Add support for relative paths for the rssTempDir AppSetting

From forum:
The problem is that I need to set the AppSettings to "C:\\inetpub\MyApp\Temp\Rss".
Is it possible to set it to something like this:"~\Temp\Rss".

Closed Feature: How to set multiple categories for an item [9809]

astec — Thu, 16 May 2013 09:49:40 GMT

Is it possible to set multiple categories for an item ?

i tried using:
item"category"="my category1";
item"category"="my category2";

channel.Add(item);

This way i only get "my category2" as the item's category. Am I doing something wrong?

Commented Issue: Updates Needed to Fix Support for Atom Feeds [14931]

jaydee777 — Fri, 25 May 2012 17:36:18 GMT

Symptoms when consuming Atom feeds:
- <pubDate/> is empty
- <link/> links to the <channel/> URL and not the <item/> URL

Fixes in AtomToRss20.xsl
- LINE 25: <xsl:value-of select="//*[name()='modified']"/> should be <xsl:value-of select="//*[name()='updated']"/>
- LINE 43: <xsl:value-of select="//*[name()='link']/@href"/>should be <xsl:value-of select="child::*[name()='link']/@href"/>
- LINE 55: <xsl:value-of select="//*[name()='modified']"/> should be <xsl:value-of select="//*[name()='updated']"/>

Attached is a compiled version that incorporates these changes.

The incorrect <link> tag href attribute is generated when added rsshyperlink control to the page:

<link rel="alternate" type="application/rss+xml" title="Rss" href="~/RssHyperLink.ashx" />

The cause is in RssHyperLink.cs in OnPreRender function code:

Page.Header.Controls.Add(
new LiteralControl(
string.Format(
System.Globalization.CultureInfo.InvariantCulture,
"\r\n<link rel=\"alternate\" type=\"application/rss+xml\" title=\"{0}\" href=\"{1}\" />",
title,
NavigateUrl)));

Can be fixed with the following:

Page.Header.Controls.Add(
new LiteralControl(
string.Format(
System.Globalization.CultureInfo.InvariantCulture,
"\r\n<link rel=\"alternate\" type=\"application/rss+xml\" title=\"{0}\" href=\"{1}\" />",
title,
Page.ResolveUrl(NavigateUrl))));

Good Luck,
Alex

Created Issue: AtomToRss20.xsl seemingly incorrect. Gets wrong link. [32368]

DaveA — Wed, 07 Mar 2012 11:48:05 GMT

Line 42 in \Resources\AtomToRss20.xsl is this

<xsl:element name="link">
<xsl:value-of select="//*[name()='link']/@href"/>
</xsl:element>

Surely it should be

<xsl:element name="link">
<xsl:value-of select="child::*[name()='link']/@href"/>
</xsl:element>

?

When changed the link to atom feeds point to the post's web page. Left unchanged the link to atom feeds points to the feed's url.

Thanks in advance.

Created Issue: System.ArgumentException: An XML comment cannot contain '--', and '-' cannot be the last character. [30446]

elhaix — Tue, 29 Mar 2011 19:19:20 GMT

Using the following RSS Uri: http://www.buysell.com/rss/electronics-computers/audio-video/Calgary-AB/search-rss-x/50-Calgary-AB-pf-c1-c2-a-prx-lloc--2z3acaz3acaz2bazy2ba6y-6F186C4A/

The following exception is thrown:

System.ArgumentException: An XML comment cannot contain '--', and '-' cannot be the last character. at System.Xml.XmlTextWriter.WriteComment(String text)r

In Google reader, and others, the RSS stream is readable and no exceptions seem to be thrown.

The issue lies in before these two lines, located in RssToolkit.Rss.DownloadManager.TrySaveToDisk():

XmlComment comment = doc.CreateComment(string.Format(CultureInfo.InvariantCulture, "{0}@{1}", utcExpiry.ToBinary(), url));
doc.InsertBefore(comment, doc.DocumentElement);

The URL contains "--" and thus has to be escaped before creating the XML comment, then unescaped there after.

To fix this, surround the XmlComment line with the following string replace commands:

url = url.Replace("--", "$$$$");
XmlComment comment = doc.CreateComment(string.Format(CultureInfo.InvariantCulture, "{0}@{1}", utcExpiry.ToBinary(), url));
url = url.Replace("$$$$","--");

Commented Issue: Media RSS Support [22252]

simon831 — Fri, 19 Mar 2010 10:00:13 GMT

When I try to create a Media RSS feed the output is slightly flawed. I get <content></content> tags rather than what I should get <media:content> </media:content>

About 'Media RSS', here is a helpful primer: http://www.webmonkey.com/tutorial/Use_Media_RSS

The problem I am experiencing is with the output of my Media RSS, which is essentially a new standard allowing multiple media artifacts (like a video and a song) to exist in one item.

The Media element looks like this: <media:content> </media:content>

The output from this RSS Tool Kit looks like this: <content> </content>

otherwise everything works perfectly! I was able to generate a class, load it up with values, but when I emit the XML I don’t get a <media:content /> I get rather a <content /> which just won't work.

Does anyone know if there is a version that will support output RSS in the full Media RSS standard? Anyone know anything about support for Media RSS in this RSS ToolKit?

I'm attaching a text file with; My RSS template, my ASHX code, and my flawed output. Thanks for any help!

