ElementTree not finding present tags-CodePudding

Here's how I parse the xml response from this url

import requests
from xml.etree import ElementTree as ET

response = requests.get('https://www.lb.lt/webservices/FxRates/FxRates.asmx/getCurrencyList')
tree = ET.fromstring(response.content)

The response contains (truncated):

b'<?xml version="1.0" encoding="utf-8"?>\r\n<CcyTbl xmlns="http://www.lb.lt/WebServices/FxRates">\r\n  <CcyNtry>\r\n    <Ccy>ADP</Ccy>\r\n    <CcyNm lang="LT">Andoros peseta</CcyNm>\r\n    <CcyNm lang="EN">Andorran peseta</CcyNm>\r\n    <CcyNbr>020</CcyNbr>\r\n    <CcyMnrUnts>0</CcyMnrUnts>\r\n  </CcyNtry>\r\n  <CcyNtry>\r\n    <Ccy>AED</Ccy>\r\n    <CcyNm lang="LT">Jungtini\xc5\xb3 Arab\xc5\xb3 Emirat\xc5\xb3 dirhamas</CcyNm>\r\n    <CcyNm lang="EN">UAE dirham</CcyNm>\r\n    <CcyNbr>784</CcyNbr>\r\n    <CcyMnrUnts>2</CcyMnrUnts>\r\n  </CcyNtry>\r\n  <CcyNtry>\r\n    <Ccy>AFN</Ccy>\r\n    <CcyNm lang="LT">Afganistano afganis</CcyNm>\r\n    <CcyNm lang="EN">Afghani</CcyNm>\r\n    <CcyNbr>971</CcyNbr>\r\n    <CcyMnrUnts>2</CcyMnrUnts>\r\n  </CcyNtry>\r\n  <CcyNtry>\r\n    <Ccy>ALL</Ccy>\r\n    <CcyNm lang="LT">Albanijos lekas</CcyNm>\r\n    <CcyNm lang="EN">Albanian lek</CcyNm>\r\n    <CcyNbr>008</CcyNbr>\r\n    <CcyMnrUnts>2</CcyMnrUnts>\r\n  </CcyNtry>\r\n  <CcyNtry>\r\n    <Ccy>AMD</Ccy>\r\n ...'

From which I need to extract the available currencies in <Ccy> tags. However it's not clear to me why the tags are not found:

>>> tree.findall('CcyNtry')
[]
>>> tree.findall('Ccy')
[]

What I'm trying to do is to access the results printed by the below

>>> for element in tree:
...     print(element[0].text)

CodePudding user response：

Unfortunately, you have to deal with the namespace in the file. So try it this way:

namespaces = {'xx': 'http://www.lb.lt/WebServices/FxRates'}

for element in tree.findall('.//xx:CcyNtry/xx:Ccy', namespaces):
   print(element.text)

The output should be what you're looking for.
