The following shell script may be useful to help build your schema by
re-using the base AIXM namespace in the same way as the OpenGIS ones are
re-used.
if [ ! -f aixm.py ] ; then
pyxbgen \
--uri-content-archive-directory aixm.downloaded \
--archive-path '&pyxb/bundles/opengis//:+' \
--schema-location
http://www.aixm.aero/gallery/content/public/schema/5.0/AIXM_Features.xsd \
--archive-to-file aixm.wxs \
--module aixm
fi
if [ ! -f saa.py ] ; then
pyxbgen \
--uri-content-archive-directory saa.downloaded \
--archive-path '.:&pyxb/bundles/opengis//:+' \
--archive-to-file saa.wxs \
--schema-location
http://wendell-y.rho.net/aixm/SAA_AIXM_5_Schemas/SAA-Message.xsd \
--module saa
fi
The following python script, when used with PyXB 1.1.1, should help
locate problems like the unhandled SUA namespace content:
import pyxb
import urllib2
import saa
xml =
urllib2.urlopen('http://wendell-y.rho.net/aixm/SAA_AIXM_5_Schemas/sample-Snowbird.xml').read()
try:
order = saa.CreateFromDocument(xml)
print order
except pyxb.UnrecognizedContentError, e:
loc = e.content.location
print 'Unrecognized %s at %s line %d column %d' % (e.content.name,
loc.locationBase, loc.lineNumber, loc.columnNumber)
I get something like the following when running it:
Unrecognized (u'urn:us:gov:dot:faa:aim:saa:sua', u'AirspaceExtension')
at None line 79 column 6
