Helium Scraper

Sorry for the long wait. Please send a support request here, including the email you used to purchase Helium, and I'll look into this.

I'm assuming you have a table that you don't want to export if it's empty? Supposing you have a table called Test , you can first create a query by right-clicking your table ( Data.Test in this case) in Project Explorer , selecting Create Query , leaving everything with the default values and pressi...

You can do this using a single selector that selects all images. But note that the columns must be already defined (they cannot be created dynamically at run-time). Since each column will always extract the first item selected by the selector, you can use Sequence.Skip to skip images like this: extr...

I'll just copy/paste my response to the other similar question. Just right-click Text.Iframe_url and select Output Result (or alternatively, left-click it and press the space bar). A placeholder [name] at the bottom will appear: Text.Iframe_url as [name] Then replace the [name] placeholder with a va...

You're pretty close. Just right-click Text.Iframe_url and select Output Result (or alternatively, left-click it and press the space bar). A placeholder [name] at the bottom will appear: Text.Iframe_url as [name] Then replace the [name] placeholder with a variable name, such as url , and finally repl...

This function needs an actual query, not a query name as the first argument, so something like this would work: Action.ExportQuery · "select * from MyTable" · "hello.csv" · true If the query is large or has multiple lines, you can also use a script at Project Explorer > Scripting > Scripts since scr...

That's now easy to do (since version 3.2.7.9) with the WhileAny function. In the documentation there's an example showing how to stop the extraction when a post with a certain text is found. In your case, you could, first create a query at Project Explorer > Data Flow > Queries that gets the latest ...

Note that clicking a button 50 times and then extracting the content involves exact same steps as, in a site that has pages, clicking the next button to turn the pages 50 times, and then extracting from the 51st page. So you can use Browser.TurnPages to repeatedly click the button (or even better, B...

That's how it's meant to work, when there is no next button, it extracts the current page and then it stops. Are you not getting results from the last page?

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: Sequence.IfAny · Select.Header · [ifAny] · Sequence.Empty Then just replace [ifAny] with whatever actions extract from the p...
