RE: yet another XPath question

Hi Simon,

You can work off the name element and use following-sibling to check for the
existence of the address and add it if it's not there. This is not an
"XPath" solution, but it will work.

<xsl:param name="country">XLandia</xsl:param>

<xsl:template match="/resume/header/name">
    <xsl:copy-of select="."/>
    <xsl:if test="not(following-sibling::address)">
     <address>
       <country>
		<xsl:value-of select="$country"/>
       </country>
     </address>
    </xsl:if>
</xsl:template>

Hope this helps.
