This can happen like so:

We decided that those XML snippets will be stored as
documents of a certain type. So, you need to decide on the
document type (a name for the type). Let's assume "cardiac
device status".

Now, you need to run the following code when the user clicks
[save] in your GUI:

        # save your XML to some temporary file
        fname = gmTools.get_unique_filename()
        xml_file = codecs.open(fname, 'w', encoding = 'utf8')
        xml_file.write(the_xml_data)
        xml_file.close()

        # import as a document
        new_doc = gmMedDocWidgets.save_file_as_new_document (
                filename = fname,
                document_type = 'cardiac device status',
                unlock_patient = False
        )

        # set some additional metadata
        new_doc['comment'] = ..
        new_doc['...'] = ...
        new_doc.save()

        # delete the temp file
        try: os.remove(fname)
        except: pass            # can raise exception on Windows

The document type will be created if it does not exist yet.
The new document will auto-appear in any listings containing
documents (EMR tree, EMR journal, document tree) across all
clients connected to the same database and showing the same
patient.
