Response.Write() rss xml

[John A Grandy]

When writing rss xml to the client browser , is there any reason to load the
rss xml string into an XmlDocument and then Response.Write( ) the
XmlDocument.Out erXML.ToString( ) ?

option 1:

string rssXml = null;
-- build rssXML --
Response.Write( rssXml);

option 2:
string rssXml = null;
-- build rssXML --
XmlDocument xmlDoc = new XmlDocument;
xmlDoc.Load(rss Xml);
Response.Write( xmlDoc.OuterXml .ToString());

Why would you want to load into XmlDocument first to then Response.Write
the OuterXml?
I think what you want to do is use an XmlTextWriter to create and write
the XML to the HTTP response e.g.

<%@ Page Language="C#" %>
<%@ Import Namespace="Syst em.Xml" %>
<script runat="server">
void Page_Load () {
Response.Conten tType = "applicatio n/xml";
XmlTextWriter xmlWriter = new XmlTextWriter(R esponse.Output) ;
xmlWriter.Write StartDocument() ;
xmlWriter.Write StartElement("g ods");
xmlWriter.Write ElementString(" god", "Kibo");
xmlWriter.Write ElementString(" god", "Xibo");
xmlWriter.Write EndDocument();
xmlWriter.Close ();
}
</script>

Don't build the RSS/XML as a text string, instead make use of
XmlTextWriter which takes care of escaping characters and other
well-formedness constraints.

Re:

XmlTextWriter xmlWriter = new XmlTextWriter(R esponse.Output) ;
xmlWriter.Close ();

How do you send the XMLTextWriter contents to the client browser ( assuming
you only want to send xml to the client browser ) ?

Don't you have to call XMLTextWriter.F lush() before you cal
XMLTextWriter.C lose() ?

Or does the Page.Render() event handler still need to be overriden ?
Something like Response.Write( XMLTextWriter.{ some method} )

By creating the XmlTextWriter over Response.Output
new XmlTextWriter(R esponse.Output)
