Getting player names from raid window

[dx2]

Hi,
trying to address player names from raid window, I looked in the ex2ui_mainhud_raid.xml file and what I found is this:

:21994ba7acb4e75c:Longestnameposs

Can someone explain what this means ? It does not look like a dynamic data that I can use.

What I need the names for: Wanna make a new window that shows a filtered list of players who have detrimental effects on them that need to be cured.

I am sure it canbe done as soon as I have a solution to the player name problem.

PS: Is there any official documentation that explains the whole stuff? How the ui system is working, how variables are interpreted, addressed, exported, imported, available functions, handlers, events, etc. This is my first project on the ui and I have no clue how things play together apart from that what I investigated by analyzing some files.
