XML file searching

[abaddon2031]

I am workign with a xml file that contains the order information for a company. What i am tryign to do is see if the xml file have a scan code in it and if it does then to pull the order number so that it can be passed to another function. I have a base start but I keep getting the error AttributeError: 'NoneType' object has no attribute 'text' and dont know how to fix it. Could someone explain to me what im doign wrong and how to fix my code.

tree = ET.ElementTree(file=args.destDir + '/' + 'FACTSentered'+args.fileDate+'.xml')
root=tree.getroot()
codeList = root.findall(".//ScanCodes/ScanCode/Code")
code_stats = {}
for el in codeList:
    #order = el.find('OrderNumber').text
    code = el.find('Code').text
    user = el.find('User').text
    if user is None:
        user = '??'
    seq = el.find('SeqNumber').text
    #print order
    print code
    print user
    print seq

What line is causing the error. Perhaps you could post the error message?

It sounds like one of your el.find statements is coming up empty (None) and that's causing the error

[abaddon2031]

its saying all three of the el.find statements are throwing the error i commented out each of them individually and they all throw the smae error

[Gribouillis]

It means that none of the calls to .find() finds anything.

[abaddon2031]

ok thats simple enough now how do i fix it if there is a way to fix it

[snippsat]

codeList = root.findall(".//ScanCodes/ScanCode/Code")
print codeList

What dos "print codelist" output.
So here as a demo i use find() to find "value" and "text"

in [1]:    
xml = '''\
    <foo>
       <bar key="value">text</bar>
    </foo>'''

In [2]:    
import xml.etree.ElementTree as ET

In [3]:    
xml = ET.fromstring(xml)

In [4]:    
xml.find('./bar').attrib['key']   
Out[4]:
'value'

In [5]:
xml.find('./bar').text    
Out[5]:
'text'

the pring codelist prints out the cancodes/scancode/code section to show that it has fount something. Right now its there for debugging purposes.

the pring codelist prints out the cancodes/scancode/code section to show that it has fount something.

Is it in "xml" foramt?
Post a sample.

If i iterate over codelist(for el in codeList:),
like you do i can not use find() anymore.

In [25]:

for el in xml:
    print type(el)
    print el.attrib['key']
    print el.text        

<class 'xml.etree.ElementTree.Element'>
value
text

[abaddon2031]

this is the best i can give for a example had to remove all sensitive information from it and i jsut tried what you have showed with jsut printing the el.text and it didnt pring nothing

I figured out how to get what i was looking for now i have hit another snag that i will have to post another question about. But the answer was to use

for el in codeList:
    code = el.find('Code').text
