Now the method getSourceCode uses portal transforms if it exists otherwise we return the source code itself without conversion. We use portal_transform in order to transform python script to html if the portal skin is View or to xml if the portal skin is ODT. If the portal skin is ODT so we have the content.xml from the odt file and parse this file to retreive the adéquate code
