RE: breaking sorted material into subsections

Hi Eric,

translate() would be a good guess I think ...
http://www.w3.org/TR/xpath#function-translate

<xsl:when test="translate($initial,'1234567890@#','')=''">

means: translate the given characters to '' (delete them) and leave all 
others as they are. (not tested ...)

Hmm, don't know what you are trying to do, but you can't create literal
output elements inside of xsl:apply-templates.
Could it be that you don't need xsl:apply-templates at all here?

>           <p><a href="{../@location}"><xsl:value-of
> select="@entry"/></a></p>
>         </xsl:for-each>
>       </xsl:otherwise>
>     </xsl:choose>
>   </xsl:for-each>
> </xsl:template>

Hope that helps,
