return the first found element for the given DOM Path or null if not found
Mac and Linux absolute file paths begin with "/"
i.e /Users/fredbloggs/packages/index.htm
so simply prepending "file:///" to obtain a valid URL will not work because
we will end up with four forward slashes, which is an illegal URL
This method examines the file reference and if it starts with a
forward slash prepends "file://" instead of "file:///" and returns
the String result
