getting stuck in context when using substring-before a

I have the following simplified xml file that I am transforming into an
HTML table.  In the table I have a cell where I am placing three date
values in an embedded table.  I am having trouble using the
substring-before as a test to find the specific element that matches and
then getting that elements data.  This case is very simple, there will
be many Objects with 0 to 5 bObjRef elements, each of which will have
its own cell with 3 date values displayed.

Any guidance is greatly appreciated,
