Hi @qqilihq,

I’d like to suggest adding the option to return missing respectively “Ignore exceptions” if the XPath of the Table Extractor node doesn’t find anything or in case it’s combined with a Find Elements Node.

Combined with a find node it still errors out

XPath for testing `//table[@class="iana-table"]`

Trying to introduce fallback like adding empty rows wasn’t sucessfull:

I used this one instead:
