Hi Carlos,

Just try to select it:

  /FAMILIAS/FAMILIA/LINKFAMILIA

That will either give you a node set of LINKFAMILIA elements or a node
set containing nothing at all. When you use a test on a node set, the
test is true if the node set contains something, and false if the node
set is empty. So you can use:

  <xsl:if test="/FAMILIAS/FAMILIA/LINKFAMILIA">
    There is a LINKFAMILIA element in the document.
  </xsl:if>

Cheers,

Jeni
