how to pull new element added to an array?

sdetweil

right… you hard coded it…

justjim1220

So, is what I am wanting to do even possible?

sdetweil

@justjim1220 sure… just have to figure out how to find the feeds entry from the newsItem entry… you MAY/PROBABLY have to add something to the newsItem entries (every one) when they are placed in the newsItem array…

i can’t look at any of the rss code til thursday sometime…

@sdetweil

Note that that data is not part of the item. What code moves the xml to the Json object you are accessing?

sdetweil

looking at the code on my phone, the fetcher.js needs another method to parse out the source icon.

parser.on("image", function(image){})

To set a variable with the icon url,
That u can use in the

parser.on("item", function(item)

To add the icon url to each item to be able to use it during the display process

But not all RSS would have that channel.image. that is optional.

SO, I changed this part of the fetcher, but, after reading your posts, I am not sure if this is what you are talking about…

parser.on("item", function(item) {

			var title = item.title;
			var image = item.image || item.logo || item.img || item.svg || "";
			var description = item.description || item.summary || item.content || "";
			var pubdate = item.pubdate || item.published || item.updated || item["dc:date"];
			var url = item.url || item.link || "";

			if (title && pubdate) {

				var regex = /(<([^>]+)>)/ig;
				description = description.toString().replace(regex, "");

				items.push({
					title: title,
					image: image,
					description: description,
					pubdate: pubdate,
					url: url,
				});

			} else if (logFeedWarnings) {
				console.log("Can't parse feed item:");
				console.log(item);
				console.log("Title: " + title);
				console.log("Image: " + image);
				console.log("Description: " + description);
				console.log("Pubdate: " + pubdate);
			}
		});

It is looking like you are telling me I need to add a new section to the fetcher similar to this, but starting with

parser.on("image", function(image){})
			var title = image.title;
			var image = image.image || image.logo || image.img || image.svg || "";
			var url = image.url || image.link || "";

and would I also need this part?

                        if (image&& url) {

				var regex = /(<([^>]+)>)/ig;
				description = description.toString().replace(regex, "");

				images.push({
					title: title,
					image: image,
					url: url,
				});

			} else if (logFeedWarnings) {
				console.log("Can't parse feed item:");
				console.log(item);
				console.log("Title: " + title);
				console.log("Image: " + image);
				console.log("Description: " + description);
				console.log("Pubdate: " + pubdate);
			}
		});

And, would this be the way to add the image url in the config…

                        {

                                title: "New York Times",
				url: "http://www.nytimes.com/services/xml/rss/nyt/HomePage.xml"
                        },
			{
                                imageUrl: "http://online.wsj.com/img/wsj_sm_logo.gif",
				title: "Wall St. Journal",
				url: "http://www.wsj.com/xml/rss/3_7085.xml"
			},

Sorry, for all the questions, just really trying to learn all this…
AND, thanks for all your help!!! :smiling_face_with_sunglasses:

ok, then to use the definition in the feed entry
modify the node helper

			fetcher = new Fetcher(url, reloadInterval, encoding, config.logFeedWarnings);

			fetcher.onReceive(function(fetcher) {
                                // add code here to run thru the array of feed response items and add the icon url to each entry..
                                // the feed definition was passed in as parm to the containing method..   because this is a callback, you will probably have to bind the feed definition to this function
                                for( var item in fetcher.items())
                                {
                                     item.icon=this.feed_def.icon;
                                 }
				self.broadcastFeeds();
			}.bind({feed_def:feed}))

@sdetweil

well, sort of lost me there, but also getting a headache.

Gotta run some errands, I’ll look at it some more after a while.

AGAIN, THANK YOU for all the help!!!
