One to One XSLT map with namespace manipulations - xslt

Question

I have the following xml:
<ns0:Root xmlns:ns0="http://root" xmlns:nm="http://notroot">
<nm:MSH>
<content>bla</content>
</nm:MSH>
<ns0:Second>
<ns0:item>aaa</ns0:item>
</ns0:Second>
<ns0:Third>
<ns0:itemb>vv</ns0:itemb>
</ns0:Third>
</ns0:Root>
That is my expected result:
<Root xmlns="http://root" xmlns:nm="http://notroot">
<nm:MSH>
<content>bla</content>
</nm:MSH>
<Second>
<item>aaa</item>
</Second>
<Third>
<itemb>vv</itemb>
</Third>
</Root>
I need to write an xslt 1.0 that perform that map.
I really doesn't have a clue how to do it, thus it seems pretty simple.
Can anyone please help ?

Answer 1

To move the elements from xmlns:ns0="http://root" namespace to default namespace.
Use:
<xsl:template match="ns0:*">
<xsl:element name="{local-name()}">
<xsl:apply-templates select="node()|#*"/>
</xsl:element>
</xsl:template>
To make http://root the default namespace add xmlns="http://root"to the stylesheet declaration.
Therefore you may try something like this:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
xmlns:ns0="http://root"
xmlns="http://root"
exclude-result-prefixes="ns0" >
<!-- Identity transform (e.g. http://en.wikipedia.org/wiki/Identity_transform#Using_XSLT -->
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()" />
</xsl:copy>
</xsl:template>
<!-- match root element and fore notroot namespace to this -->
<xsl:template match="/*">
<Root xmlns:nm="http://notroot">
<xsl:apply-templates select="#*|node()" />
</Root>
</xsl:template>
<xsl:template match="content">
<content>
<xsl:apply-templates select="#*|node()" />
</content>
</xsl:template>
<!-- move attributes with prefix ns0 to default namespace -->
<xsl:template match="#ns0:*">
<xsl:attribute name="newns:{local-name()}">
<xsl:value-of select="."/>
</xsl:attribute>
</xsl:template>
<!-- move elements with prefix ns0 to default namespace -->
<xsl:template match="ns0:*">
<xsl:element name="{local-name()}">
<xsl:apply-templates select="node()|#*"/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>

Answer 2

The only difference between your input and output is that the content element inside nm:MSH has moved from being in no namespace to being in the http://root namespace. This can be handled by an identity transformation with tweaks:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
xmlns:ns0="http://root">
<xsl:template match="#*|node()">
<xsl:copy><xsl:apply-templates select="#*|node()" /></xsl:copy>
</xsl:template>
<xsl:template match="content">
<ns0:content><xsl:apply-templates select="#*|node()" /></ns0:content>
</xsl:template>
</xsl:stylesheet>
