Hi Rostom,
 Please try this stylesheet:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

   <xsl:output method="xml" indent="yes" />

   <xsl:template match="/Root">
       <Root>
           <xsl:for-each select="Item">
             <xsl:sort select="Line_No" data-type="number" />
                <New_Item>
                  <xsl:variable name="x" select="Line_No -
substring(Line_No, string-length(Line_No), 1) + 1" />
                  <Line_No><xsl:value-of select=" $x +
count(preceding::Line_No[(. - substring(., string-length(.), 1) + 1) =
$x])" /></Line_No>
	   <Line_No_Og><xsl:value-of select=" Line_No" /></Line_No_Og>	
<Amount><xsl:value-of select="Amount" /></Amount>
               </New_Item>
           </xsl:for-each>
       </Root>
   </xsl:template>

</xsl:stylesheet>
