string - AppleScript，无法替换文本中的字符

问题描述

我正在开发一个 AppleScript，它以文件名作为参数调用 Python 脚本，例如：

set descriptionFiles to (every file of current_folder whose name extension is "txt")
repeat with textFile in descriptionFiles
   -- run a Python script that clears the xml tags and reformat the text of the file 
    do shell script "python3 '/Users/MBP/Documents/Python/cleanDescription.py' '" & textFile & "'"
end repeat

现在，只要我没有遇到名称中带有单引号的文件，AppleScript 就可以正常工作，此时它会停止并引发错误。

为了纠正这个问题，我一直在尝试在将文件名中的单引号传递给 Python 脚本之前对其进行转义，但这就是我遇到的问题。我正在使用这个例程：

on searchReplace(thisText, searchTerm, replacement)
    set AppleScript's text item delimiters to searchTerm
    set thisText to thisText's text items
    set AppleScript's text item delimiters to replacement
    set thisText to "" & thisText
    set AppleScript's text item delimiters to ""
    return thisText
end searchReplace

用这样的电话：

tell application "Finder"
    set search_T to "'"
    set rep to "\\'"
    set selected to selection as alias
    set textName to selected as text
    set res to searchReplace(textName, search_T, rep)
end tell

在单个文件上使用上面的代码会在 searchReplace(textName, search_T, rep) 部分引发错误，编号为 -1708

有任何想法吗 ？

解决方案

在 AppleScript 中转义特殊字符最可靠的方法是quoted form of. 它可以顺利处理所有形式的报价。永远不要自己做。即使quote路径不包含空格，始终成行也是一个好习惯。do shell script

另一个问题是textFile应该是 POSIX 路径而不是 Finder 说明符。并获得一次python脚本的路径

set pythonScriptPath to POSIX path of (path to documents folder) & "Python/cleanDescription.py"
set descriptionFiles to (every file of current_folder whose name extension is "txt")
repeat with textFile in descriptionFiles
    -- run a Python script that clears the xml tags and reformat the text of the file 
    do shell script "python3" & space & quoted form of pythonScriptPath & space & quoted form of POSIX path of (textFile as text)
end repeat
