Re: Selecting distinct values from different node in XPATH 1.0

That kind of errors are never nice....

If the problem is that set:distinct is returning a resulttree-fragment then
it might help wrapping the variable in common:node-set()  before using 
it e.g.;
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
version="1.0"
    xmlns:common="http://exslt.org/common"
    ... >
...
<xsl:for-each select="common:node-set($var-returned-by-distinct-function)">
....
<xsl:for-each>



Best regards
