Re: conditional display of content

Thank you Andrew,

I have copied the below code into my stylesheet. and it is not
working. Can you help in getting the output. Anything i have to modify
from this.


<xsl:key name="role-by-id" match="pbl:role" use="@xml:id"/>

<xsl:template match="pbl:roleref>
 <xsl:value-of select="key('role-by-id', substring-after(@href, '#'))"/>
</xsl:template>

Regards,
Ganesh
