RE: Processing an element only if there are no better

Thanks Juergen,

Problem is that Type1 is not what the actual value is.  The possible values
are (in the order of preference)

Media Release
Assessment
Reaction
Citation

Problem is, the system that generates the XML will spit these out in a
random order, so I can't rely on the one I want to appear first, nor can I
sort them due to the text order.

Hi Dave,

<snip>

Inside a template use: select="/ProductGroup/Product[1]".
Selecting the first product in document order.

Please,
