  • Beware of xml :)

    Shorten is a "as is" operator, and will shorten crudely your xml text, counting tags as simple text, and producing seemingly strange output.
    A solution is to use the Php strip_tags operator, as follows :
    {def $xml_content=$node.data_map.champ_xml.data_text}
{def $text_content=$xml_content|strip_tags()}
{$text_content|shorten(100)}

    In order to be able to use strip_tags, you have to add it to authorized eZ template operators. Edit the template.ini.append.php file of your siteaccess (create it if it does not exist), and add
    [PHP]
PHPOperatorList[strip_tags]=strip_tags

  • A more flexible way

    Your solution has a major problem: it destroys all the new lines and screws the layout.

    This extension allows to shorten the xml result, even while keeping all (or a selection of) xml tags.

    as an added bonus, it offers a bigger security, no matter your ez config.

  • shorten on a word boundary

    Code snippet to break on a word boundary.

    Basic strategy is to truncate the string, then add characters until you encounter a space, or run out of string.

    {def $sub=$node.object.data_map.short_description.content.xml_data
        $subsub=''
        $len=count($sub)
        $limit=598
        $chr=''
        $i=0}
{if ge($len,$limit)}
        {set $i=$limit|sub(50)}
        {set $subsub=$sub|shorten($i,'')}
        {set $chr=$sub|extract($i,1)}
        {while and(ne($chr,' '),lt($i,$limit))}
                {set $subsub=$subsub|concat($chr)}
                {set $i=$i|inc}
                {set $chr=$sub|extract($i,1)}
        {/while}
        {set $subsub=$subsub|concat(' ...')}
{/if}
