读取txt文件会转义所有引号

Question

我正在尝试使用以下方法读取txt文件：

set vDataFile to first file of my_location
set f to POSIX path of (vDataFile as string)
set o to (open for access (POSIX file f))
set txt to (read o for (get eof o))
close access o
return txt

向它提供这样的东西：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

返回所有引物转义：

<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>

如何防止这种情况发生？
