#3 getCdata() returns bogus results

[Josh Brown]

When returning the cdata from a xml tree the getCdata()
method applies to situations where one might have the
following:

<model>mymodel</model>

The method returns a string, which is supposed to be
the C data; in the above case it would be 'mymodel'.
This method however will always return at least a 6
character string. So in the event that someone might
do something like:

<model>tent</model> the method returns: 'tent '
which is of course incorrect.

Hope this is an easy fix.
