This is not really a plugin, so I am sorry for posting it here. Anyway this was the closest forum I found.

I created a javascript library and web app based on jQuery for programmers and non programmers to be able to scrappe html data that is not exposed through RSS or webservices.  

My goal was to create an app to create the scrapping services that was as simple and visual as possible. Also that it could be used relying as least as possible on the server side. Therefore everything except for the html content returned, happens on the client-side. The html though is returned by Yahoo servers (YQL).

The app is free and I thank you for using it and I will be more that happy to hear your critique, suggestion or bug reporting if you wish to share. I am sorry for the existing bugs and problems you might find. This is still a beta so I am sure you will find some. I have to work on the documentation so if you have doubts please contact me .

Here is a quick demo:

and here is the link for the app

Thank you jQuery to make it easier for javascript coders. Here is my contribution in return for all I've learned from the community. :)

Thank you and cheers,

PS: for those who want to write javascript to render the data returned by a jcrawl service in a customized way, you just have to write your code within function jcrawlReady. 

For this to work you have to:

1) set the parameter "returnHtml" to false (this var is in the script generated by jcrawl app)

2) match the serviceId from the jcrawlReady function with the parameter "serviceId"  from the script generated by jcrawl app

ex:

< script type = 'text/javascript' id = 'script_service10' >

jCrawl({ serviceId: "service 10" ,.......});

function jcrawlReady(serviceId,jcrawldata){

      if (serviceId == "service 10"){

            for(var i = 0; i < jcrawldata.length; i++ )

                   $("body").append("<div>" + jcrawldata[i].text + "</div>");

             }

      }

}

</script>
