I have XML that looks like below from which I want to make the VALUE
tags that are empty (ie <Value/>) default to <Value>0.00</Value> and
then I want to pull out certain values, for which I already have the
XSLT for, which is also seen below.  Can someone please help me with
how to do this?  Thanks
