GNUmed plugin development - part 12

Show me the code. Part 11 talked about the xml handling. I put everything in the CVS to make it available.
That was almost two months ago. Due to time constraints I only recently picked up again. I had to realize that my python skills are very rusty and that I had to learn to read and write at the same time.

In the meantime both the XML files as well as the Parser have gone through 2 rewrites. I threw the code out where I felt it became too complex for me to handle. Check out the latest version now.

now run:
and observe the following output:
Device(ICD): St. Jude Medical Atlas DR (active)   Battery: St. Jude Medical (St. Jude Medical)  Implanted: 23.03.2002

RA-lead in RA-position: Medtronic Sprint XL (active,no comment on lead) Implanted: 23.04.2009
last check: 23.04.2004 Sensing: 7mV Threshold 1.4mV Impedance: 300 Ohm

RV-lead in RV-position: Medtronic Sprint fidelis (inactive,no comment on lead) Implanted: 23.04.2009
last check: 23.04.2009" Sensing: 7mV Threshold 1.4mV Impedance: 300 Ohm

LV-lead in LV-position: St. Jude QuickSite XL (active,no comment on LV lead) Implanted: 23.04.2009
last check: 23.03.2004 Sensing: 7mV Threshold 1.4mV Impedance: 300 Ohm
Now what you see here has been parsed from the XML. No more fake input. Next step is to first replace all hardcoded English strings with gettext-equivalents so translators can have a go at them. To achieve that we will take a look at other plugins that already have that feature.

Take a look at The first few lines look like this.

import logging

from Gnumed.wxpython import gmPlugin, gmMeasurementWidgets
from Gnumed.pycommon import gmI18N

_log = logging.getLogger('gm.ui')
All of the above but the second and third line were added to the top of the parser. To tell gettext where to replace I marked them like this:
_('this is a string that needs a translation') vs. 'this is a string that needs a translation'
So the _() construct identifies the strings to gettext. The following lines were added to the main section.
from Gnumed.pycommon import gmI18N
Running the parser now displayes the same result even after all 'I am a string' occurences having been replaced by _('I am a string'). The next part will try to get the parser connected to gmCardiacDevicePlugin and get this plugin displayed in GNUmed. Once this has been accomplished the XML needs to be read from the database instead of a file.
