XPath 2.0 dynamic generation of CSV file

[William]

Hello all,

I have an XML file that is structured similar to this:

Code: Select all

<foo>

    <bar>

        <items>

            <item/>

            <item/>

            <.../>

        </items>

        <sets>

            <set/>

            <set/>

            <.../>

        </sets>

        <items>

            <item/>

            <item/>

            <.../>

        </items>

        <sets>

            <set/>

            <set/>

            <.../>

        </sets>

    </bar>

</foo>

I also have an XSLT that I use to extract the /foo/bar/items/item elements as CSV. However, what I would really like to do is make the transformer dynamic so that I can set some params to tell it that I want to extract ./items/* or ./sets/* as CSV.

Is this doable? I would appreciate your thoughts on this please.

This is being built and tested using the IDE but will be end up in a Java application.

Hi,

It is doable, but it depends on how your XSLT is written.
Note that you can't use variables or parameters in the patterns from xsl:template/@match, but you can use them in xsl:for-each.
Here's a simple example:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

    xmlns:xs="http://www.w3.org/2001/XMLSchema"

    exclude-result-prefixes="xs"

    version="2.0">

    <xsl:param name="groupName" select="'sets'"/>

    <xsl:param name="itemName" select="'set'"/>

    <xsl:template match="/">

        <xsl:for-each select="//*[name() = $groupName]">

            <!-- Per group -->

            <xsl:for-each select="*[name() = $itemName]">

                <!-- Per item -->

                <xsl:message select="text()"/>

            </xsl:for-each>

        </xsl:for-each>

    </xsl:template>

</xsl:stylesheet>

Hi Adrian,

Thank you for that looks interesting. I'll give it a go and see what comes out in the wash.
