RE: [xsl] testing element's contents

["Andrew Welch" <awelch at piper-group dot com>]

Couldn't you just count the number of child nodes (including text()) and
then test for img/a?

something like:

<xsl:choose>
  <xsl:when test="count(child::node()) = 1 and (child::img or
child::a)">
    <xsl:copy-of select="child::*"/>
  </xsl:when>
  <xsl:otherwise>
    <xsl:copy-of select="."/>
  </xsl:otherwise>
</xsl:choose>

cheers
