SOLVED myself !
GSON Parser unable to parse my source XML which is like following

                           <subject>
                                    <subno>1</subno>
                                    <subname>A</subname>
                                    <ltp>1-1</ltp>
                                    <crd>12</crd>
                                    <sub_type>C</sub_type>
                           </subject>

So transformed the XML content from element to attributes using the following XSLT file

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">  
  <xsl:template match="@*|node()">
    <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>  
  <xsl:template match="subject">
    <subject>
      <xsl:for-each select="*">
        <xsl:attribute name="{name()}">
          <xsl:value-of select="text()"/>
        </xsl:attribute>
      </xsl:for-each>
    </subject>
  </xsl:template>  
</xsl:stylesheet>

TRANSFORMED XML

                <subject subno="AE61002" subname="SATELLITE AND INERTIAL NAVIGATION SYSTEMS" ltp="3-1-0" crd="4" sub_type="ELECTIVE- I"/> 
		<subject subno="AE61038" subname="AEROELASTICITY" ltp="3-0-0" crd="3" sub_type="ELECTIVE- I"/>
