If node is empty

Hello,

I have a project with 4 movie clips. Inside each clip there are dynamic textfields that read xml-file. My intention is to view each clip(alpha 100%) for 10-15secs at a time.

My question is how can I view only the clips that have content in their xml?

Lets call the movie clips mc1-4. If I only have text to view in the first two mc’s how do I construct some sort of IF structure:

IF mc3 doesn’t have content to view, view mc1 instead of it and then mc2 and so on.

All the movie clips read the same xml-file they just view different content from it. For example: mc1 reads 10 first nodes(with its childs), mc2 reads 11-20 and so on. That is why I want to know because it is stupid to show empty tables.

Thanks.
