If this is an element on a page, such as a title, you first need to create a selector that selects this element (suppose you call it Header), and then use the following code:

Code: Select all

Sequence.IfAny
   ·  Select.Header
   ·  [ifAny]
   ·  Sequence.Empty

Then just replace [ifAny] with whatever actions extract from the page, such as an extract action:

Code: Select all

Sequence.IfAny
   ·  Select.Header
   ·  extract
         header
            Select.Header
         description
            Select.Description
         price
            Select.Price
   ·  Sequence.Empty
