response object assistance with returning xml.

Martin Dew

I have a page which upon opening gets information from a database, the field
it returns has structured xml stored in it.

private void Page_Load(object sender, System.EventArgs e)

{

if (!IsPostBack) {

GetRecordFromServer(this.Request.QueryString[0].ToString());

}

}

private void GetRecordFromServer(string searchID) {
DataSet ds = dbAuditLog.GetEntry(new Guid(searchID));

DataTable dt = ds.Tables[0];
Response.ContentType = "Text/XML";

Response.Output.Write(dt.Rows[0]["XMLText"].ToString());
}

The problem I am having is that the resulting page does not quite display
properly, it always seems to add the following to the end of the xml, I just
want the xml from my field to be streamed to the response, and that is all,
can anyone help ?

You need to rip everything (well almost everything) out of your aspx file;

For example;

<%@ Page language="c#" Codebehind="DisplayXML.aspx.cs"
AutoEventWireup="false" Inherits="YourNamespace.DisplayXML" %>

I also have an application that returns Xml to the user. I actually use
"text/plain" as the content type, but that's because the user will likely
need to copy and paste the Xml and if I use "text/xml" then IE hides the Xml
tags and only displays the text.

But anyway, try this before you write to the stream:

HttpContext context = HttpContext.Current;
context.Response.Clear();
context.Response.ContentType = "text/xml";

Or more simply :
Response.Clear();
Response.ContentType = "text/xml";

The first is what I have in my code and both snippets should be the same,
but it's just what I wrote at the time, I don't remember why I chose that
method.

Regards,
Mark

Hello Martin,

Make sure you do a Response.End() after the XML is written out. This stops
the processing of the current response.
