extracting from a string - Classic ASP

Hi there,

My string ("texto") is always something like that:  texto = 427_7/13/2017

I mean: three digits (none zero), the "_" symbol and a date (of course as a string).

How could I extract from "texto" only the date, that is, the "7/13/2017" in this example, so that I can store this date in a certain field in a table of a database?  

Important: please take into account that the "texto" date might be (for example) texto = 427_12/13/2017 and, in this case, of course I want the extraction to be the full date, I mean, exactly 12/13/2017 .

Thanks!
