Re: [xsl] targeting the 'first' instance of the same element in variable structures

["Jean-Paul Rehr rehrjb@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

At first Martin's solution  <xsl:template match="(div//head)[1]"> looked
like it would work. But then I started to test the various documents I have
to work with, in particular at the most problematic. Below is an actual
