RSS feed on dashboard

[karcio]

Hi guys,

I'm new with node-red, I want to display RSS feeds on dashboard, but so far I can only display last feed not all, I was trying use template and text. No luck so far, should I use loop?

[{"id":"1a287e46.6039fa","type":"ui_template","z":"e8db5bfc.e69288","group":"8c8d1686.82337","name":"","order":1,"width":0,"height":0,"format":"<div ng-bind-html=\"msg.payload\"></div>","storeOutMessages":true,"fwdInMessages":true,"templateScope":"local","x":966.6666870117188,"y":195.83334350585938,"wires":[[]]},{"id":"8c8d1686.82337","type":"ui_group","z":"","name":"RSS","tab":"43b3d1f8.d20da8","disp":true,"width":"6","collapse":false},{"id":"43b3d1f8.d20da8","type":"ui_tab","z":"","name":"Home","icon":"dashboard","disabled":false,"hidden":false}]

Unfortunately your flow isn't currently importable.Please read the following post How to share code or flow json and then edit the above message.

Take a look at this example of how to build a table.

EXAMPLE (template) - displaying a two dimensional table

Problem: You need to display a table with first name, last name and age. Sample data: Paul Doe, 24 Greg Jones, 31 Able Smith, 29 We will use a function node to create the table like this: [55%20AM] And display the table using the template node. Here is what we use in the template node: [09%20AM] In this case we use the ng-repeat twice, once to process each row of the table in the <tr> and once to display each item in each row using a <td> element. Here is what the display will look li…

You will also need to add a debug node to your RSS feed to see how the data coming out is formatted

I think I'm doing something wrong, bacuse now with

<table id="table" >
 <tr>
    <th>content</th> 
  </tr>
 <tbody>
 <tr ng-repeat="row in msg.payload">
    <td ng-repeat="item in row" >{{item}}</td>
 </tr>
 </tbody>
</table>

Nothing displayed, only content but not articles. My feed format is just string like
"string"

Without seeing what the input is, there is no way to know what is going on.

[karcio]

OK, this is my input

You are sending an object not an array which the example uses

[ukmoose]

That also only shows one article so that's all there is to display

[karcio]

@zenofmud

You are sending an object not an array which the example uses

How can I turn this to json array?

[zenofmud]

You will have to convert it somehow maybe with a function node. You will only get one row in the output as it stands now.

[ukmoose]

Lets take a step back...

@karcio

I want to display RSS feeds on dashboard, but so far I can only display last feed

The debug output you posted only has one post, so assuming you still want to display more than one post, you need to fix that problem first. How are you getting the RSS feed into Node-RED?

[karcio]

@zenofmud

You will have to convert it somehow maybe with a function node. You will only get one row in the output as it stands now.

Using feedparser

[ukmoose]

the feedpasser node only passes on new entries (as described in its readme)

So you could get zero, 1 or many results.

If you want the last 5 entries you would be better off using the http request node.

[karcio]

thank you, Ok, so I did try http request

and now my payload looks like:

<?xml version="1.0" encoding="UTF-8"?><?xml-stylesheet title="XSL_formatting" type="text/xsl" href="/shared/bsp/xsl/rss/nolsol.xsl"?><rss xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:content="http://purl.org/rss/1.0/modules/content/" xmlns:atom="http://www.w3.org/2005/Atom" version="2.0" xmlns:media="http://search.yahoo.com/mrss/"> <channel> <title><![CDATA[BBC News - World]]></title> <description><![CDATA[BBC News - World]]></description> <link>https://www.bbc.co.uk/news/</link> <image> <url>https://news.bbcimg.co.uk/nol/shared/img/bbc_news_120x60.gif</url> <title>BBC News - World</title> <link>https://www.bbc.co.uk/news/</link> </image> <generator>RSS for Node</generator> <lastBuildDate>Wed, 26 Jun 2019 15:03:53 GMT</lastBuildDate> <copyright><![CDATA[Copyright: (C) British Broadcasting Corporation, see http://news.bbc.co.uk/2/hi/help/rss/4498287.stm for terms and conditions...

And I can display all on page like

Could you please tell me how can I format xml? Should I use xml node for that?

[ukmoose]

well you could try…

Although I thought this was to be in the dashboard so I don’t understand you starting with a http-in node

[bakman2]

you need to convert it to json first.
