Question

There is any solution to add namespaces without prefix(i mean these ns0, ns1) which working on all the etree implementations or there are working solutions for each one?

For now I have solutions for:

• lxml – nsmap argument of Element
• (c)ElementTree(python 2.6+) – register namespace method with empty string as a prefix

The problem is (c)ElementTree in python 2.5, I know there is _namespace_map attribute but setting it to empty string creating invalid XML, setting it to None adding default ns0 etc. namespaces, is there any working solution?

I guess

Element('foo', {'xmlns': 'http://my_namespace_url.org/my_ns'})

is a bad idea?

Thanks for help

I have just work around for you.

Define your own prefix:

unique = 'bflmpsvz'

my_namespaces = {
                 'http://www.topografix.com/GPX/1/0' :    unique,
                 'http://www.groundspeak.com/cache/1/0' : 'groundspeak',
                }
xml.etree.ElementTree._namespace_map.update( my_namespaces )

And then, replace/remove the prefix on the output:

def writeDown(data, output_filename):

    data.write(output_filename)
    txt = file(output_filename).read()
    txt = txt.replace(unique+':','')
    file(output_filename,'w').write(txt)

Probably, there is better solution.
