Actionscript 3 :: Show Image Within Text In Same Line?

I would like to show some images and text in the same line. The text and image is completely dynamic. At first I thought to use htmlText property of TextField as img tag is supported. Something like this:

var tf:TextField = new TextField();
tf.htmlText = "before img <img src='img.png'> after image";
addChild(tf);

But I found that the image is showing in the next line, not in the middle of two text segments. Then after checking the manual of TextField I have found that this is the documented behavior that the image will be shown on the line following the img tag.

So what is the best way to do this? Note that the text and position of images are completely dynamic.

I understand that it is possible to split the input in a series of texts and images and then position them calculating the text and images width. In other words parse the input ourselves.

Is there any better way to do this? Or is there any library available that does this parsing?
