Re: [xsl] Add id to next element

["Eliot Kimber eliot.kimber@xxxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Nothing wrong with that formulationbI guess I have enough XSLT 2 brain
damage that I forget about being able to select the head of a possibly
multi-item sequence as a shortcut for the if/then/else I wrote p


I spend a lot of time (or have spent) correcting older XSLT code to use
exactly that formulation so I should really start there b&

Cheers,

E.

What's wrong with

<xsl:template match="section">
    <xsl:copy>
        <xsl:apply-templates select="@*" mode="#current" />
        <xsl:attribute name="id"
          select="(preceding-sibling::*[1][self::target]/@refid,generate-id(.
)) => head()" />
        <xsl:apply-templates mode="#current" />
    </xsl:copy>
</xsl:template>

I am assuming XSLT 3, here, but that should be a fairly safe assumption
these days.
