Monkey patch for the Python SUDS library

def monkey_patch_suds():
    """
    Apply our monkey patch for the suds package.

    For some weird reason the location http://www.w3.org/2001/xml.xsd is used
    for the XML namespace, but the W3C seems to respond too slow on that url.
    We therefore use http://www.w3.org/2009/01/xml.xsd which fixes this.

    Call this function before importing anything from the suds package. For
    example, start your file with the following:

        import monkey; monkey.monkey_patch_suds()
        from suds.client import Client
    """
    from suds.xsd.sxbasic import Import
    _import_open = Import.open

    # Only apply the patch once.
    if getattr(Import, 'MUTALYZER_MONKEY_PATCHED', False):
        return

    def _import_open_patched(self, *args, **kwargs):
        if self.location == 'http://www.w3.org/2001/xml.xsd':
            self.location = 'http://www.w3.org/2009/01/xml.xsd'
        return _import_open(self, *args, **kwargs)

    Import.open = _import_open_patched
    Import.MUTALYZER_MONKEY_PATCHED = True

A better way might be (not tested):

from suds.xsd import sxbasic
sxbasic.Import.bind('http://www.w3.org/2001/xml.xsd', 'http://www.w3.org/2009/01/xml.xsd')
