Safari do JavaScript window.getSelection() workaround & Filemaker

To document web pages using Safari + Applescript and Filemaker pro 8 Advanced

I am building some routines, including this one:

==== my test script
tell application “Safari”
set the_title to name of window 1 as string
set the_URL to URL of document 1 as string
end tell
set quote_text to “ " & the_title & " ” & return & “ " & the_URL & " ” & return & “ "
tell application “Safari” to set the clipboard to quote_text & (do JavaScript “window.getSelection()+‘’;” in document 1) & " ”
=== en my test script ===

The problem maker was some changes that made the javascript get Selection not react

I did found a workaround at

http://joemaller.com/2005/04/24/getselection-workaround/#comments

which is adding an empty string <‘’> to the argument.

“window.getSelection()+‘’;”

This works somehow… BUT

the text string is somehow odd… different from what one would get with copying the same selected areqa on a web page

The difference is that whole series of spaces are in the text and that certain lay-out elements of a web page generate (invisible) ASCII (a n upside down ? question mark.

As I am entering the text string in Filemaker pro I have written some stripping routine to get these unwanted text elements out.

But I am almost sure that it is my lack of knowledge of javascript text strings returned from a web browser that may make this stripping routine necessary, and that other more elegant solutions may exist.

I will be grateful for any suggestion
