Re: optional children

Hi Andrew,

In other words, you want to output <foo> if it has a child <b> and it
doesn't have any other children that are not <c> and <d>:

<xsl:template match="a">
  ...
  <xsl:if test="b and not(*[not(self::c or self::d)])">
    <foo />
  </xsl:if>
  ...
</xsl:template>

I hope that's what you were after.

Cheers,

Jeni
