SOAP - Beginner Desperately looking for Help

[Rodney Garland]

Hi All,

I am a relative beginner to Python and am looking for help with sending and 
XML message and getting back a return file.  The server is:

https://node.deq.state.or.us/node/node.asmx

I have have successfully sent and recieved using the PING, AUTHENTICATE 
(send in username and password and return a secuirity token), SOLICIT(send 
in information for a query and get a number indicating the query), 
GETSTATUS(status of query) using SOAPpy.  I am using Python 2.4 on a Window 
XP machine.

What I want to do now is download the result of my query using the DOWNLOAD 
method.  However, I cann't figure out how to do this.  I have tried SOAPpy 
and httplib and I cann't send the correct XML outgoing message.  Any help 
with this would be greatly appreciated.  Following is the needed outgoing 
XML file and my successful SOAPpy code.

Thank you,

Rodney (rodney_garland at hotmail.com)

Below is an example of the code that does work.

urlNode = 'https://node.deq.state.or.us/node/node.asmx?op=NodePing'
namespace = 'http://www.ExchangeNetwork.net/schema/v1.0/node.xsd'
server = SOAPProxy(urlNode, namespace)
PING = server.NodePing('Ping')

urlAuth = 'https://node.deq.state.or.us/node/node.asmx?op=Authenticate'
# AUTHENTICATE - Returns a variable with the token
server = SOAPProxy(urlAuth, namespace)
token = server.Authenticate(userId='MYUSERNAME', credential='MYPASSWORD', 
authenticationMethod='Invoke')
print token

urlSolicit = 'https://node.deq.state.or.us/node/node.asmx?op=Solicit'
server = SOAPProxy(urlSolicit, namespace)
rowID='0'
maxRows='1000'
service='GetAirMeasurements'
fieldEventStartDate='2005-01-01'
fieldEventEndDate='2005-02-01'
analyteName='PM10'
parameters=[rowID,maxRows,'','','','','','','','','','','','','','','',fieldEventStartDate,fieldEventEndDate,'',analyteName]
transID = server.Solicit(securityToken = token, returnURL = '', request = 
'GetAirMeasurements', parameters = parameters)
print transID
