Re: [xsl] generalized unique element

["Laura Jenkins" <xsl_list@xxxxxxxxxxx>]

Thanks david that was superb,
as u had suggested
I tried using the keys and was successful ( i referred to jeni's article )
the following is what i did..
<xsl:key match="*" use="name(.)" name="all-nodes"/>
..
...
....
.....
......
<xsl:if test="count(.| key('all-nodes', name(.))[1]) = 1">

It works fine, i however do not understand what goes on in the above line..
I would be thankful if u can please explain me the
1.use of count in the above statement.
2.especially the use of key('',xx)[1] above ..

same with doing
<xsl:if test="generate-id() = generate-id(key('all-nodes', name(.)[1])">
i understand the use of generate-id() but do not understand
key('',xx)[1]

Thanks for your help
