SOAP - Beginner Desperately looking for Help

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@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

Use wsdl2py(.py). It come with e.g. ZSI, but SOAPpy also use wsdltools -
which should include it. There is a WSDL given at the site, passing it
to wsdl2py results in type-definitions. Use these as arguments to
download - hopefully, that helps. I wanted to attach these - however,
taht didn't work for NNTP, so I mail them to you.

This whole mess is another reason to depsise SOAP and stick to xmlrpc or
better CORBA, btw.

Didn't work - my mail server won't let me send these to you. So you're
on your own here. Shouldn't be too hard :)
