How to Supress null target Elements in XSLT Mapping

Question

Hi Experts,
I need to Strip off (remove) Null tags from my ouput XML document.
My XSLT Mapping file
<?xml version='1.0' ?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<a:A2ACU>
<a:PartNo>
<xsl:value-of select="Specifications/Specification/PARTNO"/>
</a:PartNo>
<a:Revision>
<xsl:value-of select="Specifications/Specification/REVISION"/>
</a:Revision>
<a:ENERGY>
<xsl:for-each select="Specifications/Specification/Section">
<xsl:variable name="Sec_ID">
<xsl:value-of select="SECTIONID"/>
</xsl:variable>
<xsl:if test="$Sec_ID = '700015'">
<xsl:for-each select="Item">
<xsl:variable name="Item_ID">
<xsl:value-of select="ITEMID"/>
</xsl:variable>
<xsl:if test="$Item_ID = '701134'">
<xsl:for-each select="PropertyGroup/Property">
<xsl:variable name="Pro_ID">
<xsl:value-of select="PROPERTYID"/>
</xsl:variable>
<xsl:if test="$Pro_ID = '700232'">
<xsl:variable name="Atr_ID">
<xsl:value-of select="ATTRIBUTEID"/>
</xsl:variable>
<xsl:if test="$Atr_ID = '700064'">
<xsl:value-of select="STRING2"/>
</xsl:if>
</xsl:if>
</xsl:for-each>
</xsl:if>
</xsl:for-each>
</xsl:if>
</xsl:for-each>
</a:ENERGY>
</a:A2ACU>
</xsl:template>
</xsl:stylesheet>
If any one of the condition in ENRGY TAG FAILS it is giving a output as
- <A2ACU>
<PartNo>123456789</PartNo>
<Revision>2</Revision>
<ENERGY></ENERGY>
- </A2ACU>
But as per my new requirement I need to check the Empty value in all the tags and need to strip of them form final output ...like..
- <A2ACU>
<PartNo>123456789</PartNo>
<Revision>2</Revision>
- </A2ACU>
Can any one please suggest me whether any function is availble to this stripping
Thanks in Advance

Hi Ram,
try to put the tag inside the IF conditions.
It'd be something like:
> <xsl:for-each select="Specifications/Specification/Section">
> <xsl:variable name="Sec_ID">
> <xsl:value-of select="SECTIONID"/>
> </xsl:variable>
> <xsl:if test="$Sec_ID = '700015'">
> <xsl:for-each select="Item">
> <xsl:variable name="Item_ID">
> <xsl:value-of select="ITEMID"/>
> </xsl:variable>
> <xsl:if test="$Item_ID = '701134'">
> <xsl:for-each select="PropertyGroup/Property">
> <xsl:variable name="Pro_ID">
> <xsl:value-of select="PROPERTYID"/>
> </xsl:variable>
> <xsl:if test="$Pro_ID = '700232'">
> <xsl:variable name="Atr_ID">
> <xsl:value-of select="ATTRIBUTEID"/>
> </xsl:variable>
> <xsl:if test="$Atr_ID = '700064'">
> <a:ENERGY><xsl:value-of select="STRING2"/></a:ENERGY>
> </xsl:if>
> </xsl:if>
> </xsl:for-each>
> </xsl:if>
> </xsl:for-each>
> </xsl:if>
> </xsl:for-each>
