Editing WoW:API GetFactionInfo (section)

== Example ==
 for factionIndex = 1, GetNumFactions() do
   name, description, standingId, bottomValue, topValue, earnedValue, atWarWith,
     canToggleAtWar, isHeader, isCollapsed, hasRep, isWatched, isChild = GetFactionInfo(factionIndex)
   if isHeader == nil then
      DEFAULT_CHAT_FRAME:AddMessage("Faction: " .. name .. " - " .. earnedValue)
   end
 end

====Result====
:Prints each faction's name and earned value.
 Faction: Cenarion Circle - 2785
 Faction: Argent Dawn - 405
 Faction: Thunder Bluff - 15042

=== looping over all factions ===
The above code will only loop over those factions visible in the faction panel and thus not include those in collapsed headers.
To loop over all factions, including the hidden ones, you can use the following code.

 local factionIndex = 1
 local lastFactionName
 repeat
   local name, description, standingId, bottomValue, topValue, earnedValue, atWarWith,
     canToggleAtWar, isHeader, isCollapsed, hasRep, isWatched, isChild = GetFactionInfo(factionIndex)
   if name == lastFactionName then break end
   lastFactionName  = name
   -- YOUR CODE HERE --
   factionIndex = factionIndex + 1
 until factionIndex > 200
