Add You - Consuming RSS Feeds With ColdFusion
Everyone makes fun of the Cable Man and the lousy service for repairs or installation and yet the Cable Company takes all that negative perception and simply deals with it. Yet it is a wonder more cable companies do not get more involved in community driven public relations campaigns. By what types of things can a cable company do? Give out free signals to churches, Boys and Girls Clubs or day care centers? Heck they are probably stealing the signal already?May I put a suggesting in for Cable Company participation in a mobile neighborhood business watch program? Why you ask, well consider how many vehicles they already have out on routes all day already and lets take a look at the over all business model for a second shall we?
As you can see displaying an RSS feed in ColdFusion is easy and provides real time up to date information that you can provide to your visitors on your website.
You can apply style sheets and html formatting to your feeds and present the information in a pleasant looking way that visitors will enjoy reading.
An example where I use these feeds can be seen in action here http://www.news-junkie.net. This is a personal site that I had developed a while ago that is a simple news aggregation website with a number of different topics. I found it fun to develop and good practice working with xml and ColdFusion. The information is constantly updated and visitors to my site see fresh new articles ev
Today, we’ll cover another set of benefits to selling Big Ticket items. BUT… this time we’ll specifically focus on the benefits of selling Big Ticket items as an AFFILIATE. First, we had better define both Big Ticket Item and Affiliate. A Big Ticket Item is any product or service that sells for more than $500 or $1000. An Affiliate is someone who sells other people’s products. Or, at least, those are my definitions. I’m sure there are other possible definitions but for this article, let’s stick with the simple descriptions I’ve given, ok? Now, let’s take a close look at the BIG Benefits to selling Big Ticket Items As An Affiliate. Benefit #
Web services, RSS, XML, SOAP to name several, are all welcomed friends to the ColdFusion web development language. This article will focus on the likes of RSS and XML.
Definition:
RSS is a family of web feed formats used to publish frequently updated digital content, such as blogs, news feeds or podcasts. Consumers of RSS content use special browsers called aggregators to watch for new content in dozens or even hundreds of web feeds. The initials "RSS" are variously used to refer to the following standards:
Really Simple Syndication (RSS 2.0)
Rich Site Summary (RSS 0.91, RSS 1.0)
RDF Site Summary (RSS 0.9 and 1.0)
RSS formats are specified in XML (a generic specification for data formats). RSS delivers its information as an XML file called an "RSS feed", "webfeed", "RSS stream", or "RSS channel".
That's the Wikipedia definition for an RSS feed. What's not mentioned is that developers are able to take advantage of the content provided by these RSS feeds to display current and changing data on their websites, which adds value to the website and hopefully bring return visitors for more of the information that you provide.
Consuming an RSS feed in ColdFusion can be as simple or as complicated as you want it to be. There are several ways or more, to do this in ColdFusion. Parsing through array elements and defining the parent elements to children and testing for grandchildren elements, and recursive behaviors etc. But this article is not for the experienced ColdFusion developer. This article is for someone who might like to see some of the "ease of operation" of ColdFusion and how it relates to a popular web practice known as RSS.
We'll look at a fun and popular feed from RollingStone Magazine. Located here http://www.rollingstone.com/rssxml/album_reviews.xml as of the time of this article.
It's a feed that I have implemented on several of my websites. Now it's important to note that you should select feeds that are relevant to your website, I have several music based websites and thus having an "Album Review" feed was appropriate. Ok, so now what do we do with this feed you ask? Well, basically there are only 3 steps to consuming and parsing an XML/RSS feed.
1. Read the Feed in
2. Loop through the elements of the feed
3. Display the feed
Am I simplifying things a bit? Not really, the purpose here is to show how ColdFusion can do much of the 'heavy lifting' as it pertains to application development making many day to day programming tasks much less tedious.
Here's an example:
In ColdFusion we read the feed in like this.
< cfhttp url="http://www.rollingstone.com/rssxml/album_reviews.xml"
method="GET" resolveurl="No">< /cfhttp >
< cfset album_reviews_xml=XMLParse(cfhttp.FileContent) >
What this does is utilize the CFHTTP tag in ColdFusion which has many many uses, in this case it performs the request for the XML document on the server.
The second line defines a variable called "album_reviews_xml" and gives it the value of the http response. Using the built in function "XMLParse()" in ColdFusion takes the http response and delivers it to your browser in XML format or as an XML Object for you OOP guys.
If you would like to have ColdFusion show you a 'pretty' presentation of the XML you can simply add a cfdump statement to your document and you will see a nicely rendered and easy to read xml structure.
The next step is parsing or looping through the elements of the XML Object.
You do that like this:
< cfoutput >
< cfloop index="x" from="1" to="#ArrayLen(album_reviews_xml.rss.channel.item)#" >
Title: #album_reviews_xml.rss.channel.item[x].title.xmlText#
Link: < a href="#album_reviews_xml.rss.channel.item
[x].link.xmlText#" >click here< /a >
Description:#album_reviews_xml.rss.channel.item[x].description.xmlText#
< /cfloop >
< /cfoutput >
This loop as shown, iterates through all of the elements of the document and displays the most common items in an RSS feed which are the TITLE, LINK and DESCRIPTION. Some feeds aren't formed entirely to standard and may have other elements designs, and of course this is not all of the data that you can get from an RSS feed, again it's just the most common and standard elements returned through RSS. But if the document provided by the RSS feed generator is to standard and well formed, you will see these 3 elements in most every RSS feed.
As you can see displaying an RSS feed in ColdFusion is easy and provides real time up to date information that you can provide to your visitors on your website.
You can apply style sheets and html formatting to your feeds and present the information in a pleasant looking way that visitors will enjoy reading.

