Hi Michael & Florent
Thank you for your answers.
Florent, would you be kind enough to explain the function.
<xsl:function name="k:get-source" as="xs:string">
<xsl:param name="node" as="node()"/>
<xsl:variable name="root" as="node()"
select="root($node)"/>
<xsl:choose>
<xsl:when test="$root = $north">
<xsl:text>north</xsl:text>
</xsl:when>
<xsl:when test="$root = $south">
<xsl:text>south</xsl:text>
</xsl:when>
<xsl:when test="$root = $east">
<xsl:text>east</xsl:text>
</xsl:when>
<xsl:when test="$root = $west">
<xsl:text>west</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:message terminate="yes">
<xsl:text>Unjnown source!</xsl:text>
</xsl:message>
</xsl:otherwise>
</xsl:choose>
</xsl:function>
Thanks.
