Getting Unique values and adding the values in XSLT -


hi pretty new xslt need on simple xsl code.

my input xml 

<?xml version="1.0" encoding="ascii"?> <node name="person"  received="1"  good="1" bad="0"  condition="byperson:1111"> </node> <node name="person"  received="1"  good="1" bad="0"  condition="byperson:1111"> </node> <node name="person"  received="1"  good="1" bad="0"  condition="byperson:2222"> </node> <node name="person"  received="1"  good="1" bad="0"  condition="byperson:2222"> </node> <node name="person"  received="1"  good="1" bad="0"  condition="byperson:3333"> </node>

and expecting result sum of received , , bad need added once per unique condition.

something this

<?xml version="1.0" encoding="ascii"?> <received>3</received > <good>3</good> <bad>0</bad>

i trying below code no success far getting sum of everything, sum on each 'condition' once.

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/xsl/transform" version="1.0">   <xsl:template match="/">   <xsl:value-of select= "sum(node@received)"/> <xsl:value-of select= "sum(node/@good)"/> <xsl:value-of select= "sum(node/@bad)"/>     </xsl:template>

the following stylesheet uses xsl:key group <node> elements value of @condition. using meunchien method key() , generate-id(), select first node element each unique @condition , generate sum() of attributes of selected node elements.

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/xsl/transform"     version="1.0">     <xsl:output indent="yes"/>      <xsl:key name="nodesbycondition" match="node" use="@condition"/>      <xsl:template match="/">         <results>              <xsl:variable name="distinctnodes"                  select="*/node[generate-id() =                  generate-id(key('nodesbycondition', @condition)[1])]"/>              <received>                 <xsl:value-of select= "sum($distinctnodes/@received)"/>             </received>             <good><xsl:value-of select= "sum($distinctnodes/@good)"/></good>             <bad><xsl:value-of select= "sum($distinctnodes/@bad)"/></bad>                         </results>     </xsl:template>  </xsl:stylesheet>
