Debugging/deciphering library methods

Hi,

I am using the gcal zend library in Symfony using the symfony-zend
bridge plugin.

I  am successfully getting the feed of a calendar and setting the sort
order, etc.

I am having trouble rendering (or ideally, parsing to import the data
into local db). $event->title->text works, but none of the other
documented method seem to work.

I would rather not have to use dom if at all possible

Any pointers?

thanks
