Re: XSL/XPath Dynamic sort key

} <xsl:sort

\ isn't Xpath: you want /
As it is you should get a syntax error.

yes because * is multiplication.

No, concat produces a string, so it's the same as
<xsl:sort select="'author/last_name'" />
which is a legal expression, but not what you want.

<xsl:sort select="*[name()=$sort_select]|author/*[name()=$sort_select]" 
data-type="{$sort_data_type}" order="{$sort_order}" />

and just set the sort_select param to be 'uid' or 'last_name' or whatever
you want. In each case one branch of the | will return nothing, but
that's OK.
