Attributes with Multiple Values
Some media item attributes can have multiple values. For example, the Author, WM/Composer, and WM/Genre attributes can each have more than one value. The data type of such attributes is multi-valued string.
In Windows Media Player, the library displays multiple values in a single field, separating the values with semicolons. However, each value is actually a separate attribute in the Windows Media item.
You can write code that will determine whether a given attribute has multiple values and then retrieve all of those values. You must use Media**.getItemInfoByType**. If you use the Media**.getItemInfo** method to retrieve a multi-valued attribute, you will only retrieve the first value.
The final example in the Reading Attribute Values topic demonstrates the use of the Media.getAttributeCountByType and Media.getItemInfoByType methods to retrieve multiple values for a given attribute.
