I did not succeed in on-the-fly loading data from an xml-buffer and subsequently executing its content. The accompanying minimal example of a <document> shows what I strive to accomplish. The node <buffer> contains the buffered data (abc meant to be set in bold) and node <getbuffer> executing the typesetting. As can be seen the output the <b>xyz</b> outside <buffer> is correctly set in bold, but the contents of <buffer> is not processed: the xml is just reproduced. Obviously there is some misunderstanding on my part. I would like to be pointed in the right direction.
