Someone asked on Twitter how to refresh Safari window until a text is found. I thought that must be simple. Well, it still took me about an hour to put this together.

Reload until text found.applescript

tell application "Safari"
	activate
	try
		set urlForPolling to URL of front document
		set tabForPolling to current tab of front window
	on error
		display dialog "Please open some web page first" with title "Error" with icon stop buttons {"OK"} default button 1
		return
	end try
	display dialog "Reload the active page until a text is found." & return & "Enter the text to look for" with title "Safari reloader" default answer ""
	set needle to text returned of the result
	repeat
		set haystack to text of tabForPolling
		if haystack contains needle then
			say "Text was found on the page"
			exit repeat
		end if
		delay 3
		set URL of tabForPolling to urlForPolling
	end repeat
end tell
