How to convert xml to style so that browser can render html from xml when using RSS

Question

I have downloaded a app called MessageBoard and trying to configure RSS Feed to output serialised data to browser. The result display a error message with code written in xml format.

This XML file does not appear to have any style information associated with it.

Therefore How do i setup and add such a file ?

The method

        Public Function GetLatestMessages(ByVal format As FeedFormat) As SyndicationFeedFormatter Implements IFeedService.GetLatestMessages
            Dim rootUri As Uri = GetRootUri(
                       Dim feed As SyndicationFeed = New SyndicationFeed("Message Board", "A sample message board built using Visual Studio 2008.", rootUri)

               feed.Items = From m In MessageProvider.GetRecentMessages(0, 10) Select CreateSyndicationItem(m, rootUri)
          
                   

            If format = FeedFormat.Atom Then Return New Atom10FeedFormatter(feed)
            Return New Rss20FeedFormatter(feed)
         
        End Function


        Private Function CreateSyndicationItem(ByVal m As Message, ByVal rootUri As Uri) As SyndicationItem
          
            Dim uriBuilder As UriBuilder = New UriBuilder(rootUri)
            uriBuilder.Path += "/Message.aspx"
            uriBuilder.Query = "id=" & m.topicId.ToString(CultureInfo.InvariantCulture)

      
            'The Syndic
            Dim item = New SyndicationItem(m.TopicSubject,
                                           m.TopicBody,
                                           uriBuilder.Uri,
                                           m.topicId.ToString(),
                                           New DateTimeOffset(m.topiccreateDate, New New TimeSpan(0)))
           
     
  Return item
        End Function

Dim rssWriter As XmlWriter = XmlWriter.Create("rss.xml")

        rssWriter.WriteProcessingInstruction("xml-stylesheet",

                                             "type='text/xsl' href='XSLTFile.xslt'")

        Dim rssFormatter As Rss20FeedFormatter = New Rss20FeedFormatter(feed)

        rssFormatter.WriteTo(rssWriter)

        rssWriter.Close()

        Return rssFormatter

The system returns a request error message:

The server encountered an error processing the request. The exception message is 'Access to the path 'C:\Program Files (x86)\IIS Express\rss.xml' is denied.'. See server logs for more details.

The stack trace ends at first line shows.so i assume that the feed is readonly ?

so how may i edit the file to write the xls sheet address and then return edited version as shown on original question.

I wish there was a working example of rss.

Answer 2

The code block below is the experimental XML content that is produced. I eventually managed to obtain reference to XSLT file. I am not familiar with both sets of languages to create the XSLT style sheet.

Is there a way to quickly transform from one type to another?

Answer 4

I have created a XSLT file and attempted to attach to the rss XML file as generated from my RSS method.

using the following code:

 Dim rssWriter As XmlWriter = XmlWriter.Create("rss.xml")
            rssWriter.WriteProcessingInstruction("xml-stylesheet",
                                                 "type='text/xsl' href='XSLTFile.xslt'")
            Dim rssFormatter As Rss20FeedFormatter = New Rss20FeedFormatter(feed)
            rssFormatter.WriteTo(rssWriter)
            rssWriter.Close()
            Return rssFormatter

The system returns a request error message:
The server encountered an error processing the request. The exception message is 'Access to the path 'C:\Program Files (x86)\IIS Express\rss.xml' is denied.'. See server logs for more details.
The stack trace ends at first line shows.so i assume that the feed is readonly ? 
so how may i edit the file to write the xls sheet address and then return edited version as shown on original question.
I wish there was a working example of rss.

the system warns me that i need admin permission to change IIS Express folder access. Is this a windows login routine or sql server ?
