Change these to

<!-- delete CCC and BBB-->
<xsl:template match="CCC | BBB" />

<!-- copy DDD and modify depending on BBB-->
<xsl:template match="DDD">
  <xsl:copy>
    <xsl:copy-of select="@*"/>
    <xsl:if test="../BBB='bbb'">
      <XXX><xsl:value-of select="../BBB"/></XXX>
    </xsl:if>
    <xsl:apply-templates/>
  </xsl:copy>
</xsl:template>

and it ought work.
