Actually need to know who to create the filter. I got the getChildren() part.
Like you said, that's straightforward. But what arguments does the
ContentFilter take? What types of filters can I create with it. That was what
has me stumped.

Hm, thanks. Any idea how to apply XPath in a query like this? The JCR doc
shows the Xpath args, but not how to apply them (which makes sense). I think
that if I used the XPath position() function I could achieve similar enough
results. I'm just trying to limit the amount of data I need to grab only to
display 3 or 5.
