Hi Rüdiger,
what a crude stuff ;-))
But it works like a charm now :-)
Though, first I had to rewrite all the contents so that the mapping takes
place.
It's not important, but is there any known reason, why it is not possible to
get the value of the field with the long (the xml content date field) as
part of the extraction content?
Is it because the long is not considered to have any sound or useful textual
representation :)
public class CmsDocumentXmlContent extends A_CmsVfsDocument {
.
.
.
/**
* String org.opencms.xml.types.I_CmsXmlContentValue.getPlainText(CmsObject
cms)
* Returns the value of this XML content node as a plain text String.
*
* Plain text in this context means a pure textual representation of the
content (i.e. without html tags).
* The plain text may be null, too, if there is no sound or useful textual
representation (i.e. color values).
*
*
* Parameters:
* cms an initialized instance of a CmsObject
* Returns:
* the value of this XML content node as a plain text String
*/
String extracted = value.getPlainText(cms);
.
.
.
Anyway, thanx a lot!
Kind regards, Bernd
