使用python读取非xml格式的plist文件

Question

我正在读取plist（propertly list）格式的MacOS数据，它不是XML格式，不是二进制格式，而是其他ascii格式。例如：

addr= {
    City = "San Francisco Bay Area";
}

我试图把它解析成一个Python字典。不幸的是，plistlib.loads在我试图解析它时返回InvalidFileException()：

^{pr2}$

产生：

Traceback (most recent call last):
  File "x.py", line 9, in <module>
    print( plistlib.loads( plist ) )
  File "/Users/simsong/anaconda/lib/python3.6/plistlib.py", line 1024, in loads
    fp, fmt=fmt, use_builtin_types=use_builtin_types, dict_type=dict_type)
  File "/Users/simsong/anaconda/lib/python3.6/plistlib.py", line 1009, in load
    raise InvalidFileException()
plistlib.InvalidFileException: Invalid file

正确的方法是什么？在

你说的是JSON格式的plist文件。你的例子不是JSON。在

让我们从这个开始sample plist in XML

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist SYSTEM "file://localhost/System/Library/DTDs/PropertyList.dtd">
<plist version="1.0">
<dict>
    <key>Author</key>
    <string>William Shakespeare</string>
    <key>Lines</key>
    <array>
        <string>It is a tale told by an idiot,</string>
        <string>Full of sound and fury, signifying nothing.</string>
    </array>
    <key>Birthdate</key>
    <integer>1564</integer>
</dict>
</plist>

并将其转换为JSON格式：

^{pr2}$

现在，您可以使用JSON库来阅读本文。在

import json

plist_text = '{"Author":"William Shakespeare","Birthdate":1564,"Lines":["It is a tale told by an idiot,","Full of sound and fury, signifying nothing."]}'

plist = json.loads(plist_text)

print('The author is ' + plist['Author'])

输出：

$ python3 plist.py 
$ The author is William Shakespeare
