Re: [xsl] Fill the value for multiple element items from preceding non-empty element

[Jörg Heinicke <joerg.heinicke@xxxxxx>]

<xsl:template match="id|key">
    <xsl:choose>
        <xsl:when test="not(string(.))">
            <xsl:element name="{name()}">
                <xsl:value-of select="preceding::*[name() = name(current())
and string(.)][1]"/>
            </xsl:element>
        </xsl:when>
        <xsl:otherwise>
            <xsl:copy-of select="."/>
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>

With <xsl:element> and name() you can shorten your code as above.
