The regular expression input for bulkremover works if I type in:

 

   

 

    fme_.*

 

 

But if I try to add another expression using the regex or it fails to recognize the regex statement

 

   

 

     fme__.*|igds_.*

 

 

I tested this statement using the ruby testing aplication recommended in the help section, and it was able to recognize the statement

Hi,

 

 

it seems you have two underscores after "fme" in the second statement, is that on purpose?

Hi,

 

 

Indeed. The current BulkAttributeRemover seems not to support some complex regular expression. In this case, you can use two BulkAttributeRemover in series.

 

1st: fme_.*

 

2nd: igds_.*

Hi,

 

 

In the stringsearcher it works.

 

 

I tried it in the bulkatt.rem.

 

I confirm it does not accept "pipelines". Only single line expressions. Nothing helps, braces, brackets..to no avail.

 

 

Pretty limited it seems.

 

 

You wil have to use 2 Bulkremovers in sequence to remove 2 attributes in bulk using a regexp.

also the regexp works, it seems the bulkremover does nothing with the result.
