The String Builder Module allows you to build a string from multiple substrings – sometimes coded into the Yahoo Pipe, sometimes through user inputs. In this example, lets use the String Builder Module to search Twitter for info on concert/sports tickets. We’re going to build on our previous example from the URL Builder Module. Ready? [...]
URL Builder Module
The URL Builder Module in Yahoo Pipes allows you to manipulate and control how URLs are constructed. URLs are built from three main parts. http://finance.yahoo.com/rss/headline?s=tktm That URL returns news stories and stock quotes for Tickemaster. To get news and stock quotes for another company, we can simply change the “tktm” to another stock symbol. Lets [...]
Unique Module
The Unique Module will remove duplicate items. If your feed(s) has duplicate content, you can use the Unique Module in Yahoo Pipes to eliminate it and only show it once. http://api.search.yahoo.com/WebSearchService/rss/webSearch.xml?appid=yahoosearchwebrss&query=sliders+recipe+bacon+mayo&adult_ok=1 http://www.bing.com/search?q=sliders+recipe+bacon+mayo&go=&form=QBRE&filt=all&qs=n&format=rss In this example, lets look for recipes for “sliders”(mini hamburgers) that contain the ingredients: bacon and mayo. We can grab an RSS feed [...]
Union Module
The Union Module can merge up to five separate feeds into one feed. http://mlb.mlb.com/partnerxml/gen/news/rss/mlb.xml http://www.nfl.com/rss/rsslanding?searchString=home http://www.nhl.com/rss/news.xml http://www.nba.com/rss/nba_rss.xml In this Yahoo Pipes example, lets take a look at the news feeds for the MLB, NFL, NHL and NBA and merge them all into one feed. If we want to simply merge all these feeds together without [...]
Truncate Module
The Truncate Module will return X items (where X is the number you specify) from the top of a feed. It limits the output to the first X items. http://mlb.mlb.com/partnerxml/gen/news/rss/mlb.xml Lets take our same MLB feed from the Tail Module example, and limit it to the first 5 results. All we have to do is [...]
Tail Module
With Yahoo Pipes, the Tail Module will truncate (cut off) a feed to the last X items (where X is the number you specify). It limits the number of items at the end of the feed. http://mlb.mlb.com/partnerxml/gen/news/rss/mlb.xml Lets take a look at this MLB news feed… …and use the Tail Module to remove the last [...]
Reverse Module
Sometimes RSS feeds are ordered by publication date, alphabetically, or by other criteria and you need to arrange them differently. With Yahoo Pipes, the Reverse Module simply reverses the order the feed is in. http://news.google.com/news?um=1&cf=all&ned=ca&hl=en&num=100&q=2010+olympics&cf=all&output=rss In this example, we’ll take a look at a Google feed of the latest news regarding the Vancouver 2010 Olympics. [...]
Rename Module
The Rename Module will rename elements of the input feed. Sometimes the input data may not be in RSS format (ie. elements aren’t named “title”, “description”, “link” etc.), and you need to rename them accordingly to convert it to an RSS feed. The Rename Module works similar to the RSS Item Builder Module, Item Builder [...]
Filter Module
The Filter Module is a very powerful module that lets you filter certain data in or out of your Yahoo Pipe. A filter module can contain multiple rules that you specify to block or permit items. First select whether you want to block or permit items. Then whether you want to match all, or any [...]
RSS Item Builder Module
The RSS Item Builder Module works similar to the “Item Builder” module and the “Create RSS” module. It allows you to turn a non-RSS data source into an RSS feed by renaming the attributes in Yahoo Pipes. To use it, enter a data source in a “Fetch Data” module, YQL module, or Fetch Page module.
