Hi Adam,

I don't think it's possible to do in a single XPath. You can do:

  <xsl:for-each select="$rules/attrib"> 
    <xsl:if test="not($attribs[@name = current()/@name and
                               @state = current()/../@state])"> 
      ...
    </xsl:if> 
  </xsl:for-each> 

If the attrib elements in $attribs were held somewhere other than in a
variable, then you could construct a key for them:

<xsl:key name="attribs" match="attrib"
         use="concat(@name, ' ', @state)" /> 

And then you could do:

  $rules/attrib[not(key('attribs', concat(@name, ' ', ../@state)))]

I hope that helps,

Jeni
