Add a namespace to elements

Question

I have an XML document with un-namespaced elements, and I want to use XSLT to add namespaces to them. Most elements will be in namespace A; a few will be in namespace B. How do I do this?

Answer 1

With foo.xml

<foo x="1">
    <bar y="2">
        <baz z="3"/>
    </bar>
    <a-special-element n="8"/>
</foo>

and foo.xsl

    <xsl:template match="*">
        <xsl:element name="{local-name()}" namespace="A" >
            <xsl:copy-of select="attribute::*"/>
            <xsl:apply-templates />
        </xsl:element>
    </xsl:template>

    <xsl:template match="a-special-element">
        <B:a-special-element xmlns:B="B">
            <xsl:apply-templates match="children()"/>
        </B:a-special-element>
    </xsl:template>

</xsl:transform>

I get

<foo xmlns="A" x="1">
    <bar y="2">
        <baz z="3"/>
    </bar>
    <B:a-special-element xmlns:B="B"/>
</foo>

Is that what you’re looking for?
