Re: Scroll part of the screen

The InfiniteScroll action should work even if the scrollable area is not the whole page, but I see that you have one scroll loop after another. That would only make sense if you have one scrollable area inside another one, which I don't think is the case on this site. Can you send screenshots or the...

Re: XML Formatting

You can do this by renaming your tags column on the top extract to tag , and renaming your tag column on the nested extract to value , so that it looks like this: […] extract [name] [value] tag extract value [value] Whenever an extract has a single column called value, Helium will ignore this column...

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...
