Re: [xsl] looking for best way to group elements

[Bill French <bfh@xxxxxxxxxxxxx>]

Hi again,

Looks like I've answered my own question.

Here's the template I wrote:

<xsl:template match="rm:group[@name = 'Languages']/rm:field[@name = 
'ppl_language']" priority="3">
    <xsl:variable name="pos" select="position()"></xsl:variable>
    <div class="group">
        <span class="meta-name">Language</span>
        <span class="meta-value"><xsl:copy-of select="./node()"/></span>
        <span><xsl:value-of select="../rm:field[$pos + 
1]/@displayName"/></span>
        <span><xsl:copy-of select="../rm:field[$pos + 1]/node()"/></span>
        <span><xsl:value-of select="../rm:field[$pos + 
2]/@displayName"/></span>
        <span><xsl:copy-of select="../rm:field[$pos + 2]/node()"/></span>
        <span><xsl:value-of select="../rm:field[$pos + 
3]/@displayName"/></span>
        <span><xsl:copy-of select="../rm:field[$pos + 3]/node()"/></span>
    </div>
</xsl:template>

If anyone can think of a more elegant solution, I'd still love to see it.

Regards,
