Python mechanize - get file from aspnetForm submitControl that starts file upload

How to use python mechanics to extract a file from an aspnetForm submitControl that starts loading an Excel file when I don't know the file URL or file name?

Excel website URL: http://www.ncysaclassic.com/TTSchedules.aspx?tid=NCFL&year=2012&stid=NCFL&syear=2012&div=U11M01

I am trying to upload a file downloaded using Print Excel 'button'.

So far I:

r = br.open('http://www.ncysaclassic.com/TTSchedules.aspx?tid=NCFL&year=2012&stid=NCFL&syear=2012&div=U11M01')
html = r.read()

# Show the html title
print br.title()

# Show the available forms
for f in br.forms():
    print f

br.select_form('aspnetForm')
print '\n\nSubmitting...\n'
br.submit("ctl00$ContentPlaceHolder1$btnExtractSched")

print 'Response...\n'
print br.response().info()
print br.response().read

print 'still alive...\n'

for prop, value in vars(br.response()).iteritems():
    print 'Property:', prop, ', Value: ', value

print 'myfile...\n' 

myfile = br.response().read

and I get this output:

    Submitting...

I seem to be very close ... Pay attention to Content-Type: application / vnd.ms-excel

I just don’t know what to do next. Where is my file and how do I get a pointer to it and save it locally for access later?

Update:

dir(), / (), ...

print '\ndir(br.response())\n'
for each in dir(br.response()):
    print each

print '\nresponse info...\n'
print br.response().info()

print '\nresponse geturl\n'
print br.response().geturl()

...

dir(br.response())