Best Regards,
bsteinwand

Commented Issue: Cannot read author/name field in Atom rss [25942]

jsmcmullen — Tue, 02 Mar 2010 06:13:05 GMT

Hi! It looks like control have a bug. I have tried to use your control to read rss http://ainstainergroup.blogspot.com/feeds/posts/default and I couldn't read the author field. I don't really into XSLT that's why I can't solve this problem by myself. Someone, help! How I can read author/name field?
Comments: ** Comment from web user: jsmcmullen **

For my blogspot blog, I found that if I add the following to AtomToRss20.xsl, you can then read the author name (but not the email).

Add the following to the list of xsl:element listings for the "items" template:

<xsl:element name="author">
<xsl:value-of select="child::*[name()='author']/child::*[name()='name']"/>
</xsl:element>

Commented Issue: RssHttpHandlerBase does not generate RSS/Atom feeds that are recognized by FireFox [20988]

PHeonix25 — Fri, 18 Sep 2009 00:41:59 GMT

I made changes to RssXmlHelper inorder to fix the generated RSS so that it would be properly identified by Firefox:

public static string ToRssXml<T>(T rssDocument) where T : RssDocumentBase
{
if (rssDocument == null)
{
throw new ArgumentNullException("rssDocument");
}

MemoryStream output = new MemoryStream();
XmlSerializer serializer = new XmlSerializer(typeof(T));
XmlWriterSettings settings = new XmlWriterSettings() { Encoding = new UTF8Encoding() };
XmlWriter writer = XmlWriter.Create(output, settings);
serializer.Serialize(writer, rssDocument);
output.Flush();
output.Seek(0, SeekOrigin.Begin);
StreamReader reader = new StreamReader(output);
return reader.ReadToEnd();
}

the problem is that by default XmlWriter generates UTF-16 and Firefox only identifies it when it is generated with UTF-8.

Also to get Atom to work I had to do 2 things:

Modify RssXmlHelper.cs (Line 351):

public static string DoXslTransform(string inputXml, Stream xslResource)
{
MemoryStream output = new MemoryStream();
XmlWriterSettings settings = new XmlWriterSettings() { Encoding = new UTF8Encoding() };
XmlWriter outputWriter = XmlWriter.Create(output, settings);

///TODO Make the culture an argument
using (StringReader stringReader = new StringReader(inputXml))
{
XPathDocument xpathDoc = new XPathDocument(stringReader);
XslCompiledTransform transform = new XslCompiledTransform();
using (XmlTextReader styleSheetReader = new XmlTextReader(xslResource))
{
transform.Load(styleSheetReader);
transform.Transform(xpathDoc, null, outputWriter);
}
}

output.Flush();
output.Seek(0, SeekOrigin.Begin);
StreamReader reader = new StreamReader(output);
return reader.ReadToEnd();
}

modify Rss20ToAtom.xsl:

Line 2: <xsl:stylesheet version="1.1" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.w3.org/2005/Atom">

I added the xmlns.

There may be more changes required, but these are the ones I have run across so far.
Comments: ** Comment from web user: PHeonix25 **

The other, quicker and easier solution that I have come up with is to remove the encoding parameter from the final document.

i.e.:
HttpContext.Current.Response.Write(RSS.ToXml(DocumentType.Rss, ns).Replace("encoding=""utf-16""", String.Empty))

Commented Issue: Custom item Element not acessible [21593]

PHeonix25 — Fri, 18 Sep 2009 00:39:28 GMT

Some RSS Feeds have some custom item elements other than fixed one (Title,Description, etc.)...Is there any feature in this toolkit o access those properties.
Example: Ths RSS( http://media.csis.org/itunesu/csisvideo.xml) has xml items like <itunes:author>,<itunes:subtitle> which are not accessible by RSS toolkit.
item>
<title>February 1-15 Highlights</title>
<itunes:author>Center for Strategic and International Studies</itunes:author>
<itunes:subtitle></itunes:subtitle>
<itunes:summary>This highlights video covers four major events at CSIS: supporting democracy abroad with David Price and David Dreier, a press briefing on Secretary Clinton's trip to Asia, Afghanistan, and a discussion of the recent stimulus package.</itunes:summary>
<enclosure url="http://media.csis.org/highlights/090220_february_highlights.mov" length="13054005" type="video/quicktime" />

<itunes:explicit>no</itunes:explicit>
<category>Global Challenges</category>
</item>
Comments: ** Comment from web user: PHeonix25 **

You'll need to specifically import the itunes namespace from the initial RSS declaration in order to read/write the properties with custom namespaces.
This isn't supported at the moment in the Toolkit.
I have submitted a patch to change the output to support these namespaces (i.e.: you can write nodes like "itunes:duration" by adding the itunes namespacing) but someone else will have to complete the same type of task for reading them.
My solution for the output (which wouldn't take too much work to change for input) is here http://aspnetrsstoolkit.codeplex.com/WorkItem/View.aspx?WorkItemId=22252

First off, everything that's been done in this toolkit is exceptional! Thank you!!

I'm having trouble getting the following Flickr Atom feed to generate code properly. The standard RSS information is generated properly, but none of the feed-specific namespace types are. Any suggestions?

I'm using version 2.0.0.0 and haven't had a problem with other feeds.
