Getting access the Group elements in a stringlist


I asked this same question a few years ago and Achim gave me the answer. Unfortunately, the old forum looks to be permanently offline so I can't look up the answer.

I've got an XML parser that has an "XML Group Element" set to element name = "FILE", ID attribute = "name"

I'd like to programmatically get the value of this grouping element for the current string/string list.

Can you please show me a code snippet that allows me to access this information?
Best Regards
