RE: [xsl] sort; no duplicates

["Michael Kay" <michael dot h dot kay at ntlworld dot com>]

Your <city> elements are not siblings of each other, and they are
definitely not siblings of a contents element. Change

<xsl:for-each 
> select="contents/entry/city[not(.=preceding-sibling::contents/
> entry/city)]">

to

<xsl:for-each 
> select="contents/entry[not(city=preceding-sibling::entry/city)]">

Your code is going from a city element to a preceding-sibling::contents,
which is obviously wrong.
