ezxmltext: How to store and ouput your content?

One of many questions on ez.no forums is how to store and output data from ezxmltext datatype using PHP code. Here are some examples which you can use in your eZ publish scripts.

Input

Example with eZSimplifiedXMLInputParser

include_once ('lib/ezutils/classes/ezfunctionhandler.php');
// Fetch example node
$node = eZFunctionHandler::execute( 'content','node', array( 'node_id' => 2) );
$object =& $node->object();
 
include_once( 'kernel/classes/datatypes/ezxmltext/handlers/input/ezsimplifiedxmlinput.php' );
include_once( 'kernel/classes/datatypes/ezxmltext/handlers/input/ezsimplifiedxmlinputparser.php' );
include_once( 'kernel/classes/datatypes/ezxmltext/ezxmltexttype.php' );
 
// Some example content
$XMLContent = "<p>some text <b>this is bold text</b> some text <i>some text</i></p>";
 
$parser = new eZSimplifiedXMLInputParser( $object->attribute( 'id' ) );
$parser->setParseLineBreaks( true );
 
$document = $parser->process( $XMLContent );
 
// Create XML structure
$xmlString = eZXMLTextType::domString( $document );
 
// Loop through  contentobject attributes
foreach( $object->contentObjectAttributes() as $contentObjectAttribute )
{
    // Store only in  short_description attribute
    if ( $contentObjectAttribute->attribute( 'contentclass_attribute_identifier' ) == 'short_description' )
    {
        // Store XML structure in ezxmltext attribute
        $contentObjectAttribute->setAttribute( 'data_text', $xmlString );
        $contentObjectAttribute->store();
    }
}

Output

Example 1

include_once ('lib/ezutils/classes/ezfunctionhandler.php');
// Fetch example node
$node = eZFunctionHandler::execute( 'content','node', array( 'node_id' => 2) );
$object =& $node->object();
 
// Loop through  contentobject attributes
foreach( $object->contentObjectAttributes() as $contentObjectAttribute )
{
    // Get only content from short_description attribute
    if ( $contentObjectAttribute->attribute( 'contentclass_attribute_identifier' ) == 'short_description' )
    {
        include_once('kernel/classes/datatypes/ezxmltext/handlers/output/ezxhtmlxmloutput.php');
        // Get XML content from contentobject attribute
        $XMLContent = $contentObjectAttribute->attribute( 'data_text' );
        $outputHandler = new eZXHTMLXMLOutput( $XMLContent, false, $contentObjectAttribute );
        $htmlContent =& $outputHandler->outputText();
        echo $htmlContent;
    }
}

Example 2

include_once( 'kernel/classes/ezcontentobjecttreenode.php' );
 
// {def $node=fetch( 'content', 'node', hash( 'node_id', 2 ) )}
$node =& eZContentObjectTreeNode::fetch( 2 );
 
// {$node.object.data_map}
$object =& $node->object();
$dataMap =& $object->dataMap();
 
// {$node.object.data_map.short_description.content.output.output_text}
$shortDescription =& $dataMap['short_description']->content();
$shortDescriptionOutput =& $shortDescription->attribute('output');
$shortDescriptionOutputText = $shortDescriptionOutput->attribute('output_text');
 
echo $shortDescriptionOutputText;
