Yes, by grouping the groups as I showed you.

I do not understand your concern.  Can you please post what you want 
to display for the XML content you showed us?

Perhaps the problem is in your choice of the word "grouping".  If you 
want to only show from your content all of the titles for a given 
month and page, then you do not need grouping, you only need filtering.

I hope the filtering example below helps.  It does not rely on grouping.
