AppleScript to run on ALL opened Pages document instead of Active one.

Question

Hello,
I have many AppleScript i'm running on the active Pages document... but If I would like to run the Script on ALL opened Pages document?
What would be the line to add/modified at the top?
Thanks in advance...
Example of a script running on the active Pages document.
set theTargetWords to {"www.network"}
tell application "Pages" to activate
tell application "System Events" to tell process "Pages"
  -- Open the "Find & Replace" window:
  keystroke "f" using command down
     repeat until exists window "Find & Replace"
     end repeat
     tell tab group 1 of window "Find & Replace"
  -- Adjust the settings:
  click radio button 2 -- Advanced
          if value of checkbox 2 is 1 then click checkbox 2 -- Don't match case
          if value of checkbox 3 is 1 then click checkbox 3 -- Whole words
          if value of checkbox 1 is 0 then click checkbox 1 -- Search previous text (loop)
  click pop up button 1 -- find in
  click menu item 1 of menu 1 of pop up button 1 -- Entire document
  click pop up button 2 -- replace style
  click menu item 1 of menu 1 of pop up button 2 -- Any
  -- Delete every target word:
          set value of text area 1 of scroll area 2 to ""
          repeat with thisWord in theTargetWords
               set value of text area 1 of scroll area 1 to thisWord -- the target word
               click button "Replace All"
          end repeat
     end tell
end tell

Try this:
tell application "Pages"
    activate
    tell application "System Events" to set theOpenWindows to windows of process "Pages" whose subrole is "AXStandardWindow"
    repeat with thisWindow in theOpenWindows
        tell application "System Events" to tell thisWindow to perform action "AXRaise"
        tell front document
            -- ENTER YOUR CODE HERE
        end tell
    end repeat
end tell
