4.3.4.1 Rendering Markup

Render objects of type com.coremedia.xml.Markup by including them from a FreeMarker template using:

<@cm.include self=self.text/>

This uses the class XmlMarkupView as a default view, which converts richtext to XHTML applying the following transformations:

internal links are converted to URIs pointing back into the CoreMedia CAE
links (href attributes in the xlink namespace) without protocol and server are URL encoded
anchor and image elements with xlink href attributes are converted to XHTML a href and img src.
the CoreMedia richtext namespace is dropped from the elements

If you want to use your own transformations you have to proceed as follows:

Define your own view, plain for example, using a Customizer:

<customize:append id="addMarkupView"
                  bean="programmedViews">
  <map>
    <entry key="com.coremedia.xml.Markup#plain">
      <bean ..../>
    </entry>
  </map>
</customize:append>

Use XmlMarkupView as the implementation of the view, but apply a custom filter factory which creates a SAX filter chain per output. Proceed as follows:

Let your filter factory extend RichtextToHtmlFilterFactory.
Overwrite #createFilters and append your own transformations before super.createFilters.

public List createFilters(HttpServletRequest req,
  HttpServletResponse res, Markup markup, String view) {

  List result = new ArrayList();
  result.add(new MyFilterForRichtext());
  result.addAll(super.createFilters(req, res, markup, view));
}

Configure your filter factory in cae-views.xml as follows:

<entry key="com.coremedia.xml.Markup#plain">
  <bean class="com.coremedia.objectserver.web.XmlMarkupView">
    <property name="xmlFilterFactory">
      <bean class="com.coremedia.objectserver.web.
      MyRichtextToHtmlFilterFactory">
        <property name="idProvider" ref="idProvider"/>
        <property name="linkFormatter" ref="linkFormatter"/>
      </bean>
    </property>
  </bean>
</entry>
