assuming your input cid's are in alphabetic or numeric order... this should
work:

<xsl:for-each select="//concept[not(following::concept[1]/@cid=@cid)]">
<xsl:value-of select="@cid"/>
</xsl:for-each>

I would expect what you have already would work, but I think this is a
little bit more definite.. I don't know, but it's worth a try.

Hi Folks,
           I am just trying to get the unique values
of  an attribute and just not getting it. I had
succcess in getting the unique values for elements
with the same expression.Am i missing something or is
there a different way to get the unique values for
attributes

<xsl:for-each select="//conept/@cid[not(. =
following::concept/@cid)]">
<xsl:value-of select="."/>
</xsl:for-each>

The above statement doesnot give me the unique values
of the @cid attribute.

Thanks
Thomas
