Obtaining coordinate information from collada files?

[Auslander]

I am building out a geoindexer that vacuums up a number of file types and exports holdings to geojson, feature class, etc.  I have numerous collada files with geolocation embedded according to 1.5 spec but standard GIS libraries don't handle collada.

I hate to sound so needy, but can someone provide me a simple recipe on how I can obtain that content?

I've installed pycollada without issue, but I think mine is something of an edge case as I'm not using it for construction/editing/saving.  All I'd like to do is to iterate over a file list, look for the <geographic_location> tag and then parse out the child elements.  Hopefully this is easy?

in pseudo code what i'm trying to do is like this:

model_list = [models...]

for m in model_list:
    for element in m.get('geographic_location'):
        lat = element.latitude
        lon = element.longitude
        if element.altitude_mode == "absolute":
            z_ab = element.altitude_mode
        elif element.altitude_mode == "relativeToGround":
            z_re = element.altitude_mode

Thanks for any assistance

If you just want to grab the XML content, you might consider using lxml (https://lxml.de/) or etree (https://docs.python.org/3/library/xml.etree.elementtree.html) directly.

Oh, didn't realize collada was all XML format!  Okay, I'll try that.  Thanks,
