The new HappyHarvester version 2
Migration notes

The new HappyHarvester version 2 has changed in many ways compared with previous versions 1.x. If you are a HappyHarvester 1.x user, please read these notes to learn of the most salient differences between v2.x and v1.x.

Version 2 is a vastly improved version of HappyHarvester 1. It is a major upgrade where we have changed the way a harvest is done. Not only the interfaced has changed, the extraction engine itself has been set up in a new way. This brings new possibilities for data extraction that were previously impossible.
 
Rule based extraction engine
The previous version of HH 1.x let you work with a set of pre and post strings. HH simply harvested all strings on a page, from top to bottom, occuring between the pre and post strings. This worked fine in most cases, but bore limitations in cases where data was incomplete or less straightforward to harvest.
The new version 2 uses rules to extract data. A rule can not only do a harvest between a pre and post string, but can do many other things as well like extracting an image.

Rules in Normal Mode
There are two different rule engines, named "Normal mode" and "Advanced mode". The normal mode comes the closest to harvesting in the 1.x version. In HH 1.x you could for example do:
   pre string: <td>, post string: </td>
   prestring: <div>, post string: </div>
and it would harvest all text between <td> and </td>, then start on the top of the page, and then get you all text between <div> and </div>. In Normal mode in HH 2, you would use:
   Get Text between <td> and </td>. Find 1000 instances.
   Get Text between <div> and </div>. Find 1000 instances.  
and it would do exactly the same.

The Advanced Mode
Advanced mode offers you much more. Instead of starting the harvest anew from the top of the page when a rule has finished (like in Normal Mode), the engine will remember the page position. This offers you a hand hold to harvest structured data - pieces of data that belong together and need to stay together, like a product and a price, for example. Refer to the Help to find out more about Advanced mode.

You need a new serial for version 2.x
Version 2 is a major upgrade to which existing users of HH 1.x need a new serial. Your old 1.x serial will not work in version 2. As a registered 1.x user, you can upgrade at a reduced price.
