Assuming the XML input is

<getMatrixOutputCllection>
<outputVar>
<level_id>1</level_id>
<assignee>jcooper</assignee>
<reg>1000</reg>
<gold>2000</gold>
<sublevel>1</sublevel>
<status>approve</status>
</outputVar>

<outputVar>
<level_id>1</level_id>
<assignee>jcooper</assignee>
<reg>1000</reg>
<gold>2000</gold>
<sublevel>1</sublevel>
<status>reject</status>
</outputVar>

<outputVar>
<level_id>1</level_id>
<assignee>jcooper</assignee>
<reg>1000</reg>
<gold>2000</gold>
<sublevel>2</sublevel>
<status>pending</status>
</outputVar>


<outputVar>
<level_id>1</level_id>
<assignee>jcooper</assignee>
<reg>1000</reg>
<gold>2000</gold>
<sublevel>3</sublevel>
<status>yes</status>
</outputVar>

<outputVar>
<level_id>1</level_id>
<assignee>jcooper</assignee>
<reg>1000</reg>
<gold>2000</gold>
<sublevel>3</sublevel>
<status>no</status>
</outputVar>


<outputVar>
<level_id>2</level_id>
<assignee>jstein</assignee>
<reg>6000</reg>
<gold>4000</gold>
<sublevel>1</sublevel>
<status>go</status>
</outputVar>


<outputVar>
<level_id>2</level_id>
<assignee>jstein</assignee>
<reg>6000</reg>
<gold>4000</gold>
<sublevel>2</sublevel>
<status>proceed</status>
</outputVar>

<outputVar>
<level_id>2</level_id>
<assignee>jstein</assignee>
<reg>6000</reg>
<gold>4000</gold>
<sublevel>2</sublevel>
<status>pending</status>
</outputVar>
</getMatrixOutputCllection>

then this XSLT stylesheet

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

  <xsl:output method="xml" indent="yes"/>
  <xsl:strip-space elements="*"/>

  <xsl:key name="lv" match="outputVar" use="level_id"/>
  <xsl:key name="sl" match="sublevel" 
use="concat(parent::outputVar/level_id, '|', .)"/>
  <xsl:template match="/*">
    <xsl:copy>
      <xsl:apply-templates select="outputVar[generate-id() = 
generate-id(key('lv', level_id)[1])]"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="outputVar">
    <xsl:copy-of select="level_id | assignee | reg | gold"/>
    <xsl:apply-templates select="key('lv', 
level_id)/sublevel[generate-id() = generate-id(key('sl', 
concat(parent::outputVar/level_id, '|', .))[1])]"/>
  </xsl:template>

  <xsl:template match="sublevel">
    <xsl:copy-of select="."/>
    <xsl:copy-of select="key('sl', concat(parent::outputVar/level_id, 
'|', .))/following-sibling::status[1]"/>
  </xsl:template>

</xsl:stylesheet>

creates the following output:

<getMatrixOutputCllection>
   <level_id>1</level_id>
   <assignee>jcooper</assignee>
   <reg>1000</reg>
   <gold>2000</gold>
   <sublevel>1</sublevel>
   <status>approve</status>
   <status>reject</status>
   <sublevel>2</sublevel>
   <status>pending</status>
   <sublevel>3</sublevel>
   <status>yes</status>
   <status>no</status>
   <level_id>2</level_id>
   <assignee>jstein</assignee>
   <reg>6000</reg>
   <gold>4000</gold>
   <sublevel>1</sublevel>
   <status>go</status>
   <sublevel>2</sublevel>
   <status>proceed</status>
   <status>pending</status>
</getMatrixOutputCllection>
