Data records don't change each other, unless they are subdata in a 
larger record. FCPageText is the raw page text connected to the page, 
not the printed result of it.

To see the text with expanded text inserts, you need to insert them 
manually.

For example in your inner loop, replace the found title tag with the 
File Info title string:

if enigmaString:IsEnigmaFileInfoTitle() then
      enigmaString.Luastring = titlestr.LuaString
end

After browsing the string for tags, you can transform your 
"enigmaStrings" string collection back to a full string with "resultstr 
= enigmaStrings:CreateString()".

Another approach would be to skip the splitting/parsing/etc and use the 
brute-force method of rawPageText:Replace("^title()", 
titlestr.LuaString). But that method would result in strange behaviour 
if the File Info text would ever contain the text "^title()".
