Yes!!!

I have tried it out with both the code which you posted, and the code which
David posted, so thank you both very much.

Alex.

This variation of the identity template should do what you need:

<xsl:param name="pageName" select="'manhattan'"/>

<xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:copy-of select="@*"/>
      <xsl:if test="descendant-or-self::*[@name = $pageName]">
        <xsl:apply-templates select="node()"/>
      </xsl:if>
    </xsl:copy>
</xsl:template>

It basically will output the current node, then only continue processing
it's children if a descendent of the current node has an attribute with
the required attribute.  It's not that efficient as it walks the
descendant axis for every node, but if your tree isn't that deep it
shouldn't be too bad.
