Helium Scraper

Hello, I need the ability to change selectors on the fly for the data from db. Is any way for this?

For example, I've made selector that selects link with text "hello", I manually changed text "hello" to "see you later", and now it selects the link with text "see you later". I need the ability to make this changes on the fly for texts from database. Is it possible?

You could start by importing this premade from the wizard. Just right click Project Explorer -> Globals -> Import Premade and visit the premade page. Then you'll be asked for a global name (you can just keep the default), and a selector and gatherer. For the gatherer, just use Gather.Text and as a selector use a selector that selects all the links you'll need, regardless of the text, since later on you'll filter by text.

Then, whenever you need to select a link with the text "my text" you can just do this:
Or to use text from a database:
