concatenating two xPaths in XSLT -

in xslt script i'm calling recursive template , want pass xpath parameter each iteration. in each iteration want concatenate child's xpath(*/) current path (please refer code). i'm using concat() function, since returns string, i'm unable use path print content of path.

<xsl:copy-of select="$path" /> <!--this requests xpath, not string--> 

so can 1 tell me how concatenate 2 xpaths or how convert string xpath.

thank you.

    <xsl:template match="/">         <xsl:call-template name="repeatable" >             <xsl:with-param name="limit" select="10" />         </xsl:call-template>     </xsl:template>      <xsl:template name="repeatable">         <xsl:param name="index" select="1" />         <xsl:param name="limit" select="1" />         <xsl:param name="path" select="@*" />          <xsl:copy-of select="$path" />          <xsl:if test="($limit >= $index)">             <xsl:call-template name="repeatable">                 <xsl:with-param name="index" select="$index + 1" />                 <xsl:with-param name="path" select="concat('*/', $path)" />             </xsl:call-template>         </xsl:if>     </xsl:template> 

while i'm waiting respond question above, here's xslt seem be trying do:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform">   <xsl:output method="text" indent="yes" omit-xml-declaration="yes"/>    <xsl:template match="@*">     <xsl:value-of select="concat(name(), ' = ', ., '&#xa;')"/>   </xsl:template>    <xsl:template match="/">     <xsl:call-template name="repeatable" >       <xsl:with-param name="limit" select="10" />     </xsl:call-template>   </xsl:template>    <xsl:template name="repeatable">     <xsl:param name="index" select="1" />     <xsl:param name="limit" select="1" />     <xsl:param name="current" select="." />      <xsl:apply-templates select="$current/@*" />      <xsl:if test="($limit >= $index)">       <xsl:call-template name="repeatable">         <xsl:with-param name="index" select="$index + 1" />         <xsl:with-param name="limit" select="$limit" />         <xsl:with-param name="current" select="$current/*" />       </xsl:call-template>     </xsl:if>   </xsl:template>  </xsl:stylesheet> 

when run on following input:

<root a1="a" a2="b">   <cont a3="c" a4="d">     <child a5="e" a6="f" />   </cont>   <cont a7="g" a8="h">     <child a9="i" a10="j">       <subchild a11="k" a12="l" />     </child>   </cont> </root> 

the result is:

a1 = a2 = b a3 = c a4 = d a7 = g a8 = h a5 = e a6 = f a9 = a10 = j a11 = k a12 = l 

is close trying do? if not, please clarify.
