[r1ngx]

I would like to adapt the following NewsRack plug-in applescript to save the .html that is generated to a directory on the hd. Thanks in advance for any help.

tell application "NewsRack"
	set article_url to url of selected tab
	if article_url is "" then
		display dialog "No article selected." buttons {"OK"}
		return
	end if
	if article_url starts with "http://www.instapaper.com/m?" then
		return -- we are already on an Instapaper page
	end if
	
	set encoded_url to escape article_url
	set instapaper_url to "http://instapaper.com/m?u=" & encoded_url
	
	if kind of selected tab is "news" then
		do JavaScript "document.location.href = '" & instapaper_url & "'"
	else
		set url of selected tab to instapaper_url
	end if
end tell
