Re: An error occurred install Helium Scraper 3 ??

Hi,

Try modifying the user to have admin rights. You should be able to change it back to normal user after installing it.

Alternatively, try manually downloading the Helium Scraper 3.application file and running it. This is a hacky solution so I'd recommend trying the admin rights first.

Re: Infinite scroll stop after a couple scrolls

The slow scroll premade won't help here since that scrolls just once. I've noticed that the site sometimes won't load more items after scrolling to the bottom, even when manually scrolling, so when this happens Helium will think there are no more items and stop scrolling. Note sure if there's much t...

Re: Activation code expired?

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.

Re: Only export to CSV if not empty?

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...

Re: Selectors: Extracting multiple rows of data into individual table columns

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...

Re: Extracting data from iframe on another domain

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...

Re: Iframe

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...

Re: Action.ExportQuery

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...

Re: While Loop Function in recurring actions

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 ...

Re: Sequencing Click to Load additional Elements, then, Extraction Logic

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...
