Web Table extraction stopped working

Hi,

Did anyone face a situation where an operator suddenly stopped giving results, so much so that even the tutorial process stopped working. I am working on "Web Table Extraction" operator which suddenly started giving a blank page as result. Initially I thought perhaps the web page might have changed which was not the case. After trying with different web pages, I tried with the tutorial process given in the HELP, that didn't work either.

Please advise, what I may be doing wrong here.

 

Regards,

Rajat

    hello @sharmar6 - I just ran the tutorial process for Read HTML Table and it worked perfectly.  Can you please post your process in XML (see instructions on the right)?

    Is it due to version mismatch issue  ?

    oh that is distinctly possible.  I strongly recommend always running the most current version due to many incompatibility issues.

    But my question is that what happened so suddenly, it was working fine till yesterday and stopped working now.

    I have no idea.  Last update was Oct 19.  We can see if @ey has any thoughts on this...  :)

    Good to know you found the actual issue. Just out of curiousity, if you feel like sharing, can you tell us in general terms the usecase for which you use this extension? As this extension is an output of a public project, I'd appreciate to know how its being used by the broader community.

     

    Thanks and Best Regards,

    Edwin

    Hi,

    I use this opertaor to extract survey data (election survey) and further process this data following some business rules. This operator has really expedited the whole process. Thanks for developing it.

    Dear sharmar6,

     

    Thanks for your feedback and appreciation. I am glad to know the operator expedites your workflow, and hopefully improves productivity.

     

    Best Regards,

    Edwin
