[exslt] XML node replacement

[Matthew Haynes]

Hi,

Sounds like you need an XSLT tutorial, there are some great ones out there
on the web:

http://www.google.co.uk/search?q=XSLT+tutorial

I could also recommend XSLT Programmers Reference by Michael Kay. This book
is pretty much the definitive guide to XSLT and can be picked up on Amazon
fairly cheaply.

As for your problem, below is how I would do it:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="
1.0">


    <xsl:template match="/">

        <test>

            <!-- Apply templates to all <node1> nodes directly under /test/
-->
            <xsl:apply-templates select="test/node1" />

            <children>
                <!-- Apply templates to all <node1> nodes directly under
/test/descendant -->
                <xsl:apply-templates select="test/descendant::node()/node1"
/>
            </children>

        </test>

    </xsl:template>

    <!-- Match <node1> nodes -->
    <xsl:template match="node1">

        <!-- New element named after the value of doc_var_name -->
        <xsl:element name="{./@doc_var_name}">

            <!-- New element with value of doc_var_name -->
            <xsl:attribute name="doc_var_name">
                <xsl:value-of select="./@doc_var_name"/>
            </xsl:attribute>

            <!-- Copy of all child nodes-->
            <xsl:copy-of select="./child::node()" />

        </xsl:element>

    </xsl:template>

</xsl:stylesheet>

Cheers,

Matt
