How to access different character styles in a single text frame.

Hi All,

I am trying to get the multiple character styles applied to the single selected text frame. Let's say, there is a text frame with contents "ABC XYZ", ABC have different character style and XYZ have different.

What I am doing here is iterating through each character and getting its character styles. So its taking a lot of time.

Is there any other way of getting number of character styles in a text frame?

Thanks for any help.
