I try to but had some promlems in my email acount.

If I understand you correct you want to match a node 'b' based on two
conditions. It's easier if you select only those you want instead of
matching them

Try this:
 <!-- get all 'b's -->
 <xsl:key name="Bs" match="b" use="'B'"/>
 
 <xsl:template match="root">
  <doc>
  <xsl:apply-templates select="c"/>
  </doc>
 </xsl:template>
 
 <xsl:template match="b">
  <comment>Matched B...<xsl:value-of select="@id"/></comment>
 </xsl:template>

 <xsl:template match="c">
  <xsl:variable name="src" select="c1[@role='src']/@target"/>
  <xsl:variable name="dst" select="c1[@role='dst']/@target"/>
  <!-- select the 'b' nodes with id=$src and with parent 'a' that
doesn't have another 'a' as ancestor -->
  <xsl:apply-templates
select="key('Bs','B')[@id=$src][key('Bs','B')[@id=$dst]/parent::a[not(an
cestor::a)]]"/>
 </xsl:template>


Hope this helps you.
