Mike - I think the NOT will guarantee empty output:

<xsl:variable name="conhijos" select="mercados/mercado[not(subyacentes/*)]"/>


Shouldn't it be:

<xsl:variable name="conhijos" select="mercados/mercado[subyacentes/*]"/>


?

You want: 
 
<xsl:variable name="conhijos" select="mercados/mercado[not(subyacentes/*)]"/>

Close. The selected set will contain only 'mercado' elements,
not 
their parent 'mercados', so when you iterate over them, you'd
use 
select="$conhijos/subyacentes/subyacente"
