从pbcopy获取结果,用applescript将它们转换为数组?

set locations to paragraphs of (read (choose file with prompt "Pick text file containing urls"))
repeat with aLocation in locations
    tell application "Safari" to open location aLocation
end repeat

如何从pbcopy(从Command-C操作复制的结果)读取内容?我试着如下,但我不能得到的行,但字母表。

try
    set the locations to Unicode text of (the clipboard as record)
on error errMsg
    display dialog errMsg
end try
