I'm trying to hide a string starting with text 'Ref:". I know various ways of targeting specific text but this one is followed by a 6 digit random number. I can't figure out how to include the number since it is ever changing.

Although it can be in a different order, this is how it usually appears in the markup:

1. <small>(Delivery Options: Standard Shipping - $11.95, Delivery Date: 01/31/2014, Ref: 404927)</small>

How would I hide "Ref: randomnumber"...?

Thanks so much!

Susan
