I want to add some prefixes, so I have applied below xslt code which got from stackoverflow and it is working fine. but with below code I am getting namespaces in node level.below is the xsl code.
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:gsk="http://apse.com">
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="GskEpcExtension|GskEpcExtension//*">
<xsl:element name="gsk:{name()}" namespace="http://epcis.gsk.com">
<xsl:copy-of select="namespace::*"/>
<xsl:apply-templates select="node()|#*"/>
</xsl:element>
</xsl:template>
<xsl:template match="StandardBusinessDocumentHeader|StandardBusinessDocumentHeader//*">
<xsl:element name="sbdh:{name()}" namespace="http://www.unece.org/cefact/namespaces/StandardBusinessDocumentHeader">
<xsl:copy-of select="namespace::*"/>
<xsl:apply-templates select="node()|#*"/>
</xsl:element>
</xsl:template>

It seems you only need to add one more template:
<xsl:template match="EPCISDocument">
<epcis:EPCISDocument xmlns:epcis="urn:epcglobal:epcis:xsd:1">
<xsl:apply-templates select="node()|#*"/>
</epcis:EPCISDocument>
</xsl:template>
I would also suggest moving all your namespace declarations to the top level element, so that eventually your stylesheet looks something like:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:epcis="urn:epcglobal:epcis:xsd:1"
xmlns:sbdh="http://www.unece.org/cefact/namespaces/StandardBusinessDocumentHeader"
xmlns:gsk="http://epcis.gsk.com">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<!-- identity transform -->
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="EPCISDocument">
<epcis:EPCISDocument>
<xsl:apply-templates select="node()|#*"/>
</epcis:EPCISDocument>
</xsl:template>
<xsl:template match="GskEpcExtension|GskEpcExtension//*">
<xsl:element name="gsk:{name()}">
<xsl:apply-templates select="node()|#*"/>
</xsl:element>
</xsl:template>
<xsl:template match="StandardBusinessDocumentHeader|StandardBusinessDocumentHeader//*">
<xsl:element name="sbdh:{name()}">
<xsl:apply-templates select="node()|#*"/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
