Getting rid of namespace added to the inner element <i>,<b>, <mpval> - xslt

Question

Namespace getting added to the inner element <i>,<b>, <mpval>. I want to get rid of this namespace.
My XML:
<Container xmlns="http://www.sss.org/schema/"
xmlns:meta="http://www.sss.org/schema/tangier/metadata">
<cs-properties>
My Parent level text 1
<mp>
text1 of first child <b> in bold</b>
<mpval>36-37</mpval>
text2 of child <i> in italic </i>
</mp>
My Parent level text2 in <i>italic</i> also in <b>bold </b>
</cs-properties>
</Container>
When I apply below XSL, I get namespace added to <i> element. Want to get rid of it.
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:sub="http://www.sss.org/schema"
exclude-result-prefixes="xsl sub">
<xsl:variable name="ns" select="'http://www.sss.org/schema/'" />
<xsl:output indent="no" omit-xml-declaration="yes"/>
<xsl:variable name="inlineElements" select="'b','i','sub','sup'"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="sub:cs-properties">
<!--<properties xmlns= "{$ns}">-->
<xsl:element name="cs-properties" namespace="{$ns}" >
<xsl:for-each-group select="node()" group-adjacent="self::text() or self::node()
[name()=$inlineElements]">
<xsl:choose>
<xsl:when test="current-grouping-key()=true()">
<parenttext>
<xsl:copy-of select="current-group()" copy-namespaces="no" />
</parenttext>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="."/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
<!--</properties>-->
</xsl:element>
</xsl:template>
<xsl:template match="sub:mp|sub:abs-max">
<xsl:element name="{name()}">
<xsl:for-each-group select="node()" group-adjacent="self::text() or self::node()
[name()=$inlineElements]">
<xsl:choose>
<xsl:when test="current-grouping-key()=true()">
<childtext>
<xsl:copy-of select="current-group()" copy-namespaces="no"/>
</childtext>
</xsl:when>
<xsl:otherwise>
<!--<xsl:apply-templates select="."/>-->
<xsl:copy-of select="current-group()" copy-namespaces="no"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
Result:
<Container xmlns="http://www.sss.org/schema"
xmlns:meta="http://www.sss.org/schema/tangier/metadata"><cs-properties><parenttext
xmlns="">
My Parent level text 1
</parenttext><mp xmlns=""><childtext>
text1 of first child <b xmlns="http://www.sss.org/schema"> in
bold</b></childtext><mpval xmlns="http://www.sss.org/schema">36-
37</mpval><childtext>
text2 of child <i xmlns="http://www.sss.org/schema"> in italic </i>
</childtext></mp><parenttext xmlns="">
My Parent level text2 in <i
xmlns="http://www.sss.org/schema">italic</i> also in <b
xmlns="http://www.sss.org/schema">bold </b></parenttext></cs-
properties></Container>

Answer 1

You can avoid the <parenttext xmlns=""> either by using <parenttext xmlns="http://www.sss.org/schema/"> in your markup or by putting xmlns="http://www.sss.org/schema/" on the styleheet's root element. The latter would affect all result elements which might be needed if you have them in more places in the stylesheet.
