Hello All,

How can I eliminate duplicate nodes based on values of multiple (more than 1) attributes? Also the attribute names are passed as parameters to the stylesheet. Now I am aware of the Muenchian method of grouping that uses a <xsl:key> element. But I came to know that XSLT 1.0 does not allow paramters/variables in <xsl:key>.

Is there another method(s) to achieve duplicate nodes removal? It is fine if it not as efficient as the Munechian method.

Update from previus question:

XML:

<data id = "root">
  <record id="1" operator1='xxx' operator2='yyy' operator3='zzz'/>
  <record id="2" operator1='abc' operator2='yyy' operator3='zzz'/>
  <record id="3" operator1='abc' operator2='yyy' operator3='zzz'/>
  <record id="4" operator1='xxx' operator2='yyy' operator3='zzz'/>
  <record id="5" operator1='xxx' operator2='lkj' operator3='tyu'/>
  <record id="6" operator1='xxx' operator2='yyy' operator3='zzz'/>
  <record id="7" operator1='abc' operator2='yyy' operator3='zzz'/>
  <record id="8" operator1='abc' operator2='yyy' operator3='zzz'/>
  <record id="9" operator1='xxx' operator2='yyy' operator3='zzz'/>
  <record id="10" operator1='rrr' operator2='yyy' operator3='zzz'/>
</data>
