Re: Export to XML?

You can do this using Action.ExportXML . Note that to run actions, the extraction logic must also be wrapped inside an action (since you can put sequences in actions, but not the other way around). So supposing Main is the global that performs the actual extraction, you can create another global wit...

Re: How to use regular regular expression in Helium 3?

Since version 3.1.2.8 we added text transformations, which support regular expressions. They can be accessed at Data Flow -> Text under Project Explorer.

See the Text item of the Data Flow documentation for more details, or let me know if you have any question about how this feature works.

Re: Clear database

I wouldn't recommend using the auto-generated ID as an identifier for data that has been extracted on separate extractions because if any elements are added or removed from the site, IDs won't match anymore. Instead, I would use the text or link of the element if you know they're unique within the s...

Re: Clear database

You can use Action.ClearData to do this. But note that you cannot mix actions and sequences (the ones you use to extract data and interact with the browser), so this needs to go into a separate Global. Suppose your global is called Main, which would also be the name of the output table(s). If so, ju...

Re: Infinite Scroll with a "Load More" Button

I will soon upload an infinite scroll tutorial. I think you're referring to the tutorials playlist. We've recently added a samples and fundamentals playlists. The fundamentals playlist is one I'd really recommend watching in full to get a clearer idea of how the whole extraction process works in Hel...

Re: Clear database

You can right-click the Database icon and select Clear Database. Note that this will clear the whole database. Or you can right-click a particular table set inside the database and select Clear All Data.

Re: Not extracting data when Browser count over 1

I think the auto-parallel may be messing something up. Would you mind sharing your project (you can send it to our support email if you prefer)? Also, you could try setting Auto Parallel to False on Project -> Settings . If you do so, you'll need to use Sequence.Parallel explicitly if you'd like to ...
