Answer 1

There was problem with the <XSL:when> syntax , i was using ISParent which is wrong.
U have to use test.
Also no double quetion required ("") in xsl <xsl:when ISParent='*"*../../inp1:ISParent*"* = "true"'>
<xsl:choose>
<xsl:when ISParent='"../../inp1:ISParent" = "true"'>
<top:meruAccountNumber>
<xsl:value-of select="../../inp1:MERUParentAccountNumber"/>
</top:meruAccountNumber>
</xsl:when>
<xsl:when ISParent='"../../inp1:ISParent" = "false"'>
<top:meruAccountNumber>
<xsl:value-of select="../../inp1:MERUAccountNumber"/>
</top:meruAccountNumber>
</xsl:when>
</xsl:choose>
