Example 2 – Making Yahoo Pipes work for you

Filed under: cool stuff, tech — seniorgeek @ 11:38 am

Ok, I said I would have example 2 in a couple of days. So follow along with example 2.

Since I am always looking for the best tech deal, I created the following pipe. It checks 8 sites for the best price on the item you select. Open the following pipe in the edit mode and follow along.

This first thing we need is the ‘text input’ module so we can select what we are looking for.


Next we need to know what sites we are going to seach. For this we use the ‘fetch’ module to input the URL of each site.


You can select as many sites as you want but I have found out that is you put more than 6 sites in a ‘fetch’ module it really slows down the search. Use multiple ‘fetch’ modules if you need more that 6 sites.

Next we need to filter out duplicate results from each site so we use the ‘filter’ module.


Now we link the output from the fetch module to the filter module to get rid of all the duplicates.
We also need to link the output of the ‘test input’ module to the filter module at the ‘text’ input of the description and title because this is the item name we are searching.

Now there is one special item I should mention here. I have created another pipe called ’embedded’ which I add to this pipe because it already has some predefined searches built. You can examine that pipe later if you want. I just wanted to mention it here.

Once we have the outputs of the the ‘filter’ and ’embedded search’ tied together with the ‘union’ module we can sort the output as we desire. I have sorted this by date in ascending order because I want to know what is the most recent tech deal out there.

The following is the complete pipe for your review. Feel free to post comments or ask questions.




  1. Sometimes the pubDate is hopeless for sorting because it doesn’t stick to a standard format. I got round this by looking at the y: values for day, month and year.

  2. I should have said: look at the rename and regex operations to see how I overcame the inconsistency. I could have probably done it more easily with udate.

  3. Cancel my remarks about pubDate and sorting. It was displaying the date correctly on output that I was trying to achieve.

    Sorry – a lot of water has gone under the bridge since then.

  4. David, thanks for your thoughts. I was surprised to see your comments as it always showed the correct date sequence when I ran the pipe.

  5. See note 3 above. It was the pubDate formatting that was bugging me. The sorting was fine.
