentLength > 0)
                {
                    var fileName = Path.GetFileName(file.FileName);
                    var path = Path.Combine(Server.MapPath("~/Uploads/"), fileName);
                    file.SaveAs(path);
                }
            }

            return RedirectToAction("Show_New_Content");
        }

Looks like duplicate of this. https://stackoverflow.com/questions/34116791/reading-uploaded-excel-file-without-saving-it — Bijay Yadav, Feb 07 '19 at 06:30

You have two options to parse with XML

1) You can load InputStream of your file to XmlDocument directly and process your xml,

if (file != null && file.ContentLength > 0 && file.ContentType == "text/xml")
{
    XmlDocument xdoc = new XmlDocument();
    xdoc.Load(file.InputStream);

    //You can parse your xml here

    //Upload file code here       
}

2) You can also load InputStream of your file to XDocument,

if (file != null && file.ContentLength > 0 && file.ContentType == "text/xml")
{
    XDocument doc = XDocument.Load(new StreamReader(file.InputStream));

    //You can parse your xml here

    //Upload file code here       
}

With `XDocument` you can use Linq on it and `XmlDocument` you can parse your xml in traditional. – er-sho Feb 07 '19 at 06:56
