XSL Copy nodes without xmlns

Question

I have a specific problem. I have to transform an XML structure to other, where the base XSD is same, different only the namespace definition. The first part is simple, because here I have to use field-mapping. The second part is the simple copy. And here is the problem. The copied "main" node contains the original xmlns attribute. I need to remove this "attribute".

The base xml:

        <TxId>F3232323232</TxId>
 ...

I don't want to get the xmlns:S2SCTIcf="urn:S2SCTIcf:xsd:$SCTIcfBlkCredTrf" attribute this line.

Have someone any idea?

Thank you!

Answer 1

Your issue is that

<xsl:copy-of select="$var1_SCTIcfBlkCredTrf/ns0:FIToFICstmrCdtTrf/sw8:CdtTrfTxInf" />

copies the node from the original tree including its "namespace nodes", i.e. the namespace declarations that were in scope at that point in the original document. When this node is serialized any of these namespace nodes that are not already in force at this point in the output document will be declared by the serializer.

If you were able to use XSLT 2.0 then you could try setting copy-namespaces="no" on the copy-of but that isn't an option in XSLT 1.0. So instead of using copy-of you need to use templates to copy that node (and all its descendants recursively) without including the namespace nodes. The simplest way I can think of to do this is to declare two additional templates

<xsl:template match="*" mode="copy">
  <xsl:element name="{name()}" namespace="{namespace-uri()}">
    <xsl:apply-templates select="@*|node()" mode="copy" />
  </xsl:element>
</xsl:template>

<xsl:template match="@*|text()|comment()" mode="copy">
  <xsl:copy/>
</xsl:template>

and then replace that copy-of with

<xsl:apply-templates mode="copy"
   select="$var1_SCTIcfBlkCredTrf/ns0:FIToFICstmrCdtTrf/sw8:CdtTrfTxInf" />

The trick here is that xsl:element is creating a new element node that happens to have the same name and namespace as the original one, rather than copying the original node, so it doesn't copy the namespace nodes.
