Do I correctly understand that the XML tree you are generating is the
status xml ?

The same way. Just create a JX Template that creates your XML status
information,
passing any variables as business objects. Then you open an output
stream and process
the pipeline to it:

if( somecondition ){
    var xml_output = new java.io.FileOutputStream( "filename.xml" );
    cocoon.processPipelineTo( xml_uri, { data:data } , xml_output );
}
if( othercondition ){
    cocoon.sendPage( xml_uri );
}

That way, you can use the same pipeline to deliver the status.xml to the
client or create
some file in a directory or both. IMHO, creating an XML tree in
flowscript is wrong design,
since that is what JX Templates and Pipelines are for. The purpose of
flowscript is just
to control the application flow, it should generally not be used to
perform complex
operations.

Johannes
