I have got below XSLT which working for single grouping, however I need to have multiple grouping for my xml below:

XSLT1.0:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:strip-space elements="*"/>
  <xsl:output indent="yes"/>
  <xsl:variable name="linkURL" select="'/system/ASPX/Link.aspx?ID='"/>
  <xsl:template match="*">
    <xsl:copy>
      <xsl:copy-of select="@*"/>
      <xsl:apply-templates select="node()"/>
      <xsl:if test="self::navigation">
        <node GroupTitle="{//@GroupTitle[1]}" GroupCode="{//@GroupCode[1]}" url="{$linkURL}{//@GroupID[1]}">
          <nodes>
            <xsl:apply-templates select="node()" mode="group"></xsl:apply-templates>
          </nodes>
        </node>        
      </xsl:if>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="*[normalize-space(@GroupCode) and not(*[not(normalize-space(@GroupCode))])]"/>

  <xsl:template match="node[normalize-space(@GroupCode)]" mode="group">
    <xsl:copy>    
      <xsl:apply-templates select="@*" mode="group"/>   
      <xsl:apply-templates select="node()" mode="group"/>      
    </xsl:copy>
  </xsl:template>

  <xsl:template match="node" mode="group">     
    <xsl:apply-templates select="node()" mode="group"/>
  </xsl:template>

  <xsl:template match="*" mode="group"/>

  <xsl:template  match="@*" mode="group">
    <xsl:attribute name="{name()}">
      <xsl:value-of select="."/>
    </xsl:attribute>
  </xsl:template>
  <!-- node attributes to be deleted have an empty template each -->
  <xsl:template match="@GroupTitle" mode="group"/>
  <xsl:template match="@GroupCode" mode="group"/>
  <xsl:template match="@GroupID" mode="group"/>
</xsl:stylesheet>

Part of XML:

        </node>
    </node>
</navigation>

In above xml you will find that there are two type of GroupCode=”PB” and GroupCode=”SB”, The above XSLT code is doing only one grouping, but there can be lots of GroupCode in the xml and according to that my grouping will done. For above part XML I am looking below output:
