XSL sort expression for bibliography

["William Sporrong" <wille@tegenaria.com>]

Hello,

I'm trying to sort my bibliography according to author surname. First of all I don't know where to put the sort code(<xsl:sort>)? I first tried putting it inside the  match="bibliography" (biblio.xsl) template inside <xsl:apply-template/>. This sorts the entries but not the numbers?!?

 

Second question is about XSL if someone could help me phrase a proper XPath query to use in with the <xsl:sort>. This is how I want to sort: 

    ./author/surname

        or (if it does not exist)

    ./authorgroup/author/surname 

        or (if it does not exist)

    ./biblioset[@relation='journal']/author/surname

        or (if it does not exist)

    ./biblioset[@relation='journal']/authorgroup/author/surname

        or (if it does not exist)

    ./title

 

To make it even more complicated the author names are not sorted in the bibliography so I also need a way to find the alphabetical first surname in every case.
