A hint: All variables you declare in lua are global (accessible by other addons and overwriting existing variables), unless you add a local up in front.
To minimize compatibilty issues and pollution of the global namespace (table _G):

If you create an addon with an UI (like your scrolllist in XML, using variable DungeonHistoryXML as a global container), but you already got a global table (DungeonHistory) you could simply add a sub-table DungeonHistory.XML= {} (adding all variables and UI related functions to that)
instead of defining another 2nd global DungeonHistoryXML.

To speed-up the reference and make it easy to access them in your code you can add a local reference like local DungeonHistoryXML = DungeonHistory.XML at the top, below defining DungeonHistory.XML = {}
This will make your code below (in the same lua file) work the same as of before, only using the local reference, pointing to the global table DungeonHistory.XML (instead of a 2nd global variable DungeonHistoryXML).
-> Only in your XML files you'd need to change DungeonHistoryXML to DungeonHistory.XML as the variable DungeonHistoryXML would be local now, and not global anymore.

It's no "Must do it like that" but a best practice.
