XSLT copy from certain node with additional prefix

Question

I want to copy XML from specific node and add additional prefix for rest of the nodes. I cannot remove the parent node. Please help:

Here is my XML:

<?xml version="1.0" encoding="UTF-8"?>
    <EdiSupplierInvoiceImportEnvelope>
        <Image />
        <Attachments />

Here is XSLT:

    <xsl:output indent="yes" />
    <xsl:template match="*" >
        <xsl:element name="di:{name()}" namespace="http://schemas.datacontract.org/2004/07/Medius.PurchaseToPay.Integrations.DocumentImport">
            <xsl:copy-of select="namespace::EdiSupplierInvoice" />
            <xsl:apply-templates />
        </xsl:element>
    </xsl:template>
    <xsl:template match="EdiSupplierInvoiceImportEnvelope/InvoiceData">
        <xsl:copy>
            <xsl:apply-templates />
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

Expected results:

The second template does not match EdiSupplierInvoiceImportEnvelope/InvoiceData child nodes. It always gives me results with all nodes, not as I wanted.

Answer 1

Your first template will be used to match the root EdiSupplierInvoiceImportEnvelope and all its children, and so these will all be copied.

If you want to skip over the parent nodes, and start copying at EdiSupplierInvoice, change the second template to this...

<xsl:template match="EdiSupplierInvoiceImportEnvelope">
    <xsl:apply-templates select="InvoiceData/EdiSupplierInvoice" />
</xsl:template>
