I've got this customer who asked if it is possible to create an rss feed for the 2sxc news app.
I'm wondering if this is possible in some way, or if anyone has set something like this up...
I can kind of set up an api, which will return xml like output, but it still says:
Feeds should not be served with the "application/json" media type
Just found out .... add
using System.Net.Http
and then create a standard httpresponse with returntypes etc.
var res = Request.CreateResponse(HttpStatusCode.Ok);
res.Content = new StringContent(sb.ToString(), System.Text.Encoding.UTF8, "text/xml");
return res;
That's the spirit :). BTW: In 2sxc 12 we're adding new helpers to stream file results. YOu should then be able to just create an api and return File(contents: xmlObject). Almost done...

I am trying display the content from taxonomy by using Ektron CMS with ASP .Net
By using the taxonomy path i got the id and trying to display the content.
But i am getting content as null.
Please let me know the possible solutions to solve this.
Waiting for experts answers.
Thanks,
In my development environment, I have the following taxonomy:
const string eventsTaxonomyPath = "\\Upcoming Events";
const long eventsTaxonomyId = 89;
It sounds like you already found this method (or something like it) in what I like to call the "Legacy API":
var taxonomyApi = new Ektron.Cms.API.Content.Taxonomy();
var taxonomyId = taxonomyApi.GetTaxonomyIdByPath(eventsTaxonomyPath);
Without any info on what version you're on, I'll assume it's a recent (8.5+) version. The Framework API makes it really easy to get the content from a given taxonomy. Below are a couple of ways that work on v9.0 and will most likely work in anything 8.5+ -- in the developer briefing webcast the only major change for the Framework API in v9 was the inclusion of the e-commerce namespace.
Getting the full taxonomy tree via the TaxonomyManager:
var taxonomyItemManager = new Ektron.Cms.Framework.Organization.TaxonomyManager();
var taxData = taxonomyItemManager.GetTree(eventsTaxonomyId, includeItems: true);
Getting all the content recursively from a given taxonomy folder via the ContentManager:
var contentManager = new Ektron.Cms.Framework.Content.ContentManager();
var criteria = new ContentTaxonomyCriteria();
criteria.AddFilter(eventsTaxonomyPath, true);
criteria.ReturnMetadata = true;
var content = contentManager.GetList(criteria);
The potential downside to the ContentManager way is that you lose the hierarchical taxonomy structure. The upside to using the ContentManager is that you can tell it to include all the metadata for each content block. That's not possible with the TaxonomyManager or TaxonomyItemManager.
My guess is that the "Get Content By Taxonomy" function you are using by default does not fetch the content. You can either-
a) Use the ID to get the content via the content manager API
b) Investigate if the function you are using has an override to include content.
I would like to get and display the itemxml of the selected item from the Tridion CME.
I was able to get the Itemxml from my VM server when i give the tcm id in the browser.
However, i would like to get the same information from Tridion GUI Extension.
I am able to get the selected item tcm id. Is there any way to get the itemxml using coreservice?
or is there any other way to get this?
At the moment there's no way you can get Item XML through core service. Item XML you have seen was provided to you by TCM Protocol handler that might not be there in future versions. If you want to show item XML in CME - take a look at this extention by Yoaw:
http://sdltridionworld.com/articles/sdltridion2011/tutorials/GUIextensionIn8steps.aspx
Also, keep in mind that not all properties of an item might be exposed in Xml, sometimes you have more info in Data object
Take a look at the PowerTools, it has an ItemXML viewer (written by Robert Curlette) for all items in SDL Tridion
http://code.google.com/p/tridion-2011-power-tools/wiki/ItemXML
The XML is loaded on a tab using JavaScript as follows:
ItemXmlTab.ItemXmlTab.prototype.updateView = function ItemXmlTab$updateView()
{
if (this.isSelected())
{
var xslPath = $ptUtils.expandPath("/PowerTools/Client/ItemXml/ItemXmlTab.xslt", true);
$xml.loadXsltProcessor(xslPath, function (value)
{
var xmlSource = $display.getItem().getXml();
// Filter out all spacing characters
xmlSource = xmlSource.replace(/\t|\n|\r/g, "");
var html = $xml.xsltTransform(value, $xml.getNewXmlDocument(xmlSource), null);
$dom.setOuterHTML($("#itemXml"), html);
});
}
};
You can view the source code of the extension at http://code.google.com/p/tridion-2011-power-tools/source/browse/#svn%2Ftrunk%2FPowerTools.Editor%2FPowerTools%2FClient%2FItemXml%253Fstate%253Dclosed
You can get the item XML via CoreService, but this will get you the Tridion R6 (2011) Xml format, which is not the same you would see before.
Sample code available here.
I tend to have a page "GetItemXml.aspx" on my Tcm servers that I then call with a Uri as a parameter, and then this page would return the Item Xml.
Article written by Yoav Niran (Url in the post of user978511) is perfect for your requirement.
if you are still facing any issue and in hurry to get it working just perform below steps -
1- Download the extension.
2- Apply the steps 7 and 8 of this article to configure this extension.
In View,
#{
Layout = "~/Views/Shared/site.cshtml";
ViewBag.Title = "Organizations";
var organizations = "";
foreach (var org in Model)
{
organizations += "'" + org.Name + "':'" + org.Id + "',";
}
organizations = organizations.Substring(0, organizations.Length - 1);
}
Result operation: organizations = "'Passport':'14f0eac0-43eb-4c5f-b9fe-a09d2848db80','Bank':'ad1d77d8-7eb1-4a4c-9173-b0f2f7269644'";
Output the data in section JS code.
