xslt - choosing specific column value from the input xml -

i have below xml input have xsl transformation

<emml>     <tradeeventheader>         <tradeidentifier>             <tradeid>104823343913</tradeid>             <systemreference>rds</systemreference>             <systemdomainname>internal</systemdomainname>         </tradeidentifier>         <tradestateidentifier>             <tradestateid>validated</tradestateid>             <systemreference>rds</systemreference>             <tradestateidclassificationscheme>vn state</tradestateidclassificationscheme>         </tradestateidentifier>         <tradestateidentifier>             <tradestateid>pending</tradestateid>             <systemreference>swapswire</systemreference>             <tradestateidclassificationscheme>mang state</tradestateidclassificationscheme>         </tradestateidentifier>         <tradestateidentifier>             <tradestateid>accpt_novated_sw</tradestateid>             <systemreference>rds</systemreference>             <tradestateidclassificationscheme>clearing state</tradestateidclassificationscheme>         </tradestateidentifier>     </tradeeventheader>     <emmlextension systemid="rds yto">         <emmlmediumstring idref="legid1" name="roll date option">short initial</emmlmediumstring>     </emmlextension> </emml> 

as shown above in input xml objective identify value of tradestateidclassificationscheme parameter , if value of parameter equal 'clearing state' correspond have check value of column tradestateid , if value of column tradestateid starts accpt_novated_sw in case need return true string , rest other need return false string ..

i have come below template in xslt 1.0 , please advise correct approach..

calling template :-

<isclearednovated>             <xsl:call-template name="cleared_novated">             <xsl:with-param name="tradestateid" select="emml/*/*/tradestateidentifier" />             </xsl:call-template>             </isclearednovated>   called template :-          <xsl:template name="cleared_novated">         <xsl:param name="tradestateid" />          <xsl:for-each select="$tradestateid/tradestateidclassificationscheme">             <xsl:choose>             <xsl:when test="$tradestateid[starts-with(tradestateidclassificationscheme,'accpt')] , systemreference='rds'">                 <xsl:value-of select="'true'"/>             </xsl:when>             <xsl:otherwise>                 <xsl:value-of select="'false'"/>             </xsl:otherwise>         </xsl:choose>         </xsl:for-each>   </xsl:template> 

i don't understand, needs are, xslt not want - suspect nothing...

so maybe can start suggestion below , can tell, has refined:

<?xml version="1.0" encoding="utf-8"?> <xsl:transform xmlns:xsl="http://www.w3.org/1999/xsl/transform" version="1.0">   <xsl:output method="text"/>    <xsl:template match="/">     <xsl:apply-templates select="//tradestateidclassificationscheme"/>   </xsl:template>    <xsl:template match="tradestateidclassificationscheme[                             . = 'clearing state' ,                              ../tradestateid = 'accpt_novated_sw' ,                             ../systemreference = 'rds'                             ]">     <xsl:value-of select="concat(.,': true&#x0a;')"/>   </xsl:template>    <xsl:template match="tradestateidclassificationscheme">     <xsl:value-of select="concat(.,': false&#x0a;')"/>   </xsl:template>     <xsl:template match="@*|*"/> </xsl:transform> 

you find 2 templates dealing tradestateidclassificationscheme, 1 matches conditions, , 1 others.

note didn't write contents of systemreference, while trial template addresses element. therefore, added condition well.

the output in version is:

vn state: false mang state: false clearing state: true
