Problem parsing SOAP envelope with ElementTree

[Zvi]

Hi All,

Can someone tell me why id the following not working?
I have a soap response envelope, for test purpose it's just a string
and I create ElementTree from it.
Then I try to find Response tag, but I get None.


data = """<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/
soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body> <Get2Response xmlns="http://
tempuri.org/">
<Get2Result><![CDATA[<?xml version='1.0'
encoding='UTF-8'?> <Response> <Entity Name='Accounts'
Current='00300571B42F1DEC8E9B6CDF19A59950'> <Instance
Id='00300571B42F1DEC8E9B6CDF19A59950'> <Field
Name='Status' Value='2'/> <Field Name='Id' Value='MC4670'/> <Field
Name='Name' Value='ACDC Industries Inc'/>
<Field Name='City' Value='Milwaukee'/> <Field
Name='MainContact' Value=''/> <Field Name='CreatedOn'
Value='20070723051316.0000000 '/> </Instance> </Entity> </
Response>]]></Get2Result>
</Get2Response></soap:Body></soap:Envelope>"""

ElementTree.XMLTreeBuilder = SimpleXMLTreeBuilder.TreeBuilder
dom=ElementTree.fromstring(data)

if dom == None:
return "Empty Dom"

response = dom.find('{http://schemas.xmlsoap.org/soap/
envelope/}Response')
if response == None:
return "Empty Response"

if I try to use
response = dom.find('{http://tempuri.org/}Response') this doesn't work
either.

What am I doing wrong?

snip not working code

What am I doing wrong?

Here is working code.

8<-----------------------------
from xml.etree import ElementTree as ET

data = """<soap:Envelope
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<Get2Response xmlns="http://tempuri.org/">
<Get2Result><![CDATA[<?xml version='1.0' encoding='UTF-8'?>
<Response>
<Entity Name='Accounts' Current='00300571B42F1DEC8E9B6CDF19A59950'>
<Instance Id='00300571B42F1DEC8E9B6CDF19A59950'>
<Field Name='Status' Value='2'/>

<Field Name='MainContact' Value=''/>
<Field Name='CreatedOn' Value='20070723051316.0000000 '/>
</Instance>
</Entity>
</Response>]]>
</Get2Result>
</Get2Response>
</soap:Body>
</soap:Envelope>"""

env = ET.fromstring(data)
result = env.find('*//{http://tempuri.org/}Get2Result')
response = ET.fromstring(result.text)
for elm in response.getiterator():
print elm

In the future please paste complete examples. It helps me to help you.
They were two things that I found to be wrong:
- searching using wrong path. You missed *// in front of the tag
- parsing only once. There are two xml sources here.
The first parse got you the representation of the Envelope.
You have to parse the Get2Result payload to get at the
interesting part

Thanks a lot
P.S. It was a complete code, I didn't write anything else.
