Attribute - 脚本函数
                此脚本函数用于返回不同媒体文件的元标签的值作为文本。支持以下格式:MP3、WMA、WMV、PNG 和 JPG。如文件 filename 不存在,则它不是一种支持的文件格式或不包含一个称为 attributename 的元标签,将会返回 NULL 值。
Attribute(filename, attributename)
可以读取大多数元标签。本主题中的示例显示了可以为相应的支持文件类型读取的标签。
信息注释根据相关规范,您只能读取保存在文件中的元标签,例如 ID2v3(MP3 文件)或 EXIF(JPG 文件),而不能读取 Windows File Explorer 中的元信息。
                参数:
| 参数 | 说明 | 
|---|---|
| filename | 
                                 如有必要,媒体文件名称包括路径作为文件夹数据连接。 示例: 'lib://Table Files/'  | 
                        
| attributename | 元标签的名称。 | 
以下示例使用 GetFolderPath 函数查找指向媒体文件的路径。因为在旧模式下仅支持 GetFolderPath,当您在标准模式或 Qlik Sense SaaS 中使用该功能时,您需要将对 GetFolderPath 的引用替换为 lib:// 数据连接路径。
示例 1: MP3 文件
此脚本读取文件夹 MyMusic 中所有可能的 MP3 元标签。
