applescript - 通过 iTunes 的 plist (XML) 文件访问 iTunes 中的曲目名称

Question

我了解到 iTunes XML 文件实际上是一个 plist，而不是尝试解析原始 XML，我可以使用属性列表。

我可以访问“曲目”部分，但无法执行任何简单的操作，例如提取曲目名称。诚然，我有点磕磕绊绊，但这是我到目前为止得到的代码：

tell application "System Events"
    tell property list file property_file
        tell contents
            set my_tracks to value of property list item "Tracks"
            repeat with t in my_tracks
                set theName to value of property list item "Name" of t
                display dialog theName
            end repeat
        end tell
    end tell
end tell

关于我做错了什么的任何指示？

如果有帮助，请示例 XML：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.
com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>Major Version</key><integer>1</integer>
        <key>Minor Version</key><integer>1</integer>
        <key>Application Version</key><string>9.0.2</string>
        ...
        <dict>
                <key>2471</key>
                <dict>
                        <key>Name</key><string>Check The Rhime</string>
                        <key>Artist</key><string>A Tribe Called Quest</string>
                        ...
                </dict>
                <key>2473</key>
                <dict>
                        <key>Name</key><string>A Short History of Nearly Everyth
ing (Unabridged), Part 1</string>
                        <key>Artist</key><string>Bill Bryson</string>
                        ...
                </dict>

Answer 1

当您执行 时value of property list item，AppleScript 会将整个内容转换为原生 AppleScript 值；在这种情况下，该值是一条记录。因此，您只需要稍微调整一下内部：

property property_file : ¬
    (POSIX path of (path to home folder) & ¬
        "Music/iTunes/iTunes Music Library.xml")

tell application "System Events"
    tell property list file property_file
        tell contents
            set my_tracks to value of property list item "Tracks"
            repeat with t in items of my_tracks
                display dialog (|Name| of t)
            end repeat
        end tell
    end tell
end tell

Doingitems of my_tracks生成记录值的列表；|Name| of t只是记录访问。不幸的是，执行此 plist 处理似乎很慢，因为 XML 文件非常庞大。
