[GRASS-dev] How can I cange or modify the GUI for watershed analysis?

[Sören Gebbert]

Hi Sandip,
i can't help you in this case. I think Google is your friend to figure
out howto redirect the output of r.watershed --interface-description
into a XML file on the command line.

I'm not sure but maybe the QGIS-GRASS package (www.qgis.org) has a
unix shell included?

You can also try to implement a Python script using subprocess and
stdout fetching to get the XML content when calling r.watershed? As
you already use WXPYTHON this should be no problem? Just make sure the
Python script is executed in the GRASS environment.

Best
Soeren
