input xml -

    <?xml version = "1.0" encoding = "utf-8"?>     <root>         <input>             <c2>                 <c3>                     <c4>c4</c4>                 </c3>             </c2>         </input>         <output>             <c5>                 <c6>                     <cn>                         <t1></t1>                         <t2></t2>                     </cn>                 </c6>                 <c6>                     <cn>                         <t1></t1>                         <t2></t2>                     </cn>                 </c6>             </c5>         </output>     </root> 

desired output xml-

    <root>     <output>             <c5>                 <c6>                 <!-- have child node. putting example cn child node name.-->                     <cn>                         <t1></t1>                         <t2></t2>                         <c3>                             <c4>c4</c4>                             <newnode>current number of cn node 1</newnode>                             <newnode1>total number of c6 nodes 2.</newnode1>                         </c3>                     </cn>                 </c6>                 <c6>                     <cn>                         <t1></t1>                         <t2></t2>                         <c3>                             <c4>c4</c4>                             <newnode>current number of cn node 2</newnode>                             <newnode1>total number of c6 nodes 2.</newnode1>                         </c3>                     </cn>                 </c6>             </c5>         </output>     </root> 

thank in advance.

use following stylesheet:

<?xml version="1.0" encoding="utf-8" ?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform">   <xsl:output method="xml" encoding="utf-8" indent="yes" />    <xsl:template match="c6/*">     <xsl:copy>         <xsl:variable name="v1" select="count(../preceding-sibling::*)+1"/>         <xsl:variable name="v2" select="count(../../*)"/>         <xsl:apply-templates/>         <xsl:apply-templates select="../../../../input/c2/c3">           <xsl:with-param name="v1" select="$v1"/>           <xsl:with-param name="v2" select="$v2"/>         </xsl:apply-templates>     </xsl:copy>   </xsl:template>    <xsl:template match="c3">     <xsl:param name="v1"/>     <xsl:param name="v2"/>     <xsl:copy>       <xsl:apply-templates/>       <newnode><xsl:value-of select="$v1"/></newnode>       <newnode1><xsl:value-of select="$v2"/></newnode1>     </xsl:copy>   </xsl:template>    <xsl:template match="input"/>    <xsl:template match="@*|node()">     <xsl:copy><xsl:apply-templates select="@*|node()"/></xsl:copy>   </xsl:template> </xsl:stylesheet>