But when viewing the source code of the page in the browser, not getting what wanted.
What's the problem? How to make a normal quotes?
JS: "data": "#organizations"
Result in view webpage returned "data": "'Passport':'14f0eac0-43eb-4c5f-b9fe-a09d2848db80','Bank':'ad1d77d8-7eb1-4a4c-9173-b0f2f7269644'"
OK cool Q,try this source:
#{
var model = Model.ToArray().Select(org => string.Format("'{0}':'{1}'", org.Name, org.Id));
var data = string.Join(",", model);
}
#Html.Raw(data)
What if you change
"data": "#organizations"
to
"data": "#Html.Raw(organizations)"
#Html.Raw(content)
And check this one out: http://jeffreypalermo.com/blog/what-is-the-difference-in-lt-variable-gt-and-lt-variable-gt-in-asp-net-mvc/
In your code example here, the culprit is the
#organizations
that generates the quotes. You could instead use:
#Html.Raw(organizations)
Okay, that's great, but by creating JSON, you are doing work the framework could be doing for you. You probably want a model that the framework can serialize for you. This way you don't even need any code in your view header at all.
#Html.Raw(JsonConvert.SerializeObject(Model.ToDictionary(m => m.Name, m => m.Id))))
Above, note that I'm using Json.NET, which you probably want to NuGET into your project because Microsoft is moving to it. No point in figuring out how to use the old JSON serializer to do this. Also note that unless you are using the model for other purposes, you might choose to do the dictionary conversion outside the view, reducing the code-work in the view.
Next, if you are embedding JSON in the view, you might want to consider one of two other options. If the amount of data will be small, consider using the join method proposed by eli (here), but instead encoding it in HTML 5 "data-" elements and loading it using JavaScript. That way you keep javascript out of your view. It's just one more step of confusing when debugging javascript, looking for variables that are initialized by dynamically-generated HTML.
Better yet, create a reusable HTML helper method to transform your model into data attributes: How to use dashes in HTML-5 data-* attributes in ASP.NET MVC
Finally, if there are MANY JSON elements, consider sending the data separately. Render it with a simple Json() method in your controller, and get it with a simple jQuery $.json() in your client-side code. See here for an example
Good luck!
I’m very new to programming with RSS feeds to please forgive me if this sounds like a really general question.
Is it possible to take multiple RSS feeds from multiple sites and combine them as a single object to show to the end user?
For example, could I take the latest news headlines from one site, the latest blog updates from a totally different site and combine them into a single list to show the user?
I have seen this sort of question asked before and it seems like its possible, but the slight twist is I want to let the user add any feed that they want from any source
I’m looking to do this in ASP.NET
Many thanks!
You can use the SyndicationFeed class to work with RSS feeds in .Net.
You probably want to do something like this (untested):
var allItems = new List<SyndicationItem>();
foreach(var feedUrl in whatever) { //In your list of urls
using(var reader = XmlReader.Create(url))
allItems.AddRange(SyndicationFeed.Load(reader).Items);
}
var newFeed = new SyndicationFeed(items);
//Do something with newFeed
You should add error handling in case one of the feeds is unavailable or invalid.
It is possible, yes.
For a good example of this kind of thing in action, check out Yahoo! Pipes.
This would probably be a good application of LINQ to XML, but I'll leave the implementation up to you.
How do I create an rss feed in ASP.Net? Is there anything built in to support it? If not, what third-party tools are available?
I'm thinking webforms, not MVC, though I suppose since this isn't a traditional page the difference may be minimal.
The .NET Framework 3.5 has added a SyndicationFeed Class which allows you to create and/or consume feeds in Atom 1.0 and RSS 2.0 formats.
SyndicationFeeds Class on MSDN
For built-in, there's nothing stopping you from using XmlDocument or XDocument (3.5) to build up the required XML for RSS. It's more work than it's worth though.
I use the Argotic Syndication Framework and serve the feeds through Generic Handlers (.ashx) with the content type set to text/xml.
The RSSToolkit is also nice. It comes with an RSSDataSource control if you're into that sort of thing. It also includes a control that will automatically insert the meta tag required for feed autodiscovery in browsers. I found the build provider for creating feeds to be a little kludgey however.
Here's an RSS framework created by a Microsoft developer: ASP.NET RSS Toolkit
Use one of the libraries available for generating the actual RSS. For example: http://www.rssdotnet.com/
If you check the code examples page at the bottom:
http://www.rssdotnet.com/documents/code_examples.html
you will find the code for clearing the content type in an ASP.net Page and outputting the RSS.
Something along the lines of (not tested, not compiled, just typed):
public void PageLoad()
{
// create channel
RssChannel _soChannel = new RssChannel();
// create item
RssItem _soItem = new RssItem();
_soItem.Title = "Answer";
_soItem.Description = "Example";
_soItem.PubDate = DateTime.Now.ToUniversalTime();
// add to channel
_soChannel.Items.Add(_soItem.);
// set channel props
_soChannel.Title = "Stack Overflow";
_soChannel.Description = "Great site.. jada jada jada";
_soChannel.LastBuildDate = DateTime.Now.ToUniversalTime();
// change type and send to output
RssFeed _f = new RssFeed();
_f.Channels.Add(channel);
Response.ContentType = "text/xml";
_f.Write(Response.OutputStream);
Response.End();
}
Hope that helps.
You could take a look at Argotic. It is a really cool framework.
