Re: [xsl] need further assistance with grouping nodes into groups of 3

Chuck,

In your 'image' template, do something like this:

<xsl:template match="image">
    <td>
        Path: <a href="{thumbimage/thumbpath}">
            <xsl:value-of select="thumbimage/thumbpath"/></a>
        Description:  <xsl:choose>
                <xsl:when test="title">
                    <xsl:value-of select="substring(title,1,25)"/>
                </xsl:when>
                <xsl:when test="description">
                    <xsl:value-of select="substring(description,1,25)"/>
                </xsl:when>
                <xsl:otherwise>
                    <xsl:value-of select="substring(id,1,25)"/>
                </xsl:otherwise>
            </xsl:choose>
    </td>
</xsl:template>

If <title> or <description> elements may be present but empty, you'll have
to use a different test, like:
        <when test="title != ''">

Good luck,
--Paul
