Re: [xsl] producing three sets of output from one file

["Joerg Heinicke" <joerg dot heinicke at gmx dot de>]

Hello Eric,

I think it's not so difficult. In any case you need to parameterize the
stylesheet:

<xsl:stylesheet>
    <xsl:param name="audience" select="'A'"/>

    <xsl:template match="root">
        <xsl:apply-templates select="article"/>
    </xsl:template>

    <xsl:template match="article">
        <!-- .... -->
    </xsl:template>
</xsl:stylesheet>

Now you have to compare the level of $audience with the @audience of the
articles. With characters this is a bit difficult, with numbers quite easy.
So, if you can replace A with 1 and B with 2 and so on, the following will
help:

<xsl:stylesheet>
    <xsl:param name="audience" select="'1'"/>

    <xsl:template match="root">
        <xsl:apply-templates select="article[@audience &lt;= $audience]"/>
    </xsl:template>

    <xsl:template match="article">
        <!-- .... -->
    </xsl:template>
</xsl:stylesheet>

When using ABC, you have to do the replacing dynamically:

    <xsl:apply-templates select="article[translate(@audience,'ABC','123')
&lt;= translate($audience,'ABC','123')]"/>

Hope this helps,

Joerg
