You can use xsl:for-each-group and count the current-group() sequence:

  <xsl:template match="/">
     <xsl:value-of select="file/entry/@id"/>
     <xsl:text>.</xsl:text>
     <xsl:for-each-group select="file/entry/@id" group-by=".">
       <xsl:variable name="count" select="count(current-group())"/>
       <xsl:if test="$count &gt; 1">
         <xsl:value-of select="concat(current-grouping-key(), ' 
repeated ', $count, ' times.')"/>
       </xsl:if>
     </xsl:for-each-group>
  </xsl:template>
