    List documents grouped by first letter

    I  have around 300 documents in my content tree which I would like to group by first letter i.e.

    A

    Adams, Alister

    B

    Barry, Barnes,Belfry

    C

    Chad, Chester

    etc...

    I have  written some xslt which takes a letter as a parameter and will output the docs for that letter, however I need to call it 26 times (once for each letter) which doesn't sit well with me!

    Are there any XSLT gurus out there who can shed some light on a best practice way of doing this?

    There are some grouping samples and threads available, see http://our.umbraco.org/forum/developers/xslt/2988-Help-grouping-and-sorting-by-category

    Or take a look into the grouping example here: http://blackpoint.dk/umbraco-workbench/xslt/grouping--distinct-values.aspx?p=3

    Here is an example I use for a glossary listing

    <xsl:for-each select="$currentPage/node">
<xsl:sort select="@nodeName" />
    <xsl:variable name="Init" select="substring(./@nodeName,1,1)"/>
    <xsl:if test="not(preceding-sibling::*[substring(./@nodeName,1,1)=$Init])">
        <div id="{$Init}" class="terms">
            <h3><xsl:value-of select="$Init"/></h3>
            <dl>
            <xsl:for-each select="../node[substring(./@nodeName,1,1)=$Init]">
                <dt id="{@urlName}"><xsl:value-of select="@nodeName"/></dt>
                <dd><xsl:value-of select="./data [@alias='definition']" disable-output-escaping="yes" /></dd>
            </xsl:for-each>
            </dl>
            <a href="javascript:window.scrollTo(0,0)">Back to top</a>
        </div>
    </xsl:if>
</xsl:for-each>

    It basically takes the first letter of the node name and uses that to find all siblings that start with the same

    You could also organise the docs in "alphabet folders" in the backend for the benefit of admins using something like http://our.umbraco.org/projects/developer-tools/autofolders, then the xslt becomes very simple as a side-result

    Hi bayshield,

    If you already have the code for finding and writing, then you can use this setup to do the alphabet-walk:

       <xsl:variable name="letters" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'" />

    <xsl:template match="/">
        <ul>
            <xsl:call-template name="writeIndex" />
        </ul>
    </xsl:template>

    <xsl:template name="writeIndex">
        <xsl:param name="index" select="1" />
        <xsl:call-template name="writeNodesForLetter">
            <xsl:with-param name="letter" select="substring($letters, $index, 1)" />
        </xsl:call-template>
        <xsl:if test="not($index = string-length($letters))">
            <xsl:call-template name="writeIndex">
                <xsl:with-param name="index" select="$index + 1" />
            </xsl:call-template>
        </xsl:if>
    </xsl:template>

    <!-- Template for nodes replace with own code -->
    <xsl:template name="writeNodesForLetter">
        <xsl:param name="letter" />
        <li>
            <xsl:value-of select="$letter" />
        </li>
    </xsl:template>

    Thanks for the input guys!  Sean's XSLT worked a treat!

    Hey just thought I'd add a little appreciation for Seans code too. Just adapted it for a similar purpose (although I'm using all tags in a group as my list source) and it works a treat. Wicked! Thanks.
