I am having problems loading xml stored as a blob in an Oracle
database.

I am getting the following error trying to display the xml object on
the page:

Server Error in '/PostFunding/Web' Application.

The UNC path should be of the form \\server\share.

Here is what I think are the relevant parts of the code:

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

namespace Web.Secondary.Pretell
{
public class DisplayBlob : System.Web.UI.Page
{
protected System.Web.UI.WebControls.Xml Xml1;

private void Page_Load(object sender, System.EventArgs e)
{
code to get the blob works and is removed from here for
brevity...
DisplayTheBlob(blob);
}

private void DisplayTheBlob(byte[] blob)
{
try
{
System.IO.MemoryStream ms = new System.IO.MemoryStream();
ms.Write(blob, 0, blob.Length);
ms.Flush();
System.Xml.XmlDocument xdoc = new System.Xml.XmlDocument();

xdoc.Load("C:\\prf_blob.xml"); //UNC PATH ERROR HERE

// Create an XPathNavigator to use for the transform.
System.Xml.XPath.XPathNavigator nav =
xdoc.DocumentElement.CreateNavigator();
System.Xml.Xsl.XslTransform xsl = new
System.Xml.Xsl.XslTransform();
xsl.Load("C:\\FREDDIE\\FullFeedback_v3.0.xsl");
System.Xml.XmlTextWriter writer = new
System.Xml.XmlTextWriter("\\junk.xml", Encoding.UTF8);
xsl.Transform(nav, null, writer, null);
writer.Close();
Xml1.Transform = xsl;
Xml1.Document = xdoc;
}
catch (Exception e)
{
throw new Exception("blob exception" , e);
}
}

Here are the first few lines of the prf_blob.xml file:

<?xml version="1.0" ?><!DOCTYPE SERVICE_ORDER_RESPONSE SYSTEM "file:///
LOANPROSPECTOR_RESPONSE.3.0.DTD"><SERVICE_ORDER_RESPONSE
_Date="03-09-2007">
<KEY _Name="LOANPROSPECTOR_REQUEST" _Value="3.0"/>
<KEY _Name="LOANPROSPECTOR_RESPONSE" _Value="3.0"/>
<STATUS _Processing="Completed"/>

If I remove 'SYSTEM "file:///LOANPROSPECTOR_RESPONSE.3.0.DTD"' it
works as expected and displays the page in all of its multi-hued
glory :).

From everthing that I have been able to ascertain this is valid UNC

path syntax. Can anyone help me resolve this or explain why it is
being interpreted as invalid?

Removing 'SYSTEM "file:///LOANPROSPECTOR_RESPONSE.3.0.DTD"' from the
database blob is not an option for us since it is used extensively
across the enterprise outside of my .NET app.

If I can provide additional details to help with this, please let me
know.

TIA

Luke

I forgot to add: The location of LOANPROSPECTOR_RESPONSE.3.0.DTD is
C:\LOANPROSPECTOR_RESPONSE.3.0.DTD.