Pay-Per-Click or PPC is the fastest growing out of all segments of advertising including traditional as well as online media. With that in mind it is absolutely essential that you understand exactly which PPC advertising platform is best suited for your unique business needs or you may be left in the virtual dust. Throughout this article I will compare and contrast the three giants Google AdWords, Yahoo! Search Marketing and the freshly launched Microsoft adCenter in order to shed some light on the unique aspects and features of each platform. I will cover three main areas of each platform consisting of ad distribution, demographics and tools. When you have completed reading this article you will possess the knowledge required in order t

Statistics show that most people would like to own their own business and be their own boss. Most people also think it takes a lot of money to start a business. This is not necessarily true.There are many service businesses that can be started with little or no money. We all have a talent or knack for something we enjoy doing. So why should we not be doing what we enjoy and make money at the same time?I am going to list some ideas of interests and talents you can make into a business:1. Baby sitting: Requires a nominal fee to be licensed (if required in your state) and an extremely organized person with lots of patience and compassion for children.2. Personal Shopper: For those of you that are shopaholics, this i

The sun seems to be setting on the world of reciprocal link exchange. Sites that major on that may have to switch to a new paradigm, or go down like the titanic.The major search engines seem to frown at reciprocal link exchanges, and gradually it is becoming obvious that chasing reciprocal links for the purpose of enhancing search engine rankings is becoming a dying art.It was pretty contrived while it lasted. You set up a link page, and dump links there. Some webmasters did not bother to categorize the links. On the same page, you will find viagra, mortgage finance, debt consolidation, travel agency, Chinese porcelain, psychics and all the work. Visitors hardly visit such link farms.Reciprocal link exchanges, as practi

Years ago before the internet was born, starting your own business was like taking a leap into the unknown. It involved MONEY, TIME, and lots of worry. If you were one of the lucky ones your business was a success, but many were doomed to failure.Now the Internet has evolved, and though many businesses fail possibly through lack of understanding! no one loses a fortune.When someone begins the search for a business on which to make money, it is almost always an affiliate program that catches their eye, probably because most of them say Free To Join. Yes they are free to join, but if you are looking to work and make money it is almost certain that you will have to upgrade and pay a monthly fee.Understanding the pro
