Getting rid of empty namespaces - xslt

Question

I have the following xml:
<?xml version="1.0" encoding="UTF-8"?>
<Test xmlns="urn:hl7-org:v3" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:lab="urn:oid:7.6">
<section>
<id extension="something" root="testRoot"/>
<text>
<paragraph styleCode="somestyle">Soemthing</paragraph>
<table>
<thead>
<tr>
<th styleCode="styled">Style</th>
<th>Stuff</th>
</tr>
</thead>
</table>
</text>
</section>
</Test>
and this is the xslt:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:c="urn:hl7-org:v3"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
exclude-result-prefixes="#all">
<xsl:template match="*">
<xsl:element name="{local-name(.)}">
<xsl:apply-templates select="#* | node()"/>
</xsl:element>
</xsl:template>
<xsl:template match="#*">
<xsl:attribute name="{local-name(.)}">
<xsl:value-of select="."/>
</xsl:attribute>
</xsl:template>
<xsl:template match="/">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match = "c:section/ c:text">
<text>
<status value="generated"/>
<div xmlns="http://www.w3.org/1999/xhtml">
<xsl:apply-templates/>
</div>
</text>
</xsl:template>
</xsl:stylesheet>
This is the output:
<?xml version="1.0" encoding="UTF-8"?><Test>
<section>
<id extension="something" root="testRoot"/>
<text><status value="generated"/><div xmlns="http://www.w3.org/1999/xhtml">
<paragraph xmlns="" styleCode="somestyle">Soemthing</paragraph>
<table xmlns="">
<thead>
<tr>
<th styleCode="styled">Style</th>
<th>Stuff</th>
</tr>
</thead>
</table>
</div></text>
</section>
</Test>
As you might expect, I don't want any of those empty namespaces like in paragraph and table. I want to get rid of them so that those elements are just as they are without any namespaces but the div element should retain the namespace.
EDIT: I also would like to get rid of the attributes (including their values) for all elements under text. So that final output looks like this:
<?xml version="1.0" encoding="UTF-8"?><Test>
<section>
<id extension="something" root="testRoot"/>
<text>
<status value="generated"/>
<div xmlns="http://www.w3.org/1999/xhtml">
<paragraph>Soemthing</paragraph>
<table>
<thead>
<tr>
<th>Style</th>
<th>Stuff</th>
</tr>
</thead>
</table>
</div>
</text>
</section>
</Test>

I am guessing (!) you want to do:
XSLT 2.0
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:c="urn:hl7-org:v3"
exclude-result-prefixes="c">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="*">
<xsl:element name="{local-name(.)}">
<xsl:apply-templates select="#* | node()"/>
</xsl:element>
</xsl:template>
<xsl:template match="*" mode="xhtml" >
<xsl:element name="{local-name(.)}" namespace="http://www.w3.org/1999/xhtml">
<xsl:apply-templates select="#* | node()" mode="xhtml"/>
</xsl:element>
</xsl:template>
<xsl:template match="#*" mode="#all">
<xsl:attribute name="{local-name(.)}">
<xsl:value-of select="."/>
</xsl:attribute>
</xsl:template>
<xsl:template match="c:section/c:text">
<text>
<status value="generated"/>
<div xmlns="http://www.w3.org/1999/xhtml">
<xsl:apply-templates mode="xhtml"/>
</div>
</text>
</xsl:template>
</xsl:stylesheet>
This will place all descendants of div into the same xhtml namespace as their ancestor - resulting in:
<?xml version="1.0" encoding="UTF-8"?>
<Test>
<section>
<id extension="something" root="testRoot"/>
<text>
<status value="generated"/>
<div xmlns="http://www.w3.org/1999/xhtml">
<paragraph styleCode="somestyle">Soemthing</paragraph>
<table>
<thead>
<tr>
<th styleCode="styled">Style</th>
<th>Stuff</th>
</tr>
</thead>
</table>
</div>
</text>
</section>
</Test>
Note that this is not valid XHTML markup.
Edit
I also would like to get rid of the attributes (including their
values) for all elements under text.
Well, then don't apply templates to them:
XSLT 2.0
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:c="urn:hl7-org:v3"
exclude-result-prefixes="c">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="*">
<xsl:element name="{local-name(.)}">
<xsl:apply-templates select="#* | node()"/>
</xsl:element>
</xsl:template>
<xsl:template match="*" mode="xhtml" >
<xsl:element name="{local-name(.)}" namespace="http://www.w3.org/1999/xhtml">
<xsl:apply-templates mode="xhtml"/>
</xsl:element>
</xsl:template>
<xsl:template match="#*">
<xsl:attribute name="{local-name(.)}">
<xsl:value-of select="."/>
</xsl:attribute>
</xsl:template>
<xsl:template match="c:section/c:text">
<text>
<status value="generated"/>
<div xmlns="http://www.w3.org/1999/xhtml">
<xsl:apply-templates mode="xhtml"/>
</div>
</text>
</xsl:template>
</xsl:stylesheet>
