Parsing XML: How can I get all the information from lines with same name but different text in XML file using Python?

I'm trying to parse an ICD10 XML file and I'm having some trouble extracting information.

<diag>
<name>A00</name>
<desc>Cholera</desc>
<diag>
  <name>A00.0</name>
  <desc>Cholera due to Vibrio cholerae 01, biovar cholerae</desc>
  <inclusionTerm>
    <note>Classical cholera</note>
    <note>Classical cholera again</note>
  </inclusionTerm>
</diag>
<diag>
  <name>A00.1</name>
  <desc>Cholera due to Vibrio cholerae 01, biovar eltor</desc>
  <inclusionTerm>
    <note>Cholera eltor</note>
  </inclusionTerm>
</diag>
<diag>
  <name>A00.9</name>
  <desc>Cholera, unspecified</desc>
</diag>
</diag>

Using this:

from xml.etree import ElementTree as ET
root = ET.parse('cut.xml')
diag = root.find(".//*[name='A00.0']")
inclusionTerm = diag.find('inclusionTerm')
if inclusionTerm is not None:
    print('Inclusion Term: '+diag.find('inclusionTerm').find('note').text)

the code only prints the first note inside the "inclusion Term" from A00.0 ID. How can I write the code to get all of the 'notes' inside the 'inclusionTerm'?

An XPath expression could be written to access all note elements:

from xml.etree import ElementTree as ET

xml = '''<diag>
<name>A00</name>
<desc>Cholera</desc>
<diag>
  <name>A00.0</name>
  <desc>Cholera due to Vibrio cholerae 01, biovar cholerae</desc>
  <inclusionTerm>
    <note>Classical cholera</note>
    <note>Classical cholera again</note>
  </inclusionTerm>
</diag>
<diag>
  <name>A00.1</name>
  <desc>Cholera due to Vibrio cholerae 01, biovar eltor</desc>
  <inclusionTerm>
    <note>Cholera eltor</note>
  </inclusionTerm>
</diag>
<diag>
  <name>A00.9</name>
  <desc>Cholera, unspecified</desc>
</diag>
</diag>'''

root = ET.fromstring(xml)

notes = root.findall('.//diag[name="A00.0"]/inclusionTerm/note')

for note in notes:
  print(note.text)
