1 or many sub-items of an item

Here is the script:
import com.screenscraper.common.*;
DataSet allAdmins = scrapeableFile.extractData( dataRecord.get("ADMINS"), "EXTRACT" );

// Open up the file to be appended to.
out = new FileWriter( "teste.txt", true );

//write them down
out.write( session.getVariable("allAdmins") + "\t" );
out.write( "\n" );
out.write( "\n" );

out.close();

Here is the extractor pattern for admins:

"EXTRACT" Extractor Pattern:
~@LANG@~

Now, some questions:

*Anything wrong in the way I coded?
*What should I expect to find in allAdmins? A matrix?
*Does this work only in the professional edition?

Thanks again,
Carlos.

Thanks for your help!

I think I understand the logic. However, I'm still not confident of what would be in the second_extractor_patttern. Can you do it in the above html code? That's the real one.

I really appreciate it!

Carlos.
