Devin Rader
I am trying to load some XML from a WebDAV query into a dataset but keep
getting an Invalid URI exception. Heres the code:

StreamReader IStream = new
StreamReader(r.GetResponseStream(),System.Text.Encoding.ASCII);
if (IStream.Peek() > 0)

ds.ReadXml(IStream.ReadToEnd(),System.Data.XmlReadMode.InferSchema);

Any ideas why?

Thanks

Devin

Don't suppose you could show us the code that builds the "r" object?
My experience with that exception is that it was not a fully-formed URI.

No Problem...

Heres most of the code in the Method:

     HttpWebRequest w = (HttpWebRequest)WebRequest.Create(strURL);
w.Credentials=new System.Net.NetworkCredential("User", "Password",
"DMA");
w.Method="SEARCH";
w.ContentType="text/xml";
w.ContentLength = System.Text.Encoding.ASCII.GetChars(tmp).Length;

     StreamWriter s = new
StreamWriter(w.GetRequestStream(),System.Text.Encoding.ASCII);
s.Write(System.Text.Encoding.ASCII.GetChars(tmp));
s.Flush();
s.Close();

w.Accept HttpContext.Current.Request.ServerVariables["HTTP_ACCEPT"];
w.Headers["Accept-Language"] HttpContext.Current.Request.ServerVariables["HTTP_ACCEPT_LANGUAGE"];
w.Headers.Add("depth","0");

w.Headers.Add("translate", "f");
w.Headers["Accept-Encoding"] HttpContext.Current.Request.ServerVariables["HTTP_ACCEPT_ENCODING"];
w.UserAgent HttpContext.Current.Request.ServerVariables["HTTP_USER_AGENT"];

try
{
HttpWebResponse r = (HttpWebResponse)w.GetResponse();

StreamReader IStream = new
StreamReader(r.GetResponseStream(),System.Text.Encoding.ASCII);

ds.ReadXml(IStream.ReadToEnd(),System.Data.XmlReadMode.InferSchema);
}
catch (Exception exc)
{}

You can see that the XML is begin returned from a HttpWebRequest via an
HttpWebResponse object, and is then loaded into an StreamReader.

I have been able to create a new XmlDocument object and load the XML into
that, but I really wanted to load it into a DataSet, rather then having to
work with the DOM.

The XML returned from the WebDAV request looks like this:

<?xml version="1.0"?>
<a:multistatus xmlns:b="urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/"
xmlns:c="xml:" xmlns:d="urn:schemas-microsoft-com:office:office"

Little, Ambrose
Devin,

My experience with this error is that it has a not-fully-formed URI. For
instance, if I pass a relative URL to it, it blows up. Make sure you're
passing the full URL, e.g., http://www.mysite.com/mydir/mypage.aspx
<http://www.mysite.com/mydir/mypage.aspx> .

After more experimenting, I have found that if I save the response XML to a
file, then load the DS from that file, it works.

Heres the code:

xmlDocBack.LoadXml(IStream.ReadToEnd()); //<-- Save XML TO FILE
xmlDocBack.Save("c:\\inetpub\\wwwroot\\WebDAV-WebAPP\\XMLFile3.xml");

DataSet ds = new DataSet(); //<-- LOAD XML FROM SAME FILE INTO DS
ds.ReadXml("c:\\inetpub\\wwwroot\\WebDAV-WebAPP\\XMLFile3.xml");

dgResults.DataSource = ds.Tables;
dgResults.DataBind();

Why can I not go straight to the DS without having to save?

Is there anyone out there?

Thanks!!

Devin
