    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

    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.
