Removing dynamically created movieclips

Question

The following dynamically creates a set of movieclips that
I'm using instead of the list component. Each clip has an embedded
text field(txt) that displays the title of an RSS feed. I have
multiple RSS feeds that I want to load however, and when a seperate
button is clicked, I want to delete the above mentioned mc's so
that they can be replaced by new ones. I have tried loading the
values into an array, then clearing the array when the button is
clicked, but the mc's still remain.

Answer 1

I thought about my methods this morning at breakfast.
Eventually, the list will grow to a size too big for the
stage. I'm going to need a container so that I can scroll through
the items at some point.
I may as well add a listener to each button created that will
load a specific container to nest the lists. When a different
button is clicked I can simply use the removedChild(container) and
get rid of the movies in one fell swoop as opposed to identifying
each one for removal. The container can easily be controlled and
scrolled using its y value as well.
I have yet to work with this but I can think of an issue
already. If I register the container at the top, my dynamic mc
lists will start there, each with an increase in y value. The top
of that container will become the limit for scrolling upwards.
How will I note a y value to indicate the bottom of the lists
for scrolling purposes? Each button will load a container with a
unique amount of mc lists.
