xsl:sort affects the order in which the nodes are processed. It does not
affect the position of the nodes on any axis, such as the following-siblings
axis.

>   <xsl:for-each select="//foo">
>     <xsl:sort/>
>     <xsl:value-of select="."/>:<xsl:for-each 
> select="preceding-sibling">

Indeed you don't. What you are doing here is to ask for all child elements
(of foo) with the name "preceding-sibling". What you presumably wanted was
all preceding sibling elements of the foo element. To get that, write
select="preceding-sibling::*"
