In your example the text node "Chapter on Testing:" is indeed a 
preceding-sibling of the element node <AddText>Testing FAQ</AddText>,
so the problem must be somewhere else.

Note that preceding-sibling::* only selects elements, to select text nodes
use preceding-sibling::text(), and to select both using
preceding-sibling::node(). You probably only want the immediately preceding
sibling, which is preceding-sibling::node()[1].

However, if you select a text node then its string-length will always be >0.
Zero-length text nodes do not exist. Perhaps you really want to test for the
existence of the text node rather than its length? Fortunately, though,
string-length() applied to an empty node-set returns 0.

Better to incorporate that in the match pattern:

     match="Center//text()"

Better to write that as test="../parent::Center"

 and

As DC explained, d-o-e is not the right way to do things.
