xsl code:

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet xmlns:dp="http://www.datapower.com/extensions" xmlns:xsl="http://www.w3.org/1999/xsl/transform" extension-element-prefixes="dp" exclude-result-prefixes="dp" version="1.0"> <xsl:template match="/">      <claimsrequest>                 <xsl:for-each select="//externalidgroup">   <xsl:variable name="accode">             <xsl:value-of select="acctcd"/>             </xsl:variable>   <xsl:variable name="accode1">        <xsl:choose>         <xsl:when test="string-length($accode) &gt; 10">                       <xsl:value-of select="substring($accode, 1,10)"/>         </xsl:when>         <xsl:otherwise><xsl:value-of select="$accode"/></xsl:otherwise>       </xsl:choose>        </xsl:variable>                            <claimdetail>                                     <accountcode><xsl:value-of select="acctcd1"/></accountcode>                                                </claimdetail>             </xsl:for-each>       </claimsrequest> </xsl:template> </xsl:stylesheet>  desired output :  <claimsrequest>      <claimdetail>           <accountcode>plan1 opti</accountcode>          </claimdetail>    <claimdetail>           <accountcode>plan2</accountcode>          </claimdetail> </claimsrequest> 

i don't understand how derived desired output input. suspect need :

<xsl:stylesheet version="1.0"  xmlns:xsl="http://www.w3.org/1999/xsl/transform"> <xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>  <xsl:template match="/">     <claimsrequest>             <xsl:for-each select="//externalidgroup">              <claimdetail>                                 <accountcode>                     <xsl:value-of select="substring(acctcd, 1, 10)"/>                 </accountcode>                                          </claimdetail>         </xsl:for-each>     </claimsrequest> </xsl:template>  </xsl:stylesheet>
