Search And Exclude Before Import?

Hi There,

We absolutely love this plugin and its available functions!

We have a large CSV file (over 9,000 products) which is used to update multiple websites only a daily basis and is stored on a central external FTP server.

The issue i am facing is we have some products in the CSV that are not sold on some of our channels so i am trying to exclude them in an import on any particular website, unfortunately these are not category based and we need to search the ‘title’ and/or the ‘description’ for multiple keywords which we do no want imported.

We have tried to accomplish this via:

/node[handle[1][not(contains(.,"Tester"))] or handle[1][not(contains(.,"unboxed"))] or handle[1][contains(.,"Gift Set")] or type[1][not(contains(.,"Mini"))]]

However i am not getting the results i am after. Can this be done via nodes or some other way?

Any assistance would be greatly appreciated.

Thanks!
Ricky
