Trying to parse xml throws FileNotFoundError

New to python and all I am doing is parsing a simple xml string. But when I do that, it says ‘No such file or directory’ at Et.parse. I also tried saying Et.parse(Et.fromstring(xmlfile)) but still that leads to a slightly different exception. Please help.

import xml.etree.ElementTree as ET
    
    
thisDict={}
    
def parseXML(xmlfile):
    tree = ET.parse(xmlfile)
    root=tree.getroot()
    for package in root.findall('package'):
    if package is None:
        continue
    if 'id' in package.attrib:
       thisDict['package']=package.get('id')
    if 'version' in package.attrib:
       thisDict['version']=package.get('version')

    for x, y in thisDict.items():
    print(x, y)


xmlstr=f'''<?xml version="1.0" encoding="utf-8"?>

parseXML(xmlstr)

>Solution :

Since the xml is a string you should use ET.fromstring.

For me this worked, but it means that you should adjust your code to not read the file:

xml = '''<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="Castle.Core" version="5.1.1" targetFramework="net481" />
  <package id="Moq" version="4.18.4" targetFramework="net481" />
  <package id="System.Runtime.CompilerServices.Unsafe" version="4.5.3" targetFramework="net481" />
  <package id="System.Threading.Tasks.Extensions" version="4.5.4" targetFramework="net481" />
  <package id="xunit" version="2.4.2" targetFramework="net481" />
  <package id="xunit.abstractions" version="2.0.3" targetFramework="net481" />
  <package id="xunit.analyzers" version="1.0.0" targetFramework="net481" />
  <package id="xunit.assert" version="2.4.2" targetFramework="net481" />
  <package id="xunit.core" version="2.4.2" targetFramework="net481" />
  <package id="xunit.extensibility.core" version="2.4.2" targetFramework="net481" />
  <package id="xunit.extensibility.execution" version="2.4.2" targetFramework="net481" />
  <package id="xunit.runner.visualstudio" version="2.4.5" targetFramework="net481" developmentDependency="true" />
</packages>'''
tree = ET.fromstring(xml)
tree.findall('package')

If you want to use your function you could use theio package:

import io

def parseXML(xmlfile):
    tree = ET.parse(xmlfile)
    root=tree.getroot()
    thisDict = {}
    for package in root.findall('package'):
        if package is None:
            continue
        if 'id' in package.attrib:
            thisDict['package']=package.get('id')
        if 'version' in package.attrib:
            thisDict['version']=package.get('version')

    for x, y in thisDict.items():
        print(x, y)

parseXML(io.StringIO(xml))

note that I added thisDict = {} to your function. But it probably does not what you want, since the 'package' key is overwritten every time a new package is found.
