Is it possible to get/generate the XPath, for a text selected in the HTML page. Say,I have opened an html file using a browser,say safari/firefox, now i select some text (using mouse), i want to generate/get the xpath for that. is it possible to get it programatically? how?

Some years ago I wrote the following sample and tested it to work with Mozilla and with Opera. It stores the selection in a cookie and can restore the selection from that cookie. It generates and stores an XPath expression to the startContainer and endContainer of the selected range and the numbers of the offset.
